• Surface: Pyramid (serrated) jaws 1.2 x 45°
• Opening: 0 - 13mm
• Clamping surface: 50mm H x 35mm W
• Hardened steel 58 HRC
• For flat specimens of materials that need a “bite” to secure a good grip

Pyramid Jaws (50mm high x 35mm wide) - nickel-plated having a surface of hardened steel pyramids of 1.2mm tall.

Jaw opening = 4 - 16mm.

For flat specimens of materials that need a “bite” to secure a good grip (e.g. soft metals {aluminium, copper, soft steel, paper and board)

Supplied as 0.5 set = 2 jaws (left & right). Order any combination of 2 half sets of jaws to fit into a pair of any Mec243 Wedge Grips (upper & lower).

A compact lever-actuated wedge grip is available rated to a tensile force of either 20 kN or 50 kN. The initial gripping force is provided by pre-tensioned springs which cause the jaws to close together. The teeth of the jaw face act to make a preliminary hold of the specimen before the main clamping force is applied by the action of the wedges moving as the load is applied to the specimen. A side-action lever arm allows operators to quickly and easily load and release specimens when testing. 

The Mec243 Wedge Grips feature easy interchangeability of jaws making them an ideal universal choice when faced with tensile testing of a variety of shapes and materials. Pyramid (serrated) jaws (Mec243-BP & -BP16) are optimal for testing flat samples up to 16mm thickness. For round samples, up to 16mm in diameter a set of V-shaped jaws (Mec243-BV & -BV16) are available for use with the Mec243 Wedge Grips. Jaws should be ordered separately. 

Both versions of the Mec243 Wedge Grips are especially suitable for holding a variety of materials such as plastic strips and dumbbells, flat and round metal specimens such as sheets, pipes, rods and dumbbells plus textile straps and belts.
