About Allen CSK Screws

The head is countersunk at 90° so it sits flush with the surface, and the hexagon socket takes more torque than a slotted or Phillips screw. The common standards are DIN 7991 and ISO 10642.

Applications

Machine tables, slides and guide rails
Dies, moulds and fixtures
Conveyor and packaging machines

Allen CSK Screw FAQs

What is the difference between an Allen CSK screw and an Allen cap screw?

Both use an Allen key. The CSK screw has a flat countersunk head that sits flush. The Allen cap screw has a round head that sits on top of the surface or in a counterbore.
