Torx Bolt Size?

I have a 88 Iroc convertible and I'm trying to figure out what the size of that big torx bolt that holds the seat belt mount to the floor.

Buy the set, you're going to need enough of them that it's cheaper to just buy the complete set.

T-50

I bought a set of Sears Craftsman for my seat belt reciever search.
Less than $20 bucks.

I figured lifetime guarantee (at the time) and figured if I snapped
one I would get a free replacement.

I don't normally buy tools at Autozone but their 3/8 socket Torx bits work really well. Far less slipping/stripping than what I experience with Craftsman.

Re: Torx Bolt Size?

When you're working with torx (especially those seatbelt ones) bolts be sure the inside of the torx head is clean, put the socket on and give it a tap or two with a hammer.

Re: Torx Bolt Size?

And the torque spec is 31 lb-ft, not nearly as tight as you might think. I remember putting a lot of muscle into it when I was young and stupid. Now I actually pay attention to torque specs.
