21 mm 150 ft-lb Torque Socket

The Lock Technology 1500BB is a 21 mm torque socket rated to 150 ft-lb. It is designed for technicians who need a precise tightening tool for specific wheel fasteners. The transparent colour allows visual confirmation of engagement during use. This new item suits professional automotive workshops and serious home mechanics.

Behaviour under sustained load

The socket maintains its calibrated 150 ft-lb limit across repeated tightening cycles without drifting. Its construction resists deformation when used continuously on fleet maintenance jobs. The transparent body lets the operator spot any stress marks immediately. Consistent torque delivery reduces the risk of over-torquing lug nuts during high-volume service.

Practical limits of the drive interface

The 21 mm hex size fits only matching fasteners, so it cannot cover other common lug sizes. The 150 ft-lb ceiling means it is unsuitable for applications requiring higher torque values. Users must verify the vehicle specification before selecting this tool. No adapter or extension is included to alter the drive geometry.

Questions about this item

How much force does the 21 mm socket transmit before it stops turning?

The socket is rated to release at 150 ft.-lb., so it will not apply more torque than that value.

What drive tool is needed to operate this 21 mm torque socket?

A standard 1/2 inch drive ratchet or breaker bar fits the socket's square drive.

Will the 21 mm size fit the lug nuts on my older vehicle?

The socket matches 21 mm hex fasteners, which are common on many wheels; verify your nut size before use.
