RAM® Pin-Lock Security Nut for D & E Size Socket Arms

Part# RAP-S-NUT5

UPC: 793442946288



The RAP-S-NUT5 consists of a 1/2"-20 female threaded security nut and key knob. The RAP-S-NUT5 replaces all knobs on 2.25"/3.38" diameter D/E size arms and mounts. The RAP-S-NUT5 offers the ideal amount of leverage to properly tighten your mount to prevent slippage in heavy chop or in extreme vibration environments. With an emphasis on aesthetics and function, the RAP-S-NUT5 is low in profile and only adds a small amount of additional bulk to your system when compared to the standard knob included. At a fraction of the cost of currently available keyed locking knobs, the additional peace of mind and tamper resistance comes at a very affordable price. The RAP-S-NUT5 is the perfect accessory for keeping your mounted electronic device safe from theft and tampering.

High Strength Composite

For the highest security, apply thread-locker liquid to the internal threads of the RAM® Pin-Lock™ Security Nut prior to installation.

For an extra tight grip, RAM recommends the RAM-KNOB9HU Hi-Torq™ wrench. Use the cold weather wrench to tighten the mount for optimal performance. Aftermarket locking knobs are not capable of tightening the RAM® Mount to the required tension to perform in high vibration applications. The addition of an aftermarket knob will make the mount not compatible with the cold weather wrench and will not be able to tighten properly.
