Draper Impact Socket Adaptor Set (8 Piece)

Maximise the versatility of your existing impact socket collection with the Draper 8-Piece Impact Socket Adaptor Set (ISAS/8) — a comprehensive set of drive adaptors engineered to bridge every common square drive size, from 1/4" right through to 1", in both step-up and step-down configurations.

The Complete Drive Conversion Solution

Every workshop accumulates sockets and drive tools across multiple drive sizes over time. Without the right adaptor, a perfectly good socket becomes unusable simply because the drive size doesn't match the tool in hand. The ISAS/8 eliminates this frustration entirely, providing all eight key drive conversion combinations in a single set — covering 1/4", 3/8", 1/2", 3/4" and 1" square drives in both male and female pairings.

Whether you need to run a 1/4" drive socket on a 3/8" impact wrench, step up from a 1/2" drive tool to a 3/4" drive socket, or convert in any direction across the full drive range, this set has the adaptor for the job.

Impact Rated for Air and Electric Tools

Every adaptor in this set is fully rated for use with electric and pneumatic impact wrenches, making them a safe and reliable choice for high-torque, high-frequency impact applications. These are not standard hand-tool adaptors — they are purpose-built to absorb and transmit the shock loads generated by impact tooling without failure, giving you confidence across the full 1/4" to 1" drive range.

Chrome Molybdenum — Hardened, Tempered and Black Phosphate Finished

All eight adaptors are forged from chrome molybdenum steel, then hardened and tempered to withstand the rigours of repeated impact use. A black phosphate finish provides dependable corrosion and oxidation protection, extending service life in workshop environments where exposure to moisture, oils, and brake dust is routine. The non-reflective black finish also makes it easy to distinguish these impact-rated adaptors from standard chrome accessories at a glance.

Step-Up and Step-Down — Every Combination Covered

The set covers all common adjacent and cross-drive conversions in both directions, making it genuinely comprehensive rather than a partial solution:

• 3/8"(F) × 1/4"(M) — Step down from 3/8" tool to 1/4" socket
• 1/4"(F) × 3/8"(M) — Step up from 1/4" tool to 3/8" socket
• 3/8"(F) × 1/2"(M) — Step down from 3/8" tool to... wait — step up from 3/8" tool to 1/2" socket
• 1/2"(F) × 3/8"(M) — Step down from 1/2" tool to 3/8" socket
• 1/2"(F) × 3/4"(M) — Step up from 1/2" tool to 3/4" socket
• 3/4"(F) × 1/2"(M) — Step down from 3/4" tool to 1/2" socket
• 3/4"(F) × 1"(M) — Step up from 3/4" tool to 1" socket
• 1"(F) × 3/4"(M) — Step down from 1" tool to 3/4" socket

Supplied in a Blow-Moulded Storage Case

The full set arrives in a sturdy blow-moulded case with individual recesses for each adaptor, keeping everything organised, protected during transit, and easy to locate quickly during a busy working day.
