The RAP-S-NUT5-4U consists of a 1/2"-20 female threaded security nut and key knob. The RAP-S-NUT5-4U replaces all knobs on 2.25"/3.38" diameter D/E size arms and mounts. The RAP-S-NUT5-4U 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-NUT5-4U 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-NUT5-4U is the perfect accessory for keeping your mounted electronic device safe from theft and tampering.

Hannah S. ★★★★★

Installed this security nut on my 2.25" arm mount and it's a perfect fit—the key knob is a nice touch for quick adjustments while still keeping things locked down.

Julian F. ★★★★★

Installing this on my RAM mount was straightforward, and the 1/2"-20 threading is exactly what I needed for a secure fit. I feel much better knowing my gear can't be casually swiped.

Mia L. ★★★★★

The key knob makes tightening this down a breeze, and the 1/2"-20 female threads locked onto my D-size arm perfectly. Swapped out all the old knobs on my mount setup and haven't had a single bit of play since.
