Choose specialized grips when a general-purpose setup cannot hold the specimen securely and concentrically throughout the test, or when the test method requires a specific loading condition beyond straightforward tensile clamping. The goal is to prevent slippage, reduce specimen damage at the jaws, and improve repeatability.

Specialized grips are typically the better choice when you are dealing with any of the following:

• Thin, flexible, or high-elongation specimens where grip force needs to increase with load, such as films and rubber, using eccentric roller grips.
• Wire, rope, or cable where conventional jaws tend to slip, using snubbing or capstan-style grips.
• Bolts, studs, screws, or nuts where threaded engagement is needed instead of jaw clamping, using threaded grips.
• High sample volume where fast, consistent clamping improves throughput, using pneumatic grips.
• Non-standard loading like bending, compression, peel, tear, or puncture, using dedicated fixtures.
