Great socket!
Great for newer F150 brake caliper bolts. The sockets bites very good and was able to remove the bolts over the recommended 21 socket.

Seems to be good
The socket looks to be of good quality. It worked on removing the pins on my R1100RT. Should be good for installation @ 110 lb. torque.

Durable and Reliable TEKTON 1/2 Inch Drive Socket
The TEKTON 1/2 inch drive x 29 mm deep 6-point socket is a fantastic addition to my toolset. The build quality is solid, and the socket feels very durable, capable of handling high torque without issue. It fits perfectly on fasteners, ensuring a secure grip and reducing the risk of slipping or rounding. The deep design makes it easy to reach nuts and bolts in tight spaces. I’ve used it on various projects, and it hasn’t let me down once. Overall, it’s a great value for the price, offering excellent performance and reliability.

Nice tool, exactly what was needed!
I purchased this socket because of prior positive experience with Tekton tools (which are typically made in Taiwan) and because of its 6 pt configuration. This socket was required to replace the heating element of our motorhome water heater during a road trip. The 12 pt 1-1/2 in socket purchased previously from the local Auto Zone for a significantly higher price turned out to be a complete piece of junk. The socket kept slipping off the hex nut of the heating element as some torque was being applied. This was because of excessive chamfering and the very loose tolerances of the socket which is typical of the junk made in communist China! On the other hand the Tekton socket provided a perfect fit, remained in place while being used and got the job done in no time.
