Ruuvauskärki Wera 05056176001

The Wera 05056176001 screwdriver bit is a precision slotted bit with a 1/4" (6.3 mm) hex shank and a working length of 25 mm. Its tip is treated with microscopic diamond particles to improve seating in the screw head, lower the required pressing force and reduce the risk of slipping. The bit includes a torsion zone that diverts kinetic energy under peak loads and a softer bi-torsion section to prevent twisting of the tip under high stress, which extends the tool's service life.

Advantages

The diamond-particle tip provides a more secure hold in slotted screws and reduces cam-out. The integrated torsion and bi-torsion zones absorb peak torque loads, decreasing stress on both the bit and the fastener and extending bit lifetime. The 1/4" hex shank conforms to DIN ISO 1173-D 6.3 and fits common bit holders and screwdriver handles, offering reliable compatibility for professional and DIY use.

Suitable for

• General fastening and loosening of slotted screws
• Precision assembly and repair work
• Professional trades and DIY projects requiring durable bits

Key specifications

• Brand: Wera
• Model / MPN: 05 056176 001
• EAN: 2050000315572
• Bit type: Slotted (flat) tip with diamond particles
• Shank: 1/4" (6.3 mm) hex, DIN ISO 1173-D 6.3 compatible
• Length: 25 mm working length

How to use

Insert the 1/4" hex shank into a compatible bit holder or screwdriver handle. Position the diamond-particle tip squarely in the slotted screw head, apply steady axial pressure and turn the driver. The torsion zones will absorb torque peaks; avoid excessive side load or levering to maintain the tip geometry and prolong service life.

Recommendations

Use the bit with appropriate holders that secure the 1/4" hex shank and select the correct slotted tip width for the screw to minimize wear. Replace the bit if the tip shows visible rounding or damage to preserve screw heads and ensure safety.
