Nut Driver Bit KWB 372213 1 pc 76.2 mm Shank 13 mm Size

The KWB 372213 nut driver bit is a single-piece insert for 13 mm nuts designed to work with a 76.2 mm shank. Made from chrome vanadium (CrV) steel with a matt chrome plating and a wave profile, this bit offers a balance of durability and reliable contact with fasteners while protecting their edges.

Advantages

Constructed from CrV steel with matt chrome plating, the bit provides corrosion resistance and long service life. Its wave profile and rounded corners improve force transmission and reduce the risk of rounding off nut edges, helping to maintain grip during tightening and loosening operations.

Suitable for

• Tightening and loosening 13 mm nuts
• Use with tools that accept a 76.2 mm shank
• General mechanical and DIY fastening tasks

When it may not be suitable

This nut driver bit is intended for 13 mm hexagonal nuts and tools compatible with a 76.2 mm shank; it is not suitable for other nut sizes or non-compatible drives. It is also not designed for applications requiring insulated or torque-limited bits.

Key specifications

• Material: chrome vanadium (CrV) steel
• Surface finish: matt chrome plating
• Drive profile: wave profile with rounded corners
• Size: 13 mm nut fit
• Shank length compatibility: 76.2 mm shank
• Quantity: 1 piece

How to use

Insert the bit into a compatible holder or tool with a 76.2 mm shank, seat the 13 mm end fully onto the nut, and apply steady torque while keeping the bit aligned with the fastener. Use controlled force to avoid slippage and inspect the nut and bit for wear before repeated use.

What to consider before purchase

• Confirm that your tool accepts a 76.2 mm shank.
• Ensure the fastener size is 13 mm.
• Check whether a non-insulated metal bit is acceptable for your application.

Usage recommendations

Use the nut driver bit with appropriately sized tools, avoid excessive impact or torque beyond the manufacturer's specifications, and store dry to preserve the matt chrome finish and prevent corrosion.
