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.

Very nice socket
I ordered for a project but I ordered wrong size, keeping because I will end up using for something later. Well made for an impact socket.

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.
