Fatigue testing grips are used on dynamic universal testing machines to test sample specimens over multiple cycles. These special vise action fixtures are capable of both tensile and compression forces. A solid block is used to backstop the sample and create compression. The sample is gripped laterally by tightening the screws on the side of the fixture.
Fatigue testing grips are custom designed and machined to order. They take a few extra weeks for delivery. These grips are machined from hardened steel and designed for high durability.
