Mountain Mama

I utilized the socket to torque 1800 ft lbs using a hydraulic wrench, and it worked exceptionally well. As mentioned in previous reviews, I discarded the case as it was deemed to be of poor quality.


Worked exceptionally well for my requirements, and I particularly appreciate the durable metal case that houses the sockets.

Kim Oldfield

Most people would never need them, they are so handy when you do. Wide range of sizes.

Worth it

Excellent bargain with high quality. The case, made of blue metal, experienced some rough handling during shipping.

Sockets were heavy duty

The sockets met our expectations. We utilize them in a heavy industrial shop, and they perform as intended. While the case is lightweight for such heavy sockets, overall, we would purchase this set again.
