screw bits

These sets include the common drive heads used for electronics and general repair: Torx (including 5‑point/Torx Star/pentalobe variants), Phillips, slotted (flat), square (Robertson), hex/socket, tri‑wing, triangle, U‑shape, and pentagonal bits.

Many kits include dedicated storage: compact boxes or sleeve cases (one is described as a red sleeve), and more durable cases with labeled slots or removable organizer strips to keep bits neat and portable.

Durability features mentioned include hardened and tempered S2/CR‑V steel construction, high‑temperature forging followed by low‑temperature quenching for S2 alloy bits, blackened phosphate or coated finishes, and in drill bits M35 cobalt or titanium coatings for greater hardness and wear resistance.

Yes — several kits include magnetic bit holders or magnetic designs to hold screws in place, and some also include a magnetizer/demagnetizer to control bit magnetism.

Precision sets call out ergonomic, non‑slip handles with rubber coatings, diamond‑pattern non‑slip grips, optimized leverage for tight or hidden screws, and a 360° swivel top for comfortable, precise control.
