## Summary description

The RAM Mounts Pin-Lock 4-Pin Security Nut is designed for D & E size socket arms. Made from durable composite material, it ensures secure attachment and stability for your mounts. The black color adds a sleek look to your setup.

## Long description

The RAM Mounts Pin-Lock 4-Pin Security Nut (RAP-S-NUT5-4U) is a 1/2"-20 female threaded security nut with a keyed knob designed to replace the standard knobs on D and E size socket arms and mounts with 2.25" or 3.38" diameter. Made from durable composite material and finished in black, it provides secure fastening while maintaining a low profile and minimal additional bulk compared to the original knob.
Advantages
The Pin-Lock 4-Pin Security Nut provides increased tamper resistance and theft deterrence by requiring a matching key to loosen the knob. It offers improved leverage for a tighter connection to prevent slippage under heavy chop or extreme vibration environments. The unit is cost-effective compared with other keyed locking knobs and preserves the aesthetic appearance of the mounting system due to its compact design.
Suitable for
Securing electronics on D-size (2.25") socket arms
Securing electronics on E-size (3.38") socket arms
Applications subject to heavy vibration or motion (marine, industrial, automotive)
