Some rivet heads project out from the surface of a part after installation, where others lay flat or flush with a surface.
Head type is especially important for applications where drag and wind resistance are determining factors, or when the rivets are being installed on moving parts. Round Head Rivets : are the most commonly used type of rivet and feature a dome shaped head and a flat bearing surface.
This head style sits higher on the surface than other rivet styles. This aerodynamic rivet style sits flush with a material or part surface once installed and are frequently used for applications involving moving or rotating parts.
The length measurement for this rivet style includes the head and tail or shaft. The head of the rivet in included in the length measurement. Universal Head Rivets : also known as button head rivets, this style has a rounded head with a lower profile than standard round head rivets. Flat Head Rivets : have a head that lays flat on the part or material surface. Brazier Head Rivets : button head rivets that feature a wide, shallow head that provides a larger bearing surface under the head for greater resistance to pull through.
Modified Brazier Head Rivets : button head rivets that feature a lower profile head design than full brazier head rivets. Rivet Head Markings Since solid rivets are produced in a range of materials that, special markings are placed on the head of a rivet to help identify the type of alloy used.
This is important because rivet materials are chosen based on unique properties such as corrosion resistance of yield strength that are required by the intended application.
No mark alloy code A : or pure aluminum Dimple alloy code AD : aluminum alloy Raised dot allow code D : aluminum alloy Raised double dash alloy code DD : aluminum alloy Raised cross alloy code B : aluminum alloy Raised circle alloy code E : aluminum alloy Raised double dimples M : Monel steel Recessed triangle: carbon steel F: corrosion resistant steel C: copper Rivet Codes Various codes are used to specify rivet material type, head type, diameter, length and industry specifications.
See the information below for an overview of the codes used for our products and in our Rivet Identification Chart. Here is a quick overview of how to identify the different parts of a rivet numbering system: Example: ANAD rivet 1. The first set of letters and numbers refers to the industry specification military standard : AN - When these two letters precede numbers, they indicate Army and Navy Specifications.
The next number is the rivet diameter: The diameter of a rivet is indicated in 32nds of an inch.

Too small a hole will, of course, make rivet insertion difficult. Too large a hole will reduce the shear and tensile strengths. It may also cause bulging or separation of the members by allowing the rivet to expand between them instead of only on the blind side. Best practice is to follow the hole size recommendations provided.
The recommended thickness range over which the body length will consistently provide a proper setting in a hole of the specified diameter. First determine the single-joint tensile and shear values required for the application. These are functions of total joint strength, fastener spacing, rivet body material, and rivet diameter.
Measure the total thickness of the materials to be joined. This determines the required "grip" of the rivet you select.
You must select a rivet with a grip range that includes the work thickness required. Remember that insufficient rivet length will not allow proper formation of the secondary head at the back of the work. Both the rivet and the materials to be fastened will affect the ultimate joint strength. As a rule, the rivet materials should have the same physical and mechanical properties as the materials to be fastened, because a marked dissimilarity may cause joint failure due either to material fatigue or galvanic corrosion.
The low-profile domed head is appropriate for most applications. However, when soft or brittle materials are fastened to a rigid backing member, the large flange head should be considered because it offers twice the bearing surface.
Where a flush surface is required, the countersunk head style should be selected. This illustration provide a graphic representation of the rivet selection factors to be considered:. Hole Size Hole size can be important in blind riveting. Avoid burrs in and around the holes. Grip Range The recommended thickness range over which the body length will consistently provide a proper setting in a hole of the specified diameter.
Shear The load applied to a fastener along the joint interface.
Tensile The load applied to a fastener along its length.The Sagulator helps you design shelves by calculating shelf sag deflection given type of shelf material, shelf load, load distribution, dimensions, and method of attachment. You can also specify an edging strip to further stiffen the shelf. See the notes below for usage tips.
The deflection calculations use average wood stiffness properties of clear, straight-grained samples measured in controlled laboratory conditions mainly from the U. Forest Products Lab. Expect some real-life variation from the calculated results. The Sagulator computes initial sag only. Thus, a suggested target for allowable sag is 0. Once you have a maximum allowable sag figure in mind, you can design your shelf by tweaking the material types and dimensions.
A value of 35 pounds per running foot is used by some for library shelving. Fine Woodworking magazines can weigh up to 40 pounds per foot.
You can enter fractional dimensions as decimals 8. If you use fractions, just make sure to leave a space between any leading whole number and the fraction. The shelf thickness value is actual thickness, not nominal. This calculator can also be used to measure beam deflection. The shelf span parameter represents the beam span.
If your melamine sheet has a different particleboard grade M-2, M-3, etcselect that grade of particleboard in the pull-down menu. The melamine facing has a negligible effect on the stiffness of the shelving material.
If using a hardwood ply with a composite core — veneer center plies, with relatively thick MDF outer layers under the face veneers, select MDF for the shelf material. An optional edging strip can be specified to stiffen the shelf. The Sagulator employs established engineering formulas for calculating beam deflection. Some references that I found useful include:.
Special thanks to Steve Stephenson for providing initial formulas and Jeff Bratt for his helpful input and derivation of formulae for handling an edging strip.

Drilling Rivet holes should be drilled in accordance with the following recommendations a. All holes shall be drilled normal at 90 degrees to the working surface. Extreme pressure shall not be applied and holes shall not be punched through with the drill. When drilling through more than one sheet, hold the sheets securely together so there is no misalignment of holes due to shifting or separation of the sheets. Piercing Only piercing tools which produce-true and clean holes, equivalent to acceptable drilled holes should be used.
If piercing is used, all holes need be inspected for radial cracking. Mating surfaces should be cleaned before parts are riveted together, all chips, burrs and foreign material must be removed from the mating surfaces.Edge Distance for Rivet Holes
Burrs may be removed from rivet holes by chamfering to a depth not to exceed 10 percent of the stock thickness, or 0. Oversize countersinks: When countersinks are enlarged beyond specified tolerances, the next larger size rivet may be used, provided pitch and edge margin design requirements are maintained.
Repair limitations: The combined oversize rivet hole repairs and oversize countersink repairs should be limited to a maximum of 20 percent of the rivets, or 10 rivets in a single rivet pattern, whichever is less. Repairs to more than two adjacent oversize rivets, or replacing more than half the rivets with oversize rivets in any 10 inch length of pattern is prohibited. Minimum Pitch inches for repair using oversize rivets only. Provide a minimum of. Otherwise, maintain the normal edge distances, both visible and invisible.

Quant has a Ph. Rivets, made of strong materials such as steel and aluminum, hold pieces together when assembling objects.
Because the parts held by a rivet can pull apart from each other with considerable force, it is important to know how much load a rivet can take before the stress forces break the metal.
In particular, the shear strength of a rivet measures the amount of force that can be applied transversally i.
Aerospace - MIL Spec Solid Rivets
You can compute the shear strength of the rivets you use in your projects. Determine the area of the cross section of the rivet, either from manufacturer's specifications or by cutting a rivet apart transversally.
Replace D by the diameter of the rivet, measured using the calipers. Replace D by the outer diameter of the rivet, and t by the thickness of the rivet's wall, measured using the calipers. Find out the shear strength of the metal the rivet is made of, by looking it up on Table 2 on "Mechanical Properties of Metals" table. Replace S by the shear strength of the metal found in Step 2. Your rivets can tolerate shear forces of up to F Newtons before breaking apart.

There are several reasons for using the riveting method, among which the low cost of installation, the lower requirements for hole preparation, high reliability, light and strong joint due to the low weight, resistance to fatigue due to the high elasticity and durability.
A general rule is that the rivet should have a diameter of at least three times the thickness of the thickest sheet that is being joined. According to the military standard, so the bucked counter head diameter of the rivet joint must be larger than 1. The height must extend to 0.
With all mentioned parameters, you can calculate the desired length of the rivet. The allowance is normally about 1. For example, two pieces of 0. The proper diameter rivet would be 3 x 0.
The metal thickness is 0. See image below:. In practical, for riveting such as overhaul and repair riveting, the general rule is to use the same size and head-style used in the adjacent structure. This will meet all the strength requirements for the joint. Another topic related to the rivet is the hole preparation. After selecting the rivet size and placing the sheets, the holes must be marked for drilling. These hole-marks should be punched with a center punch just deep enough to start the drilling.
If the punch is too hard, the mark will be too large and the metal will be distorted. The drill diameter depends on the type of rivet in the hole:. Notice in the table that the drill size is about three thousands of an inch larger than the rivet. Before start drilling it is important to check the condition of the drill and if the tool is properly attached in the chuck. Click here to check the condition of the drill. After drilling, remove the burrs from the hole without chamfering the hole edge.
Sometimes the sheets can move or gap, in these cases you must use skin pins or clamps considering they will prevent the two holes from interfering and keep the sheets close together when it is time for riveting.
