![]() Where a flush surface is required, the countersunk head style should be selected. 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. The low-profile domed head is appropriate for most applications. Rivets with sizes between 2-20 mm as well as sizes between 5-50 mm are common for general usage. 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. Nature of materialsīoth the rivet and the materials to be fastened will affect the ultimate joint strength. Remember that insufficient rivet length will not allow proper formation of the secondary head at the back of the work. You must select a rivet with a grip range that includes the work thickness required. This determines the required "grip" of the rivet you select. Measure the total thickness of the materials to be joined. POP ® brand rivets are not certified for structural aerospace applications and such use is not recommended. Then refer to the "Shear" and "Tensile" in the Rivet Selection Guide on the product and select a POP ® brand rivet that provides the values required. These are functions of total joint strength, fastener spacing, rivet body material, and rivet diameter. Joint strengthįirst determine the single-joint tensile and shear values required for the application. Aluminium 50pcs packed in a bag with paper hanger STOCK NO. The load applied to a fastener along its length. The load applied to a fastener along the joint interface. The recommended thickness range over which the body length will consistently provide a proper setting in a hole of the specified diameter. (Best practice is to follow the hole size recommendations provided).Īvoid burrs in and around the holes. 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. Too large a hole will reduce the shear and tensile strengths. Too small a hole will, of course, make rivet insertion difficult. Hole size can be important in blind riveting. ![]() Without knowing what the proprietary letter codes indicate you can still see that this is a size 45 rivet.This illustration provides a graphic representation of the POP ® blind rivet selection factors described below. For example a companies part number might look something like D45AA. It common for individual rivet manufacturers to use their own part numbers that include the rivet size as well as proprietary codes indicating material, rivet type, or other identifying information. Please note that the worth of D (diameter) is the minimum choice of the rivet shank diameter, and the rivet. A 1.5 D (For rivets of sizes of the rivet shank as much as 20 mm). Length of Rivet Shank (L) S + Allowance (A). permanent riveting, the bur size should correspond to the rivet size. You will find rivet trade sizes listed in our catalog in () for easy ordering. Minimum Diameter of Rivet Shank (D) Thickness of all sheets to be signed up with (S)/ 4. Belt rivets ( A ), made of brass or copper, come in sizes 8, 10, 12, and 14. Therefore a size 45 rivet is 4/32" (1/8") diameter with a 5/16" maximum grip range. The second number refers to the maximum grip length in 16ths of an inch. The first number refers to the diameter of the rivet in 32nds of an inch. The most common way to specify a rivet size is by 'trade size'. Occasionally you may see rivets referred to by only the diameter and maximum grip. ![]() The same rivet would be notated in fractions as: This is a rivet with a 1/8 inch diameter body and a grip range of 0.251 inches to 0.312 inches. In our catalog you will see rivet sizes notated in the form: For details on grip ranges see Using Blind Rivets. ![]() It is very important to note that the maximum grip range is NOT the length of the rivet body. The grip range is the minimum and maximum grip the rivet is intended to be used with. Grip is the thickness of the material being riveted. Blind rivets are sized by a combination of two important dimensions. ![]()
