Threaded inserts where needed

Needed to do a custom skid plate on my CJ. Used these to place threaded inserts to match the new modified YJ skid plate. Worked like a champ. Drilled the holes, used a clamp to hold them and a quick zap with the mig and done. Read more

Hits all the marks

Why did you pick this product vs others?: Well machined and tight tolerances. Threads are cut well without burrs. Plenty of meat to weld to and prevent distortion. Solid inserts that just work. Great value! Read more

Drill, weld, and done.

Machining is good, and the part has plenty of meat for easy welding. The threading is clean, and works as expected. I particularly like the length of thread you get, instead of just a few to catch. If you are looking for a solid part that saves some fabrication time and the need to tap your own threads these just might be for you. Seams to be no issue attaching with the MIG welder, buddy is going to do a nice TIG weld to see how clean they weld up. Read more
