Draper Expert Impact Hex. Socket Bit Set, 1/2" Sq. Dr. (8 Piece)

Handle the toughest hex fasteners with precision and confidence using the Draper Expert 8-Piece Impact Hexagonal Socket Bit Set (410/8/HEX/A) — a professional-grade set engineered for high-torque impact and drive applications across automotive, engineering, and industrial environments.

Integral Hex Bit Socket Design

Unlike bit-and-socket combinations that rely on separate components, each piece in this set features a socket with an integral hexagonal bit — a single forged unit that eliminates the weak points associated with two-part assemblies. The result is a more rigid, more reliable tool that transmits torque directly and efficiently, even under sustained impact loading.

Chrome Molybdenum — Hardened and Tempered

Every socket bit is forged from chrome molybdenum steel, then hardened and tempered for maximum toughness and fatigue resistance. Chrome moly is the benchmark material for impact-rated tooling, offering the strength to withstand repeated high-torque applications that would crack or deform standard chrome vanadium alternatives. The hardening and tempering process ensures each bit maintains its geometry and grip under the demanding loads typical of impact wrench use.

Black Phosphate Finish

A black phosphate finish on every bit delivers dependable corrosion and oxidation resistance, extending service life in workshop environments where exposure to moisture, oils, and cleaning fluids is routine. The non-reflective black finish also aids visibility and identification in low-light working conditions.

Secure Retention with Groove and Pin Design

Each bit incorporates a groove and two holes for a retaining ring and pin, providing positive retention on the drive tool and preventing accidental bit ejection during high-speed impact use — a critical safety and efficiency feature when working overhead or in confined spaces.

78mm Long Reach Body

At 78mm in length, these socket bits provide the reach needed to engage fasteners sunk deep into recessed housings, engine components, and structural assemblies — where a standard-depth socket or short bit simply cannot make adequate contact.

Comprehensive Size Range: 5mm to 19mm

With eight sizes covering the most commonly encountered metric hex fasteners, this set is ready for a wide range of applications — from precision component work with the 5mm and 6mm bits through to heavy-duty structural and drivetrain fasteners requiring the 17mm and 19mm variants.

Supplied in a Blow-Moulded Case

The complete set arrives in a sturdy blow-moulded case with display sleeve, with individual moulded recesses for each bit to keep everything organised, protected during transit, and easy to inventory at the end of a job.
