Slotted Captive Thumb Screws are a specialised variant of DIN 465 thumb screws with a slotted drive to allow the use of a slotted screwdriver. They also host a knurled head which improves the screws usability by hand.
They feature an unthreaded portion below the head, which is often referred to as a reduced thread.
Captive fasteners provide a secure joining which helps to avoid the loss or damage of a fastener within an assembly by stopping the full removal of the screw.
Often found in fastening sheet metal or captive panels for safety reasons, the screws are designed to be compliant with the EU machine safety directive.
Available from Fastenright as standard in A1 Stainless Steel, with optional thread locking patches available.
Thread diameters ranging from M3 to M6, with lengths available from 12mm to 20mm.
Non-standard sizes and materials are available to order, including custom parts made to drawings.
d1 and L1 dimensions can be to customer specification.
