1/4 Inch Hex Double-Ended Flat Screwdriver Bit

When your work calls for two of the most common slotted fastener sizes, this double-ended insert bit puts both within a single flip of the tool. One end carries a 0.8 x 4 mm tip and the other a 1.0 x 6 mm tip, so you carry fewer loose pieces in your bit case while covering more of the flat head screws you encounter on cover plates, terminal strips, hinge hardware, and general maintenance.

Manufactured from S2 steel, every bit in the five-piece pack meets DIN 3126 and DIN 2351-3 dimensional standards for a precise fit in any 1/4 inch hex bit holder. The 32 mm overall length (approximately 1.26 inches) keeps the profile compact enough for quick-change chucks, ratcheting handles, and magnetic extensions without adding reach that invites wobble.

S2 steel is chosen for its balance of surface hardness and core toughness. It resists the rolling and chipping that sideline softer bits during power driving, yet it is not so brittle that it fractures under sudden torque spikes from an impact driver. The result is a flat tip that maintains its edge geometry across hundreds of drive cycles.

Each pack contains five identical pieces, giving tradesmen working through repetitive panel or electrical tasks the convenience of staging a fresh bit in every driver on the bench. When a tip finally shows wear, swap it out instantly and keep the line moving. Whether you drive screws by hand or with a cordless tool, the consistent shank dimensions deliver a secure, no-wobble seat that translates your effort directly into the fastener.
