Security Set Screws

Set Screws for All Security Needs

Headless & Secure

Security Set Screws | “Headless” Security Screws | “Grub” Security Screws

We offer flat point security set screws in all five of our security drive styles.

Sizes range from 8/32 (M4) – 5/8-11 (M16). The length on our set screws must be longer than the diameter to permit threading on our machines. 

Drive options

Key-Rex®, STYKFIT®7, and Tam 6-Lobe™ are special order with 2,500 minimum quantities.

Penta-Plus™ and Hex-Pin security set screws are our two most ordered drive styles. Call/Email for stock.

Skateboard "stoppers"

Is your application worth over $100.00?

If you answered no, then Hex-pin and Tam 6-Lobe™ security set screws are the right drives to choose. Skateboard “stoppers” is an example where lower level (Hex-pin and Tam 6-Lobe™) security set screws are needed.

If you answered yes, we recommend going with Penta-Plus™, Key-Rex®, or our STYKFIT®7 security set screws, where the security bits are either exclusive-to-you or controlled by Bryce Fastener. Military weaponry cases and retail product displays are applications worthy of higher level security set screw protection.
