Permanent One Way Security Fasteners

One-way security screws and fasteners, suitable for applications where the fixing will never need to be removed. One-way screws feature a head which is designed to turn in one direction only and will cause cam-out if turned the other way.

One way screws

Many of our permanent one way screws can be secured using standard tooling due to their unique design, with some also requiring security bits

If future maintenance may be required, we suggest using removable security fixings.
