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.

Good value for a socket for my motorcycle axle.
Works great and saved me money. I'll only use it a few times a year so I don't need the best, just good enough to safely loosen my motorcycle rear axle. Quality was fine.

Tekton 21mm Deep Socket 1/2
The media could not be loaded. Good size 21mm 1/2 good for my Breaker Bar, solid thick material, looks durable but has a bit of a play. I hope it last for a long time with no more stripping lug nuts. Good price for a Tekton tool.

Good and heavy
