Product Overview
The W07027 (Product Code TKC34-32) 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 where medium to high torque is required.
The set includes 19 hex (6-point) metric sockets (8-32 mm) for high-torque work, 6 bi-hex (12-point) sockets (10-19 mm) for fast engagement in tight spaces, 2 spark plug sockets (16 / 21 mm), 1 quick-release ratchet wrench, 2 extension bars (125 / 250 mm), 1 universal joint and 1 adapter (10 mm F × 12.5 mm M).
Key advantage: The dual-profile configuration lets technicians choose the right grip for each job — hex sockets give maximum contact and torque capacity for tight or seized fasteners, while bi-hex sockets engage every 30° instead of 60°, making them twice as fast to align in crowded engine bays. Add 2 dedicated spark plug sockets with rubber inserts that protect the ceramic body, an adapter for running 3/8″ sockets on the 1/2″ drive, and a universal joint plus dual extensions for angled and deep-recess access — five working conditions solved in one kit.
Sockets are forged from premium chrome-vanadium (CR-V) steel, hardened and mirror-polished with chrome plating. At 4.46 kg per set with 5 sets per carton, the kit combines solid content with efficient packing — an excellent SKU for automotive channels, industrial buyers and hardware wholesalers.

FAQ
Q1: What is your MOQ and lead time?
A: 1 carton (5 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: Why include both 6-point and 12-point sockets, and when should each be used?
A: Each has advantages the other cannot replace.
6-point (hex) sockets contact all six flats of the nut, giving a larger contact area, firmer grip and higher torque capacity while effectively preventing rounded corners. Use them for high-torque fastening, seized bolts and slightly worn nuts.
12-point (bi-hex) sockets engage the fastener every 30° instead of every 60°, making them twice as fast to align in crowded areas where wrench swing is restricted — ideal for detailed engine bay work.
This kit provides 19 hex sockets covering the full 8-32 mm range plus 6 bi-hex sockets in 10/12/13/14/17/19 mm — exactly the sizes most used under the hood. Our recommendation: use 6-point whenever possible, and switch to 12-point when space is tight.
Q3: How do spark plug sockets differ from regular sockets, and what vehicles do 16/21 mm fit?
A: A spark plug socket has a built-in rubber insert that grips the ceramic body of the plug, preventing it from dropping and cracking during removal or installation. It is also deeper to accommodate the full length of the plug — features a standard socket cannot replicate.
16 mm (5/8″) fits the majority of modern passenger cars (most current Japanese, German and American models), while 21 mm (13/16″) suits older vehicles, some American models, motorcycles, lawn mowers and small engines. Together they cover the vast majority of common vehicles and power equipment.
Q4: What is included, and how is the adapter used?
A: The set contains 19 hex sockets (8-32 mm), 6 bi-hex sockets (10/12/13/14/17/19 mm), 2 spark plug sockets (16/21 mm), 1 quick-release ratchet wrench, 2 extension bars (125/250 mm), 1 universal joint and 1 adapter.
The adapter (10 mm F × 12.5 mm M) has a 3/8″ female square on one end and a 1/2″ male square on the other — fit it to the 1/2″ ratchet and you can use 3/8″ sockets, giving cross-standard versatility so existing 3/8″ sockets remain useful without duplicate purchases.
The 250 mm long extension reaches deep into the engine bay and underbody, while the universal joint handles angled and obstructed fasteners — a genuinely complete drive system.
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 sizes and profile mix can be freely adjusted for your market (6-point/12-point ratio, metric or SAE, more or fewer pieces, added deep sockets or 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 compact 4.46 kg configuration with 5 sets per carton suits both bulk industrial procurement for repair chains, factories and vocational schools (with lower freight cost) 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.
