Why this one
Matched tip width for clean engagement
Each bit delivers a 5.5 mm wide flat head contact surface designed to fill the fastener slot completely.
Standard 50 mm overall length (approximately 2.0 in)
This compact insert-style length seats securely in a quick-release chuck or manual screwdriver handle without adding unnecessary reach that could flex under torque.
Universal 1/4 inch shank interface
The shank drops directly into any 1/4 inch hex receiver, magnetic sleeve, or power tool chuck.
Sold in a convenient three-pack
Slotted tips are consumables that wear with use, and a three-pack ensures you are never caught without a fresh replacement on a live job.
Organized and ready to deploy
Individual bits store easily in standard bit cases, magnetic rail systems, and divided drawer inserts.
Read the full description
A 5.5 mm slotted fastener deserves a tip that fills the slot from edge to edge. This Teng Tools three-pack delivers that precise fit in a 1/4 inch shank format compatible with every standard drill, driver, and manual bit holder.
Each bit measures 50 mm (approximately 2.0 in) in overall length — the industry-standard insert dimension that balances compact clearance with secure chuck engagement. Whether you are working inside an electrical panel or reaching across a workbench, the length keeps things manageable without sacrificing grip in the holder.
The 1/4 inch hex shank is the universal attachment point across cordless drills, impact drivers, and hand-held carriers. One pack serves every tool in the lineup, and the three-count format keeps a spare close at hand for the inevitable moment a tip wears out.
Slotted hardware remains common across electrical, HVAC, appliance, and general maintenance trades. Having the right tip width on the truck is a small investment that pays off every time you avoid a stripped slot or a return trip to the supply house. Add this three-pack to your Teng Tools loadout and keep the exact size you need within arm's reach.
