Product Overview
The W07021 (Product Code TKT7-32B / TK-088) is a 32-piece metric socket set built on a 12.5 mm (1/2″) heavy-duty drive system, designed for automotive repair, truck and construction equipment servicing, and industrial maintenance — wherever medium to high torque is required.
The 1/2″ drive is the workhorse standard in automotive and industrial workshops. Its substantially thicker square drive delivers far greater torque capacity than a 3/8″ system, making light work of wheel bolts, suspension components, engine mounts and gearbox fasteners.
The set includes 22 hex metric sockets (8-32 mm) covering the full size range without gaps, 2 spark plug sockets (16 / 21 mm), 1 quick-release ratchet wrench, 3 extension bars (75 / 125 / 250 mm), 1 universal joint, 1 L-type handle, 1 × 52 mm screwdriver bit and 1 adapter (10 mm F × 12.5 mm M) — a complete solution for deep-recess, angled, confined, high-torque and cross-drive applications.
Key highlights: The adapter (3/8″ female × 1/2″ male) lets you run 3/8″ sockets on the 1/2″ drive, dramatically extending compatibility. The 250 mm long extension reaches deep into engine bays and under vehicles. The L-type handle provides high breaking torque while protecting the ratchet mechanism.
Sockets are forged from premium chrome-vanadium (CR-V) steel and hardened, with 6-point profiles that grip flat on nut faces to prevent slipping and rounding. At 5.36 kg per set with 4 sets per carton, the kit offers genuine professional substance — an excellent SKU for automotive channels, industrial buyers, hardware wholesalers and premium gift programs.

FAQ
Q1: What is your MOQ and lead time?
A: 1 carton (4 sets) for stock items, shipped within 15-20 days. For custom logo and tool case orders, MOQ is 300 sets with a lead time of about 35-50 days. We accept T/T (30% deposit + 70% balance), L/C at sight, Trade Assurance, Western Union and PayPal (small sample orders).
Q2: What is the difference between 1/2″ and 3/8″ drive, and which should I choose?
A: 1/2″ (12.5 mm) is the heavy-duty standard — a thicker square drive with significantly higher torque capacity, suited to wheel bolts, suspension components, engine mounts, gearboxes, trucks and construction equipment. 3/8″ (10 mm) is the mid-range standard, better for engine bay internals, interior trim and small machinery at lower torque.
This set also includes a 10 mm F × 12.5 mm M adapter, which lets you run your existing 3/8″ sockets on the 1/2″ drive — giving cross-standard versatility and maximizing the value of tools you already own.
Q3: What is included, and how are the adapter and L-handle used?
A: The set contains 22 sockets (8-32 mm), 2 spark plug sockets (16/21 mm), 1 quick-release ratchet, 3 extension bars (75/125/250 mm), 1 universal joint, 1 L-type handle, 1 adapter and 1 × 52 mm screwdriver bit.
Adapter (10 mm F × 12.5 mm M): one end is a 3/8″ female square, the other a 1/2″ male square — fit it to the 1/2″ ratchet and you can use 3/8″ sockets.
L-type handle: solid construction that withstands far higher torque than a ratchet, specifically for breaking loose seized bolts; it also works as a fast-spin handle. Best practice is to break loose with the L-handle and remove with the ratchet — efficient work with a longer tool life.
Q4: What material are the sockets? Is 8-32 mm enough coverage? Will they round off nuts?
A: Sockets are forged from premium chrome-vanadium (CR-V) steel, quenched and tempered to HRC 44-52, with torsional strength meeting DIN/ISO standards — fully capable of heavy-duty work.
The 22 sockets span 8-32 mm continuously (omitting only the rarely used 25, 29 and 31 mm), covering everything from small engine bolts to large wheel nuts and truck chassis fasteners — the ideal size range for a 1/2″ system.
The 6-point socket profile contacts the nut flats over a larger area than a 12-point design, effectively preventing slipping and rounded corners, which is especially valuable on worn or corroded fasteners. Material certificates or SGS/BV third-party testing can be arranged.
Q5: Can the logo, contents and packaging be customized? Is it suitable for industrial procurement or gifting?
A: Absolutely. We offer laser engraving or steel stamping of your logo on the sockets, ratchet and case, plus custom handle and case colors. Socket combinations can be freely adjusted for your market (metric, SAE or mixed, with more or fewer pieces, or added deep sockets and breaker bars). Packaging options include blow-molded case, aluminum case, metal tool box, canvas roll and EVA-lined gift box, with custom color box printing, multilingual manuals, barcodes and hang tags.
The substantial 5.36 kg configuration suits both bulk industrial procurement for repair chains, factories and vocational schools and premium gifting for car brands, motor oil brands and auto parts chains. Samples can be sent first, with the sample charge refunded against a bulk order.
