Made from durable composite material, it provides secure locking for your mounts, ensuring stability and reliability during use. This nut is essential for maintaining the integrity of your RAM Mounts setup, making it a valuable addition to your mounting solutions.

## Long description

The RAM Mounts Pin-Lock 4-Pin Security Nut (RAP-S-NUT5-4U) is a 1/2"-20 female threaded security nut and key knob designed to replace standard knobs on 2.25"/3.38" diameter D and E size socket arms and mounts. Made from a durable composite material, it provides a low-profile locking solution that increases tamper resistance and helps prevent slippage of mounted devices in heavy chop or high-vibration environments.
Advantages
The RAP-S-NUT5-4U offers keyed locking with four-pin security while maintaining a compact, low-profile design that adds minimal bulk compared to the standard knob. It provides increased leverage for proper tightening to reduce movement and slippage, is more affordable than many competing keyed knobs, and is constructed from a durable composite that resists wear in demanding conditions.
