Pop rivet drill bit size11/24/2023 ![]() ![]() Blind rivets that meet ISO 15978 (formerly DIN 7337) comply with international dimensional standards for blind rivets. What is a Pop Rivet Courtesy: Amazon Blind rivets, often called pop rivets, are a type of rivets. REACH (Registration, Evaluation, Authorization and Restriction of Chemicals). In this article, you will learn the function of the pop rivet, the pop rivet sizing chart, the removal of a pop rivet, and its application. This compensates for the reduction in rivet shear strength resulting from high bearing stresses on the rivet at t/D ratios less than 0.33 for single-shear joints and 0.67 for double-shear joints. Fabrication & Quality Sarah DeGuzman Share The pop rivet holds two materials together with a clamping force. In calculating protruding-head rivet design shear strengths, the shear strength values obtained from Table 8.1.2(b) should be multiplied by the correction factors given in Table 8.1.2.1(b). The ones you have quoted look reasonable, in thin material some would just run the same size drill up and down a few times to get a clearance. ![]() The harder it is to secure the rivets in place at the end means it is a more secure fit. Imperial sizes would use number and letter clearance drills eg: 1/8 would be a 30 and 5/32' a 21 which provide a few thou over but these are specialized and expensive. You must take careful measurements of the rivets in order to choose the right drill bit to drill the holes. For the double shear strength of a rivet, the values in the table below can be doubled. Just as important as choosing the right rivets, is how large you drill the holes for the rivets. These strengths are the solid rivet shear strengths and describe the shear strength of the shank of the rivet. Rivet Shear Strengths are taken from (MIL-HNDBK-5H, 1998) Table 8.1.2(a) and Table 8.1.2(b). When you need to convert mm to inches, you have to multiply the mm value by 0.0393701. ![]() As it compresses further, it clamps the sheet materials together. This compresses the body of the rivet, causing it to expand radially. Then, the mandrel (also known as a stem) is pulled by the jaws of the setting tool. Rivet Shear Strengths for common rivet materials, drill bit sizes and modification for sheet thickness When drill bit diameter size is available in mm it can convert into inches easily. All types of blind rivets, including dome head rivets, are fitted by inserting the body into a drilled or punched hole. ![]()
