Make ANY Hex-Head Bolt a Security Bolt
Spin-Guard is a patent-pending new hardware design that instantly converts your existing hex-head bolts into tamper-resistant security bolts.

How does it work?
Spin-Guard is a three-component system that protects any standard hex bolt from unauthorized removal.

Spinner
The spinner is the protective outer shell that rotates freely around the bolt head

Bushing
The bolt head compresses against the bushing, which provides the collar around which the spinner rotates.

Access Key
The specially designed key fits the spaces between the spinner and bolt head to allow access.
Patent Pending

- Install the bolt through the protective stainless steel bushing and spinner
- The access key tool matches the hole pattern on the top of the spinner
- Tighten the bolt to the recommended torque
- Once installed, the spinner prevents access to the bolt head
- If someone tries to grip the spinner, it will just rotate freely
- The bushing carries the load of the bolt, allowing the spinner to move independently and prevent removal
What makes Spin-Guard different?

Use the bolts you already have
Spin-Guard works with standard hex-bolts. No need to source specialized fasteners with specific diameter, thread pitch, material, or finish.

Universal sockets can’t defeat it
New universal pin sockets can remove many security fasteners. Spin-Guard is designed to prevent these tools from engaging the bolt, providing stronger protection against tampering.

Works with larger sized bolts
Most security fasteners only exist in smaller sizes. Spin-Guard protects larger infrastructure bolts where theft and damage is most costly.

Spinner rotates independently
Grabbing tools like vice grips or channel locks cannot defeat Spin-Guard because the spinner turns independently of the bolt head.
Applications
Use Spin-Guard on anything you don’t want stolen, vandalized, or disassembled.
