Frequently Asked Questions

Q: What is S2 steel and why does it matter for screwdriver bits?

A: S2 is a specially hardened tool steel known for its high impact resistance, toughness, and ability to maintain a sharp, precise tip under heavy torque. S2 steel Torx bits outlast standard chrome-vanadium bits and are far less likely to strip or deform under demanding use conditions — making this set ideal for both DIY enthusiasts and professionals.

Q: Will these Torx bits fit my existing screwdriver or drill?

A: Yes. The 1/4" (6.35mm) hex shank is an industry-standard size that fits the vast majority of power drills, electric screwdrivers, manual bit holders, and impact drivers available on the market today. Simply insert the bit into any standard 1/4" chuck or bit holder and you're ready to go.

Q: Are the bits truly magnetic? How strong is the magnetism?

A: Yes — each bit in this set is equipped with strong built-in magnetism at the tip. The magnetic force is sufficient to hold Torx screws firmly during installation and removal, which is especially useful when working in hard-to-reach areas where dropped screws can be a real problem.

Q: What sizes are included in the set?

A: This 7-piece set includes T10, T15, T20, T25, T27, T30, and T40 Torx bits — covering the most commonly encountered Torx fastener sizes in automotive, electronics, appliances, and general household repairs.
