Patent Pending | Never in Stores
Strip-Lok™ acts like a One-Way, but can be power driven for max torque before intentionally stripping to make the perfect non-removable security screw.
Strip-Lok™ does just what the name says — using the driver bit, the keyway strips out at proper torque. When it strips, that’s it, the fastener is installed. No torque wrench is needed.
Step 2. Nothing. That’s it. The simplicity is what makes Strip-Lok fastener installation so easy.
It’s faster to install than a rivet but much more secure. The Penta-based keyway uses our proprietary Penta-Plus driver bit to drive securely.
Perfect for someone who installs tamper proof screws for demanding customers in tough conditions. For example, the 1/4-20 screws are perfect for this type of need and they strip out perfectly at around 70 in-lbs. A typical power driver can do that all day.
One-Way fasteners were first invented in the early 1900’s, they’re not only outdated, but a terrible fastener to install. What’s more, like most of our competitors fasteners, one needs to only go to a hardware store to buy a tool to remove them. Not so with Bryce flagship security products, including Strip-Lok™.
In fact, there are no videos on YouTube® showing how to remove them.
We do have a removal tool, but it’s only sold to verifed Strip-Lok™ customers.
Strip-Lok™ fasteners are not intended to be removed. To help prevent theft and reduce liability, consider using them for permanent installation circumstances.
Strengthen the security of safes, hinges, hasps, security gates, bolt locks, and public fixtures.
