Security Fasteners
Security fasteners are specialised screws, bolts, and nuts designed with unique drive configurations to prevent unauthorised access, tampering, theft, and vandalism. They are widely used in public infrastructure, automotive number plates, electronics, and high-security installations. These fasteners fall into two main categories: two-way (reusable), which require a matching proprietary tool for removal, and one-way (permanent), which are engineered to be installed easily but cannot be undone with standard tools.
Security Screws
- Security Self Tappers
- Security Self Drill Screws
- Security Machine Screws
- Button Head Security Screws
- Countersunk Security Screws
Drive Types
- Torx Pin
- Hex Pin
Additional Stock Lines
- Shear Nuts
- Saddle Bolts
