Filament Grip, 250 N, 10-32 UNF Thread
The Filament Grip is designed for tensile testing up to 250 N of delicate, flexible specimens such as threads and yarns, which may break easily when clamped.
The specimen is wrapped around a grooved 13mm diameter bollard and the free end is clamped tightly in place using a pair of friction washers and a thumbscrew. This minimises the chance of slippage within the grip, or of premature failure of the sample occurring due to stress concentrating at one point. The smooth groove accepts filaments up to 0.8mm in diameter.
Fitted with a 10-32 UNF threaded swivel plate designed to ensure specimen alignment when force is applied. 10-32 UNF threaded hole with grub-screw for connection to the base of a test stand or loadcell.
