Hex socket screw 8-TPI

brassminiaturewith locking function

The #8-TPI Series Adjustment Screw from Siskiyou is designed for OEM and custom applications, offering a miniature version of the company's 3/8-inch collet adjustment screws. These screws feature a single-wrench-size adjustment and locking screw hex drives, with a brass collet that includes a built-in travel-lock mechanism to reliably hold device positioning. The TPI series fine and ultrafine adjustment screws deliver industry-leading resolutions and serve as a cost-effective alternative to standard micrometers where position readout is not required. Each adjustment screw contact tip is fitted with a hardened ball bearing for exceptionally smooth adjustment. By default, TPI adjustment screws are equipped with 'black' SoftTouch® drive-knob caps.
