Knurled Captive Shouldered Thumb Screws

SKU: CP11 Category:

Knurled Captive Thumb Screws are a variant of the thumb screw made to DIN 464, but designed with a reduced thread – or unthreaded portion – below the head.

Intended to be easily removed and reinstalled when necessary, the addition of the large knurled head simplifies the process as they can be easily operated by hand.

Often used for fastening captive panels on industrial machines, which must be fixed for safety reasons – these fasteners are required by EU law on a number of pieces of machinery.

Available as standard in A1 stainless steel, with optional thread locking patches available.
