±10 kN ±100 Nm Linear-Torsion Mechanical Wedge-Action Grips

Designed to suit the ElectroPuls® E10000 Linear-Torsion, the 2742-316 mechanical wedge-action grips are suitable for tension, compression, reverse-stress, and torsion testing on a wide range of specimens and materials. The grips are mechanically operated and the open-fronted design provides easy specimen insertion, positioning, and clamping.

Principle of OperationThe single-acting wedge action principle of these grips is designed to clamp a specimen without applying a compressive load, which could cause a specimen to buckle.

The retracting movement of the grip bodies helps to reduce compressive loads that are normally caused when clamping specimens.

The open front design permits quick and easy changing of specimens and jaw faces. Jaw faces optimize gripping performance whilst the serrated faces are designed to minimize damage to the specimen surface.
Application Range
  • Type of loading: Linear and Torsion tension, compression or reverse-stress testing
  • Specimen material: Metallics, plastics, composites
  • Specimen geometries: Flat or round specimens
  • Temperature range: -70 to +350°C (-94 to 662°F)


  • Fatigue-rated capacity: ±10 kN (linear), ±100 Nm (torsion)
  • Suitable for both linear and torsion tension and compression testing, including full reverse-stress dynamic tests
  • Open-fronted design for quick and easy specimen insertion
  • Interchangeable jaw faces for gripping different materials and specimen sizes
  • Requires no attachment kits when mounting to ElectroPuls E10000 Linear-Torsion
