Stripped thread blues and time sert

[platypusREX]

Has anyone ever used the Time Sert thread inserts? One of the holes for my bumperette is kaput. I am looking at this kit. Ant other suggestions.
Thanks

Don't think that will work on a captive nut. You can either drill it use a longer bolt and nut or even remove the captive nut and weld a new one in place. Time serts are usually used on blind holes which have much more thread engagement.

Very similar to helicoil kits.

Retap the captive nut and use a longer bolt so that you can add a nut behind the captive to tighten against. Retapping may provide enough threads as it is, you'll have to try and see.

roma's probably right about there not being enough depth to the nut for time-sert inserts. Plus, they're meant to repair holes, not nuts.

The captive nut is in pieces. The PO must of had a bolt break and drilled it crooked. I am going to ACE Hardware and buying a 12" long x 3/4 cold chisel and going to pop the remnants off. and put a stainless nut.

I am going to have to do the same with my bumperette.

Not to hi-Jack your thread but is there some sort of captive nut insert for the back doors to the body? The PO only had to 2 bolts holding the door to the body.

I wouldn't use the Time Sert but I think that Permacoil Thread Repair kit is just like a Heli-Coil knockoff (different brand name) and I've always liked Heli-Coil stuff.

But if the nut is already toast I guess you don't have many options. Heli-Coil inserts have long been used as a way to get stronger threads into softer material (aluminum, etc.) and I would bet a "good" captive nut with a H-C insert might be stronger than the original nut.

I would offer a caution about using a stainless steel nut with lock washer. First, if your bolt doesn't thread in easily, it could gall up on you before it's tight and you will never get it back apart.

If it does go together it can work loose on you. I would use a Grade 8 nut, and washers. Otherwise, if you use stainless I would suggest a Nyloc nut. They hold up to vibration loosening a lot better...
