Makita P-05941 teräadapteri 1/2 tuuman neliökäyttö 1/4 tuuman kuusikantavarteen

On a busy construction site, a mechanic reaches for an impact wrench to drive a long structural screw. The wrench has a 1/2" square drive, but the screw needs a 1/4" hex bit. The Makita P-05941 bridges that gap instantly. It locks onto the square drive with a ball detent and holds the hex bit securely with a C-ring, so the bit stays put under high torque. No hunting for a dedicated hex driver, no lost time.

Key specifications

• Input drive: 1/2" square (12.7 mm)
• Output drive: 1/4" hex shank (6.35 mm)
• Material: Impact-grade steel with black phosphate coating
• Bit retention: C-ring
• Tool retention: Ball detent
• Overall length: 50 mm
• Maximum diameter: 25 mm

Why choose it

This adapter is built for impact use. The steel body withstands high torque, and the black phosphate finish resists corrosion. The C-ring holds hex bits firmly, while the ball detent keeps the adapter from slipping off the square drive. You get a reliable connection between two common drive sizes without extra bulk.

Ideal use cases

• Driving hex-shank screws with a 1/2" impact wrench
• Using 1/4" hex drill bits in a 1/2" ratchet
• Adapting power tools to accept common screwdriver bits
• Quick bit changes in high-torque applications

Good to know

The adapter is 50 mm long and 25 mm at its widest point. It is sold as a single piece. No bits are included.
