Shear fixtures are designed to test the ability of a fastener to withstand load applied transversely to the axis of the fastener. Single shear fixtures are available for shear tension testing. Double shear fixtures are available for shear compression testing.

Double Shear Fixture for Fasteners

The double shear fixture is made of a high strength tool steel to accommodate the high stress involved in a double shear test. It is a compression type fixture, consisting of a mandrel and an anvil, both with U-shaped cutouts. The anvil supports the fastener during the test and the mandrel applies the compressive force. The mandrel and anvil of the fixture are precision machined as a matched set for a specific size fastener. A separate fixture must be purchased for each size fastener being tested.

Single Shear Fixture for Fasteners

The single shear fixture is made of a ultra high-strength, heat treated alloy steel for durability. It is a tension type fixture using a closed hole design to capture the fastener. This design requires a nut to be used on the bolt or stud being tested to prevent the fixture from separating. A separate fixture must be purchased for each size fastener being tested.
