1/4 Inch Robertson Square Drive Screwdriver Bits 25 mm ROB1

This 3-pack of Teng Tools ROB1 Robertson square drive bits gives tradesmen a reliable supply of the size they reach for most. Each bit features a 1/4 inch hex shank that fits standard quick-change chucks and bit holders, so there is no need for adapters when swapping between a drill and an impact driver.

At 25 mm (1.0 in) overall, the compact profile keeps the bit close to the chuck for precise control. That short reach is especially useful when driving fasteners in tight quarters — inside electrical boxes, behind cabinetry or along closely spaced framing members — where a longer bit would force an awkward angle.

Robertson fasteners are a staple in decking, framing, cabinetry and general construction because the square recess grips the bit and resists cam-out. By stocking individual 3-packs in the exact size your projects demand, you avoid paying for mixed sets loaded with sizes you never touch. Toss a spare in your tool pouch, keep one in the truck and mount one in your driver so you are always ready to work.

Whether you are running deck screw bits all day or assembling cabinets, these ROB1 bits deliver a positive fit that makes every drive count.
