The RDRP B74 Battery Strap Thumb Nut is larger in diameter than the stock parts for improved grip and easier battery swaps. The design allows the battery to be installed and removed without tools – unlike the stock thumb nuts that require the use of a 7mm nut driver. The thumb nut is machined from high-quality 7075-T6 aluminum, with silver chamfered edge details for looks and a black anodized surface for wear. The thumb nut is a direct replacement, usable with all common B74-series battery braces.
