ASTM D4562 Test Specimens
Pin and collar test specimens used in ASTM D4562 (Shear Strength of Adhesives) testing. This test measures the shear strength of curing liquid adhesives used for retaining cylindrical assemblies or for locking and sealing threaded fasteners. Each test specimen consists of a pin (0.498-499" diameter, 2" long) and a slip collar (1/2" ID, 0.435-439" wide). The test specimens can be made of any material, but are most commonly made of 1008 steel.
