#8 TPI adjustment screw, .25 travel

Siskiyou's 1/4-inch collet Hex Drive TPI series adjustment screws are ideal for OEM and custom applications and are miniature versions of our 3/8-inch collet adjustment screws (see page 89). 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 available with 80 and 100 threads-per-inch pitches, producing industry-leading resolutions — 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.
