I have seat belt mounts that have stripped threads. I'm wonding if HeliCoil's are strong enough in case of an accident. Logic tells me, yes they would be fine if installed correctly, but my gut is a little more nervous than my head. Can anyone tip the scales one way or the other for me?

my spark plug threads are 14mm - i donno about yours.
master cylinder bores are American sizes - what we call 19mm (for example) is actually 3/4". brake caliper mounting ears are 3" and 3-1/2". 7/16" UNF has always been the standard seat belt anchor hardware specification. go buy a set of racing harness eyebolts from Simpson and observe that they thread right into the factory receptacles. use a 7/16"-20 thread gauge on the factory hardware and observe the match. 20 threads per inch == 1.27mm pitch so it's easy to see how they'd look close. This is a typical example. but you don't have to believe me; do the research. (i have no doubt that *somewhere* in the world someone has buggered a set of seat belt mounts for some other thread size...) |
