Slotted Capstan Captive Screws

Slotted Capstan Captive Screws feature cylindrical heads with a number of symmetrical holes around the head’s diameter that can be used to insert cables, wires or levers to then adjust the tension within the application.

They are designed with an unthreaded portion below their head, referred to as a ‘reduced shank’, which is the captive portion of this fastener.

Available as standard in A1 Stainless Steel, this screw is an adaptation of DIN 404 with a plain portion – leaving a reduced core diameter.

These Slotted Capstan Captive Screws are able to be adjusted in fine increments and are unique in that they can be driven via both their slotted drive or their symmetrical holes.

The fasteners are also available in more specialised materials such as Nylon and Brass, as well as others. Optional thread locking patches are also available.

As standard, they are available in diameters between M3 and M6 and lengths from 4mm to 30mm.

Non-standard sizes and materials are available to order, including custom parts made to drawings.
