Draper HI-TORQ® Impact Socket Set, 3/8" & 1/2" Sq. Dr. (32 Piece)

Equip your workshop with one of the most comprehensive impact socket sets available at this price point — the Draper HI-TORQ® 32-Piece Impact Socket Set (409/32/MM). Covering both 3/8" and 1/2" square drive in standard and deep configurations, this is a true all-in-one impact socket solution for professional technicians, automotive workshops, and serious home mechanics.

A Complete Impact Socket Solution

With 32 pieces spanning two drive sizes, standard and deep socket formats, extension bars, and a drive adaptor, the 409/32/MM is designed to eliminate the need for multiple individual socket purchases. Whether you're torquing cylinder head bolts, removing suspension fasteners, working on exhaust systems, or tackling drivetrain components, this set has the size, reach, and drive configuration to get the job done.

HI-TORQ® 6-Point Impact Sockets

Every socket in this set features Draper's HI-TORQ® 6-point geometry, engineered to maximise contact with the flat faces of a fastener rather than its corners. Under the high-torque, high-frequency pulses of air and electric impact wrenches, this design dramatically reduces the risk of rounding off fastener heads — protecting both the fastener and the socket during heavy-duty use.

Chrome Molybdenum — Hardened, Tempered and Chemically Blackened

All sockets are forged from chrome molybdenum steel, then hardened and tempered to withstand the repeated shock loading delivered by impact wrenches. Unlike chrome vanadium sockets — which are not rated for impact use and can shatter under impact loads — chrome moly provides the toughness, ductility, and fatigue resistance required for safe, reliable impact tool operation.

A chemical blackening finish on every socket provides robust corrosion protection, extending service life in demanding workshop environments and giving the set a clean, professional appearance that distinguishes impact-rated tooling from standard drive sockets at a glance.

Spring-Loaded Ball Retention

Each socket incorporates a hole for an accessory spring-loaded ball, ensuring positive retention on the drive tool during use — a critical feature when working at speed with an impact wrench, particularly in overhead or confined applications where dropped sockets cause delays and potential damage.

Dual Drive — 3/8" and 1/2" Square Drive

By combining both 3/8" and 1/2" square drive sockets in a single set, the 409/32/MM provides the versatility to work across a wide spectrum of torque requirements — from lighter-duty 3/8" drive applications to the high-torque demands of 1/2" drive work on wheel nuts, suspension bolts, and engine components.

A 1/2"(F) x 3/8"(M) adaptor is included, allowing 3/8" drive sockets to be used on a 1/2" drive impact wrench and vice versa, further maximising the utility of the set.

Standard and Deep Socket Formats

The inclusion of 10 deep sockets in 1/2" drive makes this set particularly valuable for applications involving extended bolts, threaded studs, or fasteners recessed deep within housings — common on suspension assemblies, exhaust systems, and engine components where standard-depth sockets cannot achieve full engagement.

Extension Bars Included

Both a 3/8" and a 1/2" 75mm extension bar are included, providing additional reach for fasteners in confined or recessed locations without the need for separate accessory purchases.

Important Safety Note

Only impact-rated sockets and accessories should be used with air or electric powered wrenches. Never use standard silver chrome vanadium steel sockets with impact tools — they are not designed to absorb impact shock and can shatter under load, causing serious personal injury.
