5.5 mm Flat Slotted Screwdriver Bit

When the job calls for a slotted fastener and your last good tip is showing wear, this 2-pack puts a matched pair of 5.5 mm bits back in your pouch without forcing you to buy an entire assortment.

Each piece measures 70 mm (2.8 in) from end to end, keeping the overall profile compact enough for access inside cramped enclosures, electrical panels and equipment housings. The 1/4 inch hex shank is the universal standard, so the tips seat firmly in cordless drivers, hand-held ratchet adapters and precision handles alike.

The 5.5 mm width handles the larger slotted fasteners common in HVAC ductwork, automotive interior trim and industrial control panels. A correct width-to-thickness match reduces lateral play in the slot, lowers the risk of cam-out and protects both the fastener and the surrounding finish from cosmetic damage.

Sold as a 2-pack, these bits give you one to run and one to carry. When the active tip dulls, swap it out in seconds and keep moving. Restocking by individual size means you track exactly what you consume and replenish only what you need, an approach that saves money across shops managing dozens of tool bags.
