Bolt Lock joined with Monster Hook to provide its "Breakthrough One-Key Lock Technology" on a new swivel hook.

Swivel hooks produced by Monster Hook are already sturdy due to being crafted from aircraft grade 6061-T6 aluminum, but the Bolt Lock technology will bring added security by supplying a lock specifically programmed to the vehicle's ignition key, according to the two companies. 

Recovery hooks are an important accessory for pickup trucks. Monster Hooks swivel hooks are designed to be 99% faster than other 3/4-inch pin shackle hooks due to the latching mechanism rather than the standard method of unscrewing the top to loop the tow strap.

The addition of the Bolt lock located on the hook itself prevents the pin used to attach the hook to the vehicle from moving freely when locked. Using Bolt lock technology, the new Locking Recovery Hook will be the first locking hook on the market. Using specially crafted tumblers, Bolt locks memorize the vehicle's ignition key upon the first insertion and rotation.

Each lock produced by Bolt is make/model/year specific due to the differences of the keys produced by each vehicle manufacturer. By programming each lock to the vehicle's ignition key, Bolt removes the hassle of key clutter and makes the locks harder to tamper with, providing a more secure and convenient option.
