Product Overview
The W07025 (Product Code TKT7-32G / TK-165) 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 kit follows a “sockets first, accessories lean” value philosophy — 27 sockets plus 5 drive accessories — concentrating the budget on the parts technicians use and wear out most, delivering greater real-world value to the end user.
It includes 19 hex (6-point) metric sockets (8-32 mm) covering the full size range, 8 bi-hex (12-point) sockets (10-21 mm) in the engine bay’s most-used sizes, 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 8 bi-hex sockets are what set this kit apart — more than most comparable sets, covering 10/12/13/14/17/18/19/21 mm, precisely the size band most needed in crowded engine bays. Bi-hex sockets engage every 30° instead of 60°, making them twice as fast to align, and together with the 19 hex sockets’ torque advantage they form a perfectly complementary pair.
Sockets are forged from premium chrome-vanadium (CR-V) steel, hardened and mirror-polished with chrome plating. 4.70 kg per set, 4 sets per carton.

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: Why include both 6-point and 12-point sockets, and what is the advantage of 8 bi-hex pieces?
A: Each profile 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 — best for high-torque fastening, seized bolts and worn nuts.
12-point (bi-hex) sockets engage every 30° instead of every 60°, making them twice as fast to align where wrench swing is restricted — ideal for detailed engine bay work.
This kit provides 8 bi-hex sockets (10/12/13/14/17/18/19/21 mm), more than the 4-6 found in typical sets, covering virtually every high-frequency engine bay size. In practice this means technicians rarely have to swap back to a hex socket mid-job in confined spaces, significantly improving workflow continuity. Our recommendation: use 6-point whenever possible, and switch to 12-point when space is tight.
Q3: What is included, and how is the adapter used?
A: The set contains 19 hex sockets (8-32 mm), 8 bi-hex sockets (10/12/13/14/17/18/19/21 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.
Q4: What material are the sockets, and should I choose 1/2″ or 3/8″ drive?
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 mirror-polished chrome finish wipes clean of grease and resists rust. Material certificates or SGS/BV third-party testing can be arranged.
On drive size: 1/2″ (12.5 mm) is the heavy-duty standard, with a thick square drive for wheel bolts, suspension components, engine mounts, gearboxes, trucks and construction machinery, while 3/8″ (10 mm) is the mid-range standard for engine bay internals and small machinery. Because this kit includes the adapter, it covers both standards from a single 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 spark plug 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 substantial 4.70 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.
