This is a 17 mm impact socket designed for use with a 1 inch (25.4 mm) square drive impact wrench. Its primary use is to remove and install 17 mm hex-headed fasteners in heavy-duty and industrial applications where high torque is applied by pneumatic, electric or hydraulic impact tools.

The socket is manufactured from heat-treated chromium‑molybdenum (Cr‑Mo) alloy steel, selected for its toughness under repeated impact loading. It has a matt black phosphate/oxide finish that provides corrosion resistance without the brittle plated coatings used on non‑impact sockets. The working end is a six‑point (6‑pt) hex profile to give maximum contact with nut and bolt flats, minimising rounding, and the socket accepts a 1" square drive with a standard detent hole for positive retention to a spring ball or retaining pin. The unit is produced to industry drive and dimensional conventions and is compatible with common DIN/ISO/BS square‑drive and socket standards (manufactured to meet the relevant DIN/ISO/BS drive and dimensional tolerances used for impact sockets and attachments).

Typical applications include heavy automotive and commercial vehicle maintenance, plant and machinery overhaul, rail maintenance, construction plant servicing and industrial maintenance where high torque is required. It is especially suitable in workshops and mobile service units using 1" drive torque multipliers and large air or electric impact wrenches for difficult fasteners.

Key benefits of this 17 mm 1" sqdr impact socket are its impact‑rated Cr‑Mo material offering superior toughness compared with chrome‑vanadium non‑impact types, the protective black phosphate finish that reduces corrosion in workshop environments, and the 6‑point profile which improves grip on fastener flats. Its 1" square drive ensures compatibility with a wide range of heavy‑duty impact tools and torque multipliers used in industrial settings.
