Siskiyou's 1/4-inch collet hex drive or SoftTouchª TPI series adjustment screws are ideal for OEM and custom applications and are miniature versions of our 3/8-inch collet adjustment screws. They feature single-wrench-size adjustment and locking screw hex drives. The brass collet includes a built-in travel-lock mechanism to reliably hold device positioning.
TPI series fine and ultrafine adjustment screws are producing industry-leading resolutions and a cost-effective alternative to standard micrometers, where position readout is not a requirement. Adjustment screw contact tips are fitted with a hardened ball bearing for exceptionally smooth adjustment.
Our TPI adjustment screws are fitted with 'black' SoftTouchª drive-knob caps by default.
