Dual-Action Hydraulic Wedge Grips for High-Force Tensile Testing

Dual-action hydraulic wedge grips are used for high-capacity tensile testing where both stable clamping and controlled jaw movement are needed. They combine two gripping actions in one grip, which makes them versatile for demanding, high-force work.

They are a strong choice for structural and industrial specimens tested at elevated loads. To match a set to your work, request a personal quote.

The grip offers two complementary gripping actions:

• Side-action mode, where the jaws close from both sides under hydraulic pressure
• Wedge-action mode, where angled jaw slides increase gripping force as the load rises

Having both in one grip lets you match the action to the specimen. Explore the full grips and fixtures range.

In side-action mode, the jaws close from both sides under hydraulic pressure, which provides even clamping across flat or wide specimens. That balanced clamping helps maintain alignment during loading.

Even engagement is what keeps wide specimens straight under load. Learn more about our tensile testing equipment.

In wedge-action mode, angled jaw slides increase the gripping force as the tensile load rises, so the grip tightens itself under load. This self-energizing action holds high-strength specimens securely.

It is what keeps steel rods and fasteners from slipping at high force. Learn more about our tensile testing equipment.

A dual-action grip gives you both even side clamping for alignment and wedge self-energizing for a firm hold at high force. One grip therefore covers flat, wide, and high-strength specimens.

That flexibility reduces the number of grips a high-force lab needs. To compare for your work, talk to our team.

They are built for large, high-strength specimens, including:

• Large metal specimens and steel rods
• Fasteners and bolts
• Rebar and structural metals

These are the demanding parts common in structural and industrial testing. Explore the full grips and fixtures range.

They are used with servo-hydraulic universal testing machines, which supply the high force and controlled loading these grips are designed around.

The grip and the hydraulic frame work together as a high-force system. Learn more about our servo-hydraulic testing machines.

Yes. The hydraulic system allows the clamping pressure to be set before the test, which supports consistent specimen engagement from one test to the next.

Setting pressure ahead of loading keeps results repeatable. To plan a setup, request a personal quote.

They are used in construction materials labs, metal processing facilities, and industrial manufacturing environments, where high-force testing of metals is routine.

Their heavy-duty build suits these demanding settings. Explore the full grips and fixtures range.

Their heavy-duty construction supports high load capacities, making them suitable for testing rebar, bolts, and structural metals under elevated tensile forces.

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

Yes. Rebar is a primary use, along with bolts and structural metals, since these need the high capacity and firm hold the grips provide. Wedge-action keeps the hold secure as load climbs.

This makes them a fit for construction and structural labs. To set up a rebar test, request a personal quote.

Yes. In side-action mode the even, two-sided clamping helps keep flat and wide specimens aligned during loading, which keeps the load axial.

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