This might explain difference in cost between the two. The 2.0 nut is used and the copper is new. Note the copper one has elongated hole.

As the Cap'n mentioned, OEM nuts were steel with a helicoiled thread. It's precisely this helicoil thread that keeps them from bonding to the studs in the first place which is why this nut type is so desirable. VW also used this type of nut on their motors as exhaust nuts from the factory albeit without the shoulder on them.
Unfortunately, I have found no where that this type of helicoil nut is now made. However, the same style of nuts are used to hold the transmissions together on the 914 (without the shoulder). Yes, the same 8x1.25x13 with the helicoil centers are likely holding your transmission together right now. Since the transmissions don't get hot enough to really need this type of protection, I replace the trans nuts with standard nylocs and save these special nuts for exhaust nuts. Just an FYI for those of you wanting a real seize-free exhaust nut. . . (IMG:style_emoticons/default/beerchug.gif) |
