The 41mm Hi‑Torq 6 Point Deep Impact Socket 1" Dr is a heavy‑duty impact socket designed for use with 1‑inch square‑drive impact wrenches and air or battery breakers. Its primary use is the safe removal and installation of large hex fasteners and wheel nuts where a deep reach and high torque capacity are required, for example on HGV wheels, agricultural machinery and heavy plant.

Manufactured from chrome‑molybdenum (Cr‑Mo) alloy steel and heat‑treated for toughness, this socket resists the shock loading produced by impact tools. The surface is finished with a black phosphate/oxide coating to reduce corrosion and surface marking while maintaining a non‑slip handling profile. The socket follows recognised DIN/ISO/BS dimensional and performance practices for impact sockets and is supplied with a 6‑point (hex) internal profile to concentrate drive on the flats of the fastener rather than the corners, reducing rounding on high‑torque applications. The drive connection is a 1" square drive with a detent/recess for retaining pins or clips where required; thread type is not applicable for this style of socket.

The deep length gives additional reach to locate nuts recessed on studs or over brake drums, making it suitable for automotive, commercial vehicle maintenance, plant engineering, construction and agricultural servicing. The 6‑point geometry is particularly beneficial on stubborn or slightly corroded fasteners, providing better contact and torque transfer than 12‑point designs in heavy‑duty scenarios.

Key benefits include enhanced impact toughness from the Cr‑Mo construction, improved corrosion resistance from the black phosphate finish, and strong torque transmission without damaging fastener faces due to the 6‑point profile. Compatibility with 1" square‑drive impact wrenches and standard retaining pin systems makes it straightforward to integrate into workshop toolsets and mobile service kits.
