Screwdriver bit set Wera Bit-Check 6 pieces

Wera Bit-Check with six 50 mm long square screwdriver bits arranged compactly in a practical holder. High-quality bits with a holding function that use wedging forces from contact pressure between the drive tip and the screw profile to secure the screw on the tool. Bits have 1/4" hex shank and fit holders conforming to DIN ISO 1173-F 6.3.

Advantages

The set offers durable, precision-machined bits that enable reliable torque transfer and reduced cam‑out. The holding function keeps screws on the bit during insertion, improving handling in confined spaces. The compact Bit-Check case organizes and protects the six bits for easy transport and storage.

How to use

Select the appropriate square bit size for the screw, insert the 1/4" hex shank into a compatible bit holder or screwdriver, and engage the screw head. Use steady axial pressure so the holding function keeps the screw on the bit while applying torque. Replace bits in the Bit-Check holder after use to keep them organized and protected.

Recommendations

For best results, match the bit size exactly to the screw profile and avoid excessive torque that may deform the screw or bit. Store bits in the provided Bit-Check to prevent loss and protect tips from damage.
