Why this one
Secure magnetic retention
The built-in magnet grips 1/4 inch hex shank screwdriver bits firmly, preventing them from falling out during overhead work, awkward angles, or sustained impact driving.
Impact-rated construction
Designed to withstand the repeated high-torque jolts an impact driver delivers, this holder is built for the demands of daily professional use.
Compact 60 mm length
At 60 mm (approximately 2.4 in), the holder adds just enough reach to clear obstructions without sacrificing the short, controlled feel that precise fastening work demands.
Universal 1/4 inch hex drive
The 1/4 inch hex shank seats directly into any impact driver, drill, or quick-change chuck that accepts that standard.
Easy bit changes on the go
Swap between Phillips, Torx, slotted, or square-drive bits in seconds without setting down the driver.
Read the full description
When every fastener on the punch list matters, the tool that sits between your driver and the bit has to do its job without a second thought. This Teng Tools 1/4 inch hex drive holder does exactly that: a magnet inside the barrel locks the bit in place, and the impact-rated body absorbs the punishment a modern brushless driver dishes out.
Measuring 60 mm (about 2.4 in) in overall length, the holder threads into confined spaces — think joist bays, panel boxes, and dashboard cavities — while still keeping you close enough to the work for precise depth control. The 1/4 inch hex shank slides into any compatible drill or quick-change chuck, so one holder covers every cordless tool on your truck.
Swap bits on the fly: pull one out, drop the next one in, and the magnet seats it. No collets, no set screws, no wasted motion. Phillips, Torx, slotted, Robertson — any standard 1/4 inch hex shank tip locks right in.
Teng Tools accessories are designed with working tradesmen in mind. If your current holder slips bits at the worst possible moment or rattles itself loose mid-drive, this is the upgrade that puts the problem behind you.
