It is important to choose the correct rivet material for a given job. This is extremely difficult to correct as the rivet must be drilled out, any material remaining between the pieces removed, and a new larger rivet hole created as drilling out the rivet will result in a widening of the original hole. If you attempt to pull materials together using a blind rivet, the rivet can begin to expand between the materials as shown below. Rather they should be used to fasten materials that are already temporarily clamped or otherwise held together. Like many other fasteners blind rivets are not meant to pull materials together. Change bits often to avoid 'wobble' caused by dull bits.Be careful not to 'wobble' while drilling.Use the exact specified drill bit (click on a product number to find the bit size).Even a small increase in hole size can result in drastically reduced holding power in both tension and shear. Flat HeadĬorrect hole size is absolutely vital to obtaining maximum holding power from blind rivets. Therefore, while more expensive, a few sizes can cover a wide variety of jobs.įor flat head rivets it is vital that the head of the rivet be completely within the top material being fastened. Multi-grip rivets compact down better and thus have wider grip ranges. In some cases this could interfere with other parts. 250" minimum grip length can be used below that thickness but will leave more material than necessary on the blind side (1) than a properly sized rivet (2). This particular rivet measuring long would actually have grip range of 3/8. After nearly a century, pop rivets are still the most common blind rivet used for manufacturing and applications across many industries. The grip range capability of each blind rivet is listed in a. The minimum grip is the point at which a shorter length rivet exists which can be used. One rule of thumb is a rivets grip is about 1/8 shorter than its measured length. Pop rivets are ideal for assembling aluminum aircraft since they can be installed from one side (which is why they are called blind rivets). Grip Range the rivet grip range refers to the total thickness of the materials to be joined. The maximum grip is the thickest combination of materials the rivet can properly hold together. Blind rivets list a minimum and maximum grip.
