3/8 Inch Square Drive to 1/4 Inch Hex Bit Adapter

The Teng Tools M380060-C is a hex bit coupler with a 3/8 inch female square drive at one end and a 1/4 inch female hex at the other. Fit it to a 3/8 inch drive ratchet, handle or extension bar and it holds standard 1/4 inch hex bits, so the same drive you use for sockets can also turn screws and other fasteners that take a bit. Buyers also look for it as a 3/8 to hex bit adapter, a 3/8 socket to 1/4 hex bit adapter or a 3/8 hex adapter.

A retaining spring inside the hex holds the bit in place. Teng Tools describes the range as coupler adaptors for holding various bits, which makes it useful for the many 1/4 inch hex bits already in a workshop. Bits are not included.

The coupler is made from chrome vanadium with a satin finish for a better grip when handling the adaptor, and it is designed and manufactured to DIN ISO 1173, according to Teng Tools. It is 28 mm (1.1 in) long and weighs 35 g (1.2 oz). Teng Tools lists it as not impact rated, so it is meant for hand ratchets and handles.

It is supplied with a metal socket clip for use with a socket rail, so it can live on the rail with your 3/8 inch drive sockets and is easy to find when a job needs a bit on a ratchet.

What you get: 1 x hex bit coupler, 3/8 inch square drive to 1/4 inch hex, with metal socket clip. Ratchet, bits and socket rail are not included.

• One end is a 3/8 inch female square drive that fits a 3/8 inch drive ratchet or extension bar. The other end is a 1/4 inch female hex that takes standard 1/4 inch hex bits. It works as a 3/8 drive to 1/4 hex adapter, so a bit can be turned with a ratchet where a screwdriver will not reach or will not give enough grip.
• Teng Tools describes these as coupler adaptors for holding various bits. A retaining spring inside the hex holds the bit in place, so it does not fall out when you work upside down or pull the tool back out of a recess. As a 3/8 bit holder it keeps your 1/4 inch hex bits working on the ratchet you already use. Bits are not included.
• Made from chrome vanadium with a satin finish for a better grip when handling the adaptor, and designed and manufactured to DIN ISO 1173, according to Teng Tools. The satin surface gives your fingers something to hold when you push a bit in or change the coupler between jobs with oily hands.
• Supplied with a metal socket clip for use with a socket rail, so the coupler can sit on the rail next to your 3/8 inch drive sockets. It then has a fixed place in the drawer or on the tool cart, and an empty clip shows straight away that it has not come back from the last job.
• The coupler is 28 mm (1.1 in) long and weighs 35 g (1.2 oz), so it adds little length between the ratchet and the bit. Teng Tools lists it as not impact rated, so use it with hand ratchets, handles and extension bars, not an impact wrench. It is also the hex bit coupler Teng Tools includes in many of its 3/8 inch drive sets, among them TTADP17, TTESK86, TM079, T3834 and TT3819, so it replaces one that has gone missing from a set.
