Frequently Asked Questions

Q: What bit types are included in this 30-piece impact screwdriver bit set?

A: The set includes a variety of Pozidriv, Hex (Allen), and Star (Torx-style) driver bits, all featuring a 1/4" magnetic hex shank. This multi-type assortment covers the most common fastener heads found in automotive, construction, and household applications.

Q: Are these bits compatible with standard impact drivers?

A: Yes. The 1/4" magnetic hex shank is the industry-standard size for impact drivers and drills. The D2 alloy steel construction is specifically suited to withstand the high-torque demands of impact driving without premature wear or breakage.

Q: What makes the D2 alloy steel better than standard screwdriver bits?

A: D2 alloy steel is a high-carbon, high-chromium tool steel known for its superior hardness, wear resistance, and toughness. Compared to standard S2 or chrome-vanadium bits, D2 steel holds its edge longer under repeated impact, making it ideal for heavy-duty or frequent use. The manganese phosphate coating adds an additional layer of rust resistance for lasting performance.

Q: How long are the bits in this set?

A: Each bit measures 2 inches (50mm) in length, which is the most widely compatible size for use with standard bit holders, extensions, and drill chucks.
