Screwdriver bit set KWB 128240 — 5 pcs Torx bits T3 T4 T5 T6 T8, 28 mm

Screwdriver bit set KWB 128240 contains five Torx bits (T3, T4, T5, T6, T8) each 28 mm long, intended for precision fastening of small Torx screws in electronics, consumer appliances and hobby projects. The bits have a 4 mm hexagon shank and come on a practical fastening strip with a satin-finished surface for easy handling and storage.

Advantages

The bits are made from high-quality TQ 60 steel for durability and wear resistance. Extra-long 28 mm tips allow access to screws in recessed or hard-to-reach locations. The uniform 4 mm hex shank fits standard bit holders and power drivers, and the fastening strip keeps the set organised for transport and storage.

How to use

Select the Torx size that matches the screw head, insert the 4 mm hex shank into a compatible bit holder or power driver, and engage the screw with steady, controlled torque. Use the extra-long 28 mm length to reach recessed screws; ensure the bit is seated fully in the screw head to avoid cam‑out and damage.

Recommendations

For best results, pair the bits with a compatible bit holder or precision screwdriver, apply moderate torque appropriate to small electronics fasteners, and store the bits on their fastening strip to prevent loss and protect the tips.
