Slotted Countersunk Reduced Thread Captive Screws

SKU: CP19 Category:

Slotted Countersunk Captive Screws are the perfect combination between a flat-headed countersunk screw and a captive shank.

This captive shank is also referred to as a reduced thread.

Importantly, the screw complies with the EU safety directive regarding machine guards.

They are also used to fasten sheet metal or captive panels, which are held in place between the head of the screw and a captive washer, which prevents full removal.

Available in both A2 and A4 stainless steel as standard, with optional thread locking patches available.

Other materials, sizes and finishes are available to order as specials.

Please contact us to further your enquiry.
