38-Piece 10mm Metric Socket Wrench Set Kit

Product Overview

The W07140 (Product Code TKT2-38 / TK-016) is a 38-piece tool set with a dual-drive system, designed for automotive repair, appliance servicing, machinery assembly and home DIY.

The kit pairs a 10 mm (3/8″) socket system with a 6.3 mm (1/4″) bit system: 15 hex metric sockets (6-22 mm) with a 3/8″ ratchet wrench handle medium to high torque fastening, while 15 long 25 mm screwdriver bits covering five drive types, together with a 1/4″ bit handle and bit adapter, take care of precision screws. Add 3 hex keys, 150 mm long nose pliers and a 150 mm adjustable wrench, and you have driving, wrenching and gripping all in one kit.

Key highlights: Sockets span a broad 6-22 mm range; the 15 bits cover Phillips, Slotted, Hex, Torx and Square drive types, handling fasteners on appliances, furniture, car interiors and electronics. The 6.3 mm bit adapter lets you mount bits into the ratchet wrench for ratchet-driven screwdriving — a major time-saver in confined spaces.

All tools are forged from premium chrome-vanadium (CR-V) steel and hardened, with 6-point socket profiles that grip flat on nut faces to prevent slipping and rounding. At just 1.92 kg per set with 12 sets per carton, it is light, portable and efficient to ship — an excellent value SKU for retail chains, hardware stores, e-commerce platforms and gift channels.

2. Dual-Drive Configuration — Two Systems in One Kit — 3/8″ sockets for medium-to-high torque and 1/4″ bits for precision screws, plus a bit adapter enabling ratchet-driven screwdriving. Far more coverage and flexibility than single-system kits at the same price point, driving strong end-user reviews.

FAQ

Q1: What is your MOQ and lead time?
A: 1 carton (12 sets) for stock items, shipped within 7-15 days. For custom logo and packaging orders, MOQ is 500 sets with a lead time of about 30-45 days. We accept T/T (30% deposit + 70% balance), L/C at sight, Trade Assurance, Western Union and PayPal (small sample orders).

Q2: Why does this set have two drive sizes, and how do they work together?
A: The kit uses a dual-drive system. The 10 mm (3/8″) socket system with the ratchet wrench handles medium-to-high torque bolts and nuts, while the 6.3 mm (1/4″) bit system with the bit handle takes care of precision screws.
The two connect via the 6.3 mm bit adapter — insert a bit into the adapter, mount it on the 3/8″ ratchet, and you can drive screws with the ratchet, working continuously in tight spaces. This is the most practical design feature of the set.

Q3: What is included in the 38 pieces, and are the bits sufficient?
A: The kit contains 15 sockets (6-22 mm), 1 × 3/8″ ratchet wrench, 15 × 25 mm long bits, 1 bit adapter, 1 × 1/4″ bit handle, 3 hex keys (1.5/2/2.5 mm), 1 × 150 mm long nose pliers and 1 × 150 mm adjustable wrench.
The 15 bits cover Phillips PH0/1/2, Slotted SL3/4/5, Hex H3/4/5, Torx T10/15/20 and Square S1/2/3 — five drive types that handle the vast majority of screws on appliances, furniture, car interiors, electronics and toys, which is more than sufficient for everyday use.

Q4: What material are the sockets and bits? Will they slip or round off fasteners?
A: All are forged from premium chrome-vanadium (CR-V) steel, quenched and tempered — sockets to HRC 44-52 and bits to HRC 58-62 — for excellent torsion and wear resistance. 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 older, slightly worn fasteners. Always select the size that exactly matches the fastener. Material certificates or SGS/BV third-party testing can be arranged.

Q5: Can the logo, contents and packaging be customized?
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 and bit combinations can be freely adjusted for your market (metric, SAE or mixed, with more or fewer pieces). Packaging options include blow-molded case, clear PP carry case, metal box, canvas bag and gift box, with custom color box printing, multilingual manuals, barcodes and hang tags.
At only 1.92 kg with a compact footprint, it works very well as an e-commerce best seller, retail shelf item and corporate promotional gift, with low shipping cost as a bonus. Samples can be sent first, with the sample charge refunded against a bulk order.
