Knurled Captive Shouldered Thumb Screws

SKU: CP11 Category:

Knurled Captive Shouldered 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.

Our full range of Captive Screws can be found here.

Knurled Reduced Thread Captive Thumb Screws (DIN 464) are manufactured as standard in A1 Stainless Steel, with non-standard materials available to order such as Titanium and Aluminium.

Available at Fastenright in sizes from M3 to M10 and lengths ranging from 4mm to 30mm as standard. Optional thread locking patches are also available.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
