Top Quality Tools From Tekton..
I purchased this because another brand socket set I purchased didn't come with a 16mm. So now my set is complete. I have use this socket and its heavy duty and fits perfectly. Tekton is high quality. I have alot of Tekton tools and none have failed.

Solid Socket for Tough Jobs
I recently picked up the TEKTON 1/2 Inch Drive x 36 mm 6-Point Impact Socket, and it’s been a fantastic addition to my tool collection. I needed a reliable socket for some heavier-duty work, and this one delivers. The build quality is impressive—it feels sturdy and durable, giving me confidence when tackling tough jobs. I used this socket to replace the oil control valve on my 2013 Dodge Grand Caravan, and it worked like a charm. The 6-point design grips the fasteners perfectly, reducing the chances of rounding them off, which is a huge plus. The black oxide finish not only looks good but also helps prevent corrosion, so I know it’ll last for a long time. It fits snugly and transfers torque efficiently, making it easy to break loose stubborn bolts. Overall, I’m very satisfied with my purchase. The TEKTON Impact Socket is a reliable tool that gets the job done. If you need a high-quality impact socket for your garage, I’d recommend giving this one a try.

Solid and Reasonably Priced
I have had this tool for eight months and used it often. It is good quality and I have had no issues. I use it to remove the 32mm nut on my motorcycle rear axel at 120NM torque. Never had an issue and it is still holding strong. I would recommend to a friend.

Fits snugly on Impact
This socket is a 10/10. Snug fit on my impact or ratchet. I must say for the price it is very much worth it.

Great buy
So far, Not bad. Seems to be better than some of the smaller sockets I’ve bought at harbor freight. The square drive hole seems to be better, it hasn’t worn out and caused the socket to fall off the impact wrench yet. That’s important to me because i work at heights.
