Metabo HPT 883-507 Hex Socket HD Bolt for Framing Nailers NR83AA2, NR83AA3

The Metabo HPT 883-507 Hex Socket HD Bolt (M6x25) with Split Washer is an OEM replacement hardware pack designed to maintain the structural integrity of high-vibration pneumatic framing nailers. This heavy-duty cap screw is engineered to secure critical housing components, such as the top cylinder cap or exhaust cover assemblies, where internal air pressures and aggressive recoil forces are highest. Each bolt comes equipped with a split spring lock washer that applies continuous radial tension against the bolt head. This configuration mechanically prevents the fastener from backing out or loosening due to the rapid, repeated impacts of daily jobsite firing. Tailored specifically for legendary heavy-duty pneumatic nailer platforms, including the Metabo HPT / Hitachi NR83AA2, NR83AA3, and NV83A2. It also widely supports the extended 83-series family, including the NR83A2, NR83AA5, NV83A3, and NV83A5 framing and coil nailers.
