Screwdriver Bit Gedore 6157140 Weight 131 g Package Depth 80 mm Package Height 50 mm

Gedore 6157140 is a hand-operated screwdriver bit with a stepped hexagon tip of 13 mm. It is manufactured from Gedore vanadium special steel with a pressed-in pin and manganese-phosphated finish, and the tool is chrome-plated for corrosion resistance. The bit uses a square drive according to DIN 3120 (C 12.5) and conforms to DIN 7422, with an integrated ball retaining groove for secure attachment.

Advantages

The bit combines the strength of vanadium special steel and manganese-phosphated protection for improved wear resistance. Chrome plating enhances corrosion protection while the knurled, hand-operated grip aids manual control. Conformance to DIN and ISO drive standards and the ball retaining groove ensure compatibility and reliable retention in matching holders.

Suitable for

• Manual fastening and loosening of bolts with a 13 mm stepped hexagon recess
• Use with square-drive handles or adapters meeting DIN 3120 / ISO 1174 (C 12.5)
• Workshop tasks and maintenance where a durable, corrosion-resistant bit is required

How to use

Select a compatible square-drive handle or adapter (C 12.5 / DIN 3120) and insert the bit until the ball retaining groove engages. Use the knurled grip for manual operations or place the bit in a suitable holder for torque application. Apply steady, even force when tightening or loosening fasteners to avoid slipping or rounding of the stepped hexagon tip.

Usage recommendations

Inspect the bit for wear or damage before use; replace if the hexagon tip shows rounding. Avoid using the bit with impact tools unless it is explicitly rated for impact use. Store dry and clean to preserve the chrome and manganese-phosphated surfaces.
