Wedge Clamping Grips for High-Strength Metal and Composite Specimens

Wedge clamping grips are built for high-strength materials such as structural metals and composite laminates, where a firm hold and high load capacity are essential. They are the go-to grip when specimens are hard, rigid, and tested to high force.

Their self-energizing action keeps the hold secure as load climbs. To match a set to your specimens, request a personal quote.

They use a wedge-based jaw mechanism that increases holding force as the tensile load rises. The internal wedge slides against serrated or knurled jaw surfaces, which continue to tighten on the specimen during loading.

Because the grip tightens itself under load, it resists slipping on high-strength specimens. Learn more about our tensile testing equipment.

Side action grips apply a set clamping force, while wedge grips increase force as load rises. For high-strength metals and composites at high load, that self-energizing hold is the key advantage.

It keeps hard specimens secure where a fixed clamp might slip. To compare for your work, talk to our team.

Wedge grips are made for hard, rigid, high-strength specimens, including:

• Structural metals
• Composite laminates

These materials need the firm, high-capacity hold that wedge grips provide. Explore the full grips and fixtures range.

The right choice comes down to a few factors:

• The peak load, up to and beyond 500 kN
• The specimen material and geometry
• Whether you need manual or hydraulic operation

Those point to the specific grip and capacity. Email sales@tensilemillcnc.com.

They cover a broad range, from moderate test loads up to capacities exceeding 500 kN. That makes them suitable for demanding high-force tensile programs.

Matching the grip capacity to your maximum load is important for a secure hold. To confirm the right capacity, request a personal quote.

Yes. Wedge clamping grips are produced in both manual and hydraulic versions, so you can match the grip to your throughput and force needs.

Hydraulic versions suit higher loads and faster, repeatable clamping. To choose between them, talk to our team.

They support common metal tensile methods, maintaining the conditions those tests require:

• ASTM E8 for metals
• ISO 6892 for metallic tensile testing

ASTM E8 defines how metallic specimens are pulled to failure at room temperature to determine yield strength, tensile strength, elongation, and reduction of area, and ISO 6892-1 is its international counterpart for ambient-temperature metallic tensile testing.

Steady clamping and axial alignment are what keep these results valid. See our standards and certification.

Yes. The wedge action means holding force increases as the tensile load rises, so the grip tightens further exactly when a firm hold matters most. This self-energizing behavior is central to their design.

It is why they resist slipping on high-strength metals and composites. Learn more about our tensile testing equipment.

Yes. They maintain axial load alignment and steady clamping conditions for hard, rigid specimens, which keeps the load straight through the specimen.

Good alignment is essential for valid high-force tensile results. Learn more about our tensile testing equipment.

They are used in materials testing laboratories, aerospace and automotive component evaluation, and research settings where standardized tensile tests on high-strength materials are performed.

Their capacity and firm hold make them a fit for structural and high-performance work. Explore the full grips and fixtures range.

Yes. Composite laminates are a primary use, since they are high-strength and rigid and need the firm, self-tightening hold wedge grips provide. Serrated or knurled jaws maintain contact through the test.

This makes them a strong choice for aerospace and composite labs. To set up a composite test, request a personal quote.
