WebThe Bolt Shear Fixture is used to test bolts, fasteners, nails, screws, and other cylindrically shaped specimens. Bolt shear is one of the simplest types of shear tests. ASTM D905 … Webdesigned. Most procedures use a double shear fixture, but variations in the test fixture designs cause a wide scatter in measured shear strengths. To determine the shear strength of the material, the total cross-sectional area of the shear plane is important. For shear planes through the threads, we could use the equivalent tensile stress area ... WebNASM 1312-13 defines the procedure and apparatus for testing fasteners in double shear in a half-hole fixture. The standard replaced MIL-STD-1312-13A.
