This is a 24 mm impact socket with a 1" (25.4 mm) square drive, intended for use with heavy-duty impact wrenches, pneumatic or electric impact guns, breaker bars and torque multipliers. Its primary use is the rapid removal and installation of hexagonal fasteners on large plant, commercial vehicles, industrial machinery and structural assemblies where high torque and shock loading are routine.

The socket is manufactured from chrome‑molybdenum (Cr‑Mo) alloy steel and is heat treated to deliver a tough core and a durable working surface suitable for impact applications. The internal profile is a six‑point (6PT) hex, which locates on the flats of a nut or bolt to reduce rounding under high torque. The female end accepts a 1" square drive; there are no threaded interfaces on the socket itself. The external finish is a black phosphate/oxide treatment that provides corrosion resistance and reduces the risk of chipping under repeated impact use.

The dimensions and drive interface conform to the recognised DIN/ISO/BS socket standards for interchangeable hand and power tool fittings, ensuring compatibility with industry‑standard 1" drive impact tools and extensions. As an impact-rated tool it differs from chrome‑vanadium hand sockets by offering greater toughness and resistance to shock fracture when used with impact wrenches.

Typical applications include heavy vehicle wheel and hub work, plant maintenance, railway and marine maintenance, construction equipment servicing and industrial assembly where large metric fasteners (M18 and above, depending on thread form) are common. The 6‑point geometry and Cr‑Mo construction make it particularly suitable where repeated high torque cycles are required and where corrosion resistance and long service life are important.

Key benefits are the socket's resistance to impact fracture thanks to Cr‑Mo material and heat treatment, compatibility with standard 1" drive impact tools, and a corrosion‑resistant black phosphate finish for extended service life in workshop and outdoor environments. Duchy Fasteners stocks this 24 mm impact socket as an individual item and as part of metric impact sets; sizes across the metric range and trade pack options are available – contact Duchy Fasteners for current stock levels and pack quantities.
