https://www.hollowrivet.com/product/rivets/ Fatigue testing is especially critical in industries where hollow rivets are used in dynamic applications, such as automotive and aerospace. Ensuring that hollow rivets can withstand repeated stress without premature failure is vital to the overall safety and longevity of the structures in which they are used. In addition to tensile and fatigue testing, shear testing is another key performance test for hollow rivets. Shear testing measures the ability of a hollow rivet to resist shear forces, which occur when two parts are pulled in opposite directions. In many fastening applications, hollow rivets are exposed to both tensile and shear forces, making this type of performance testing essential for ensuring the rivet's strength in multiple directions.
