Klein Tools 409-660 85160 #0 Square Tip Screwdriver

#0 Square Tip Screwdriver

The Klein Tools 409-660 85160 is a hand screwdriver built for driving #0 square-recess fasteners. Its heat-treated vanadium shank and black oxide tip resist wear on the job site. The plastic handle is shaped to resist slippage even when hands are oily or wet. It suits electricians and maintenance technicians who regularly encounter Robertson-style screws.

Sustained driving comfort and tip durability

The round shank is heat-treated and tempered to maintain hardness during repeated torque cycles without rounding off. Black oxide finish on the shank and tip reduces corrosion when the tool is exposed to moisture or chemicals. The handle material resists oil, gas and water, so grip remains consistent throughout a long shift. The tip geometry holds the fastener securely to limit cam-out under load.

Build quality and daily handling

A black oxide vanadium shank provides a hard wearing surface that withstands impact and twisting forces. The plastic handle is moulded to resist slippage and does not degrade when wiped with solvents or fuel. Black oxide coating on the shank adds a layer of rust protection for storage in damp tool bags. The tool is sold as a single unit ready for immediate use.
