Key Features & Specifications
-
Drive Size: Heavy-duty 1-inch square drive compatible with large impact guns, torque multipliers, and commercial workshop gear.

6-Point Hex Profile: Precision-machined 6-point socket geometry grips the flat sides of fasteners rather than the corners, preventing slip and protecting stubborn, rusted, or high-torque bolts from rounding off.
-
Extensive Size Range (21-Piece Set): Covers a wide metric spectrum from 30mm up to 80mm, making it ideal for large axle nuts, commercial truck suspension components, and heavy industrial machinery.
-
Impact-Grade Construction: Forged from high-strength, heat-treated chrome-molybdenum (Cr-Mo) steel designed to absorb and withstand continuous high-impact shock loads.
-
High-Visibility Size Markings: Large, permanent laser-etched and roll-stamped size markings on each socket for rapid identification in busy workshop bays or dim service pits.
-
Heavy-Duty Storage Case: Supplied in a rugged, blow-moulded metal or heavy plastic storage/carrying case equipped with secure latches and carrying handles for easy transport between job sites.
