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. Always consult manufacturer's data for the exact specifics.Blind rivets are sized by a combination of two important dimensions. Closed End Rivets, compared to open end rivets of the same size and material, provide greater shear and tensile strength. Also, aluminum rivets with aluminum mandrels are the least strong aluminum rivets with steel mandrels are stronger steel rivets with steel mandrels are stronger still and stainless steel rivets with either steel or stainless steel mandrels are the strongest. When sizing blind rivets, the larger the size the stronger the fastened joint in both shear and tensile. Blind rivet nominal diameter, rivet number, length and grip range. Use the chart below to determine the correct blind rivet for the job (all sizes are in inches). If the total thickness is more than the maximum, the rivet may not set correctly and strength will be compromised. If the total material thickness, including any backup washer, is less than the minimum specified grip range, the fastened connection will be loose. Blind rivet hole sizes and drill bit numbers. When installing blind rivets, there are two things to consider: hole size and grip range. For extra strength, use a square or round backup washer designed for blind rivets to give extra support when fastening soft materials and in applications that require a larger diameter surface to prevent pull-out (see our listing under "Backup Blind Rivet Washer"). When vapor and liquid tight fastening is required, use a closed end rivet (its blind end is solid and remains closed even after setting). Most blind rivets are open end, which means that the rivet body is completely hollow.

Stainless Steel Rivet & Stainless Steel Mandrelīlind rivets are popular because they install quickly and easily they produce strong reliable fastenings (if the mandrel breaks off, the rivet is installed correctly) they are vibration and tamper resistant and the rivets and installation tool do not mar the surfaces of the material being joined.
At a predetermined point, the exposed mandrel will break off inside the rivet.īlind rivets are available in different head styles like dome, large flange, and countersunk, and in different combinations of materials, which affects strength and corrosion resistance… Installation of blind rivets is easy: (1) insert the rivet into a hole that passes through the items to be joined (2) insert the mandrel into the special installation tool (3) "set" the rivet by pulling on the mandrel, which creates a bulge that permanently and securely fastens the items. Blind rivets are also known as "pop" rivets because POP® is one brand of blind rivets.Ī blind rivet consists of two pieces that are pre-assembled: the rivet body (usually just referred to as the rivet) and inside it is the setting mandrel (commonly just called the mandrel).

Fastener Tech Data | Understanding Series IntroductionĪ blind rivet is a rivet that can be completely installed from one side, unlike machine screws and nuts, which requires access to both sides of the material.
