5 kN Wedge Grips for Metal Specimens

5 kN Wedge Grips for Metal Specimens

These easily-operated wedge grips are for tensile testing thin metal plates and metal wires. Although these grips don’t benefit from the stationary grip face feature of non-shift wedge grips, they still incorporate a wedge design, where the grip faces press against the wedged frame during testing, applying a self-tightening action to hold the specimen firmly in place.

There are two grip sets for 5 kN (1,100 lbf) wedge grips for metal specimens. Both grip sets include upper and lower grips. The difference between the two grip sets is one includes integrated parallel-groove grip faces whereas the other has embedded cross file-teeth grip faces. The grip faces are available separately, and can be interchanged with relative ease.

Operation

To insert a specimen, both grip faces are opened simultaneously by raising the attached pins and then closed by slowly lowering them. During release, the wedge-shaped frame guides the grip faces until contact is made with the specimen. To adjust the clamping tension applied to the specimen, a knurled knob is turned. This knob controls the compression of a spring, which applies tension to the grip faces.
