Axial Tensile

Axial Tensile Fastener Analysis

An Axial tensile test is a method for determining behavior of materials under axial tensile loading. The tests are conducted by fixturing the fastener into the test apparatus and then applying a force to the fastener by separating the testing machine crossheads.

Fastener testing allows you to determine the mechanical properties of externally and internally threaded fasteners, washers, direct tension indicators, and rivets. Testing may consist of a machined specimen or a full-size product. The type of fastener testing that will be described below applies to a full-size product testing. Fastener testing is not applicable to all. The head design, shank thickness, and product length can determine if the testing is required of the product.
