These open front lever operated grips, known as “K” grips, have a positive, self-aligning gripping action and allow rapid sample insertion and removal. The grips are supplied as standard with flat file inserts, but solid or insert type vee wedges can be supplied for round specimens.
At some capacities, Tinius Olsen offers a choice of wedge angle – an 8½° angle for maximum gripping pressure (recommended for hard, smooth-faced materials) or a 15° angle for a wide range of sample types.
The suspended wedge tensile grips are used on ST and SL series materials testing machines.
