Why this one
Connects 3/8 inch drive to 10 mm hex
This adaptor features a 3/8 inch female square drive on one end and a 10 mm female hex opening on the other, letting you drive larger hex-head fasteners with a standard 3/8 inch ratchet.
CrV steel to DIN 1173
Manufactured from chrome vanadium steel and built to the DIN 1173 standard, this adaptor is engineered to withstand repeated torque cycles without distortion.
Compact 28 mm length
At 28 mm (approximately 1.1 inches) long, this adaptor keeps overall tool height to a minimum.
Chrome finish for corrosion resistance
The bright chrome finish protects the outer surfaces of the adaptor from rust and oxidation, extending its working life in humid shops, outdoor job sites, and marine environments.
Individual replacement or addition
This adaptor is sold as a single piece, so you can fill a specific gap in your tool collection without buying an entire set.
Read the full description
The Teng Tools M380061-C is a 3/8 inch square drive to 10 mm hex adaptor that lets you drive 10 mm hex-head fasteners using a standard ratchet handle. It is manufactured from CrV steel, built to DIN 1173, and protected with a chrome finish for long service life.
The overall length is 28 mm (approximately 1.1 inches), keeping the tool compact for work in tight engine bays, under-dash areas, and other confined spaces. The female square drive accepts any standard 3/8 inch ratchet, while the female hex opening grips 10 mm bits securely to prevent wobble during high-torque driving.
A 10 mm hex is a common fastener interface on European and Japanese vehicles, heavy equipment, and industrial machinery. Having a dedicated adaptor in your 3/8 inch socket tray means you can reach these fasteners without switching tool systems or hunting for a standalone hex key.
Sold individually, this adaptor is ideal as a replacement for a lost or worn piece, or as a targeted addition to a socket set that does not already include hex-bit capability. The CrV steel construction and DIN 1173 compliance ensure it holds up to the demands of professional daily use.
