Description

Tekton impact drive accessories complement your existing socket system. This set includes 1/4, 3/8, and 1/2 inch drive impact accessories. Attach an extension to your drive tool for reaching past obstructions or into tight, narrow spaces with your socket. Reach around obstructions and access fasteners at an angle with a universal joint. The adapters and reducers can help compensate for lost or broken sockets, fill in gaps for incomplete size ranges, and expand the range of your socket system. The included organization rail comes with twist lock clips and top-mount extension holders. Ridges along the rail prevent the clips and holders from sliding, and a keyhole slot helps it lock into a tray.

Great value, organizer, and complete set for a mechanic.

I have used this set as a professional mechanic for about 8 months now with absolutely no issues. Awesome value for the price. Good low profile swivels, and super nice organizer to keep it all nice in my toolbox.

Great quality and love that they come with their own holder. I've purchased multiple sets from Tekton, always satisfied with the quality and customer service

High quality affordable extensions
Size: 1/4, 3/8, 1/2 Inch
Awesome set of impact extensions and swivels. Got it to throw in my triangle box in the back of my truck. The racks they store in work great and keep them from scattering all over the place. Way more affordable than snappy

Must buy

Great quality! You can’t go wrong with Tekton and their amazing warranty! Buy once for a lifetime tool even if passed down to the next generation in your family!

good investment

I dismantle cars for a living. These work very good. I separated them into drawers of each drive that I own. I've been using them for a few weeks and they work w/out flaws.
