0.5 TRAVEL TPI ADJUSTMENT SCREWS

TPI adjustment screw, .5 travel

Siskiyou TPI series adjustment screws are ideal for OEM and custom applications. They feature our single-wrench-size adjustment for capstan and hex drives and locking screw. The unique collet design incorporates a split-clamp mechanism used to preset adjustment screw tension, as well as locking screw movement. If the location of the locking screw is not ideal, it can be backed out and inserted from the opposite side.

The tip of the adjustment screw has been machined to accept a hard ball bearing (64 Rockwell) that can rotate in the end of the screw. This feature minimizes the amount of rotational torque transferred from the adjustment screw to the translation stage.
