·【Complete 10-Piece 3/8" Drive Metric Shallow Socket Set】This 3/8" Drive Socket Set includes 10-piece metric shallow sockets in the most commonly used sizes: 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm,19mm, paired with an EVA foam case. Designed for tight spaces, it’s ideal for various work scenarios including automotive repair, small machinery maintenance, motorcycle and bicycle refurbishment—covers all your basic and daily needs!

·【Premium Material and Coating for Maximum Durability】All sockets are made from hardened Chrome-Vanadium (Cr-V) steel, then heat treated for high torque strength and finished with a double-layer polished finish—far more wear-resistant, rust-resistant and scratch-proof than ordinary coatings. This mirror-like plating is easy to clean and stands up to heavy daily use in garages and workshops for long-lasting performance.

·【6-Point Socket with Concave Arc Design】Our precision-machined 6-point socket features a Concave Arc Design that delivers a tight, secure fit with hex-shaped fastener heads. The rounded arc design on each of the six points allows for easy socket engagement, while force applied evenly across the fastener’s flat surfaces (instead of the corners) effectively prevents fastener rounding and slipping, ensuring maximum torque transfer and reliable, frustration-free fastening every time.

·【High Visibility and Wear-Resistant Markings】Unlike ordinary laser-etched markings that fade and blur with long-term use, each socket of ours features stamped indentations filled with eco-friendly paint for size markings, paired with color-coded rings on the socket heads. This upgraded dual design ensures superb high-visibility, allowing you to quickly locate the right socket even in tight spaces, and the size marking is exceptionally wear-resistant—it won’t fade, smudge or wear off, keeping the size markings crystal clear for years of heavy-duty use!

·【Universal Compatibility & Reliable Quality Guarantee】This 10PCS metric socket set is compatible with all 3/8" drive tools on the market, including ratchet wrenches, extension bars, and various screwdrivers. To extend the product's service life, we recommend avoiding use with electric wrenches as much as possible. It’s ideal for families, construction workers, garage workshops, car repair workers, and DIY hobbyists—and also a perfect gift!
