King Tony 3108PR8 nut driver bit is a socket-style bit designed for driving hex nuts and fasteners. The tool is supplied as part of an 8-piece arrangement intended to be used with compatible 3/8" drive bit holders, rails or power tool adaptors. The listing specifies model 3108PR8 and a weight of 340 g. It is intended for repair, assembly and maintenance tasks that require reliable hexagon engagement and socket-style handling.

Advantages

The King Tony 3108PR8 combines socket-style construction with hexagon driving geometry to provide stable contact with hex nuts and fasteners, reducing rounding or slippage during use. The kit form—8 pieces on a 210 mm socket rail with a 3/8" drive clip—keeps bits organized and ready for quick selection and attachment. At the listed weight of 340 g, the item balances portability and durability for workshop or field use.

Suitable for

• Automotive repair and maintenance where 3/8" drive hex sockets are required
• General equipment assembly and disassembly tasks involving hex nuts
• Workshop toolkits that use socket rails and 3/8" drive holders
• Field service and maintenance where a compact set of socket-style hex bits is needed

Key specifications

• Type: socket-style nut driver bit set with hexagon driving ends
• Pieces: 8-piece set
• Drive size: 3/8" drive compatibility
• Rail length: 210 mm socket rail for organizing the bits
• Weight: 340 g (total listed weight)

How to use

Select the appropriate hexagon socket bit from the set, clip it onto a compatible 3/8" drive bit holder or socket wrench adaptor, and engage the bit with the fastener head. Apply steady torque while maintaining alignment between the bit and the fastener to avoid cam-out and rounding. For powered tools, use the recommended speed and torque settings for hex fasteners and ensure the bit is securely retained in the holder before operation.

Usage recommendations

Inspect bits before each use for wear or damage; replace any bit with rounded or chipped edges. Use the socket rail to store bits to prevent loss and to keep sizes readily identifiable. For longer bit life, avoid excessive side-loading and use appropriate torque settings when operating with impact or power tools.
