Nutsetter bit Bosch Extra Hard, 50 mm length, metal construction

Bosch Extra Hard nutsetter bit, 50 mm length, metal construction — designed for driving and fastening nuts and bolts with impact drivers and screwdrivers. Manufactured from S2 modified steel and treated with an optimized heat-treatment process, this 50 mm nutsetter delivers extra-hard quality and consistent performance for assembly, maintenance and repair tasks. An integrated permanent magnet secures the fastener to the bit head to reduce slippage and simplify single-handed operation.

Advantages

The S2 modified steel composition and optimized heat treatment provide increased hardness and wear resistance compared with untreated bits, extending service life under frequent use. The 50 mm length offers improved reach in recessed or partially obstructed fastener locations while maintaining torsional stability. A built-in permanent magnet holds nuts and bolts in position during insertion, improving handling accuracy and reducing drops.

Suitable for

• Driving and fastening nuts and bolts in assembly and manufacturing tasks
• Maintenance and repair work with impact drivers and screwdrivers
• Installation in confined or recessed spaces where extra reach is required
• General-purpose fastening where a hardened bit is preferred

Key specifications

• Material: S2 modified steel with optimized heat treatment for extra hardness
• Length: 50 mm
• Construction: metal nutsetter with integrated permanent magnet
• Compatibility: suitable for use with impact drivers and screwdrivers
• Intended use: driving and fastening nuts and bolts

How to use

Select the nutsetter bit size matching the nut or bolt head. Insert the bit into the driver chuck or bit holder until it seats securely. Position the magnetic bit onto the fastener to hold it in place, then apply steady pressure and operate the driver at the appropriate torque or speed for the fastener and material. For impact driver use, ensure the driver settings and fastener grade are compatible with the bit's hardened properties.

Usage recommendations

Use the nutsetter with the correct driver type and appropriate torque settings to avoid premature wear. Inspect the bit regularly for rounding or chipping and replace when wear compromises fit. Store in a dry place to prevent corrosion and keep the magnetic tip free of debris for reliable holding performance.
