Quote from: Lexi on September 08, 2022, 09:42:09 AMI am almost certain that I have those. Just to be sure what length are they (as measured from under the head to the end of the fastener)? Will have a look. What about washers? Think they were special as well. Like thick donuts. Clay/Lexi
Quote from: Lexi on September 10, 2022, 12:23:38 PMThat is great news. Glad Chip could help. Some bolts are designed for one use only as their threads are not designed to be stretched more than once when torqued. Holding strength is compromised if re-used, at least in theory. The science behind fastener technology is quite detailed with much beyond my current scope of expertise. I bought new exhaust manifold bolts from Chip and they are nice repros. Think I had to shorten a couple of them as they were manufactured to fit a number of Cadillac years, (as Chip warned). Not sure if used for intake manifold whether their length has to be altered. If so, make sure you put a "safety" nut on the head's end. After cutting you can "fix" the last "jagged" threads where the cut was made, by turning out the nut to clean up that area. Think Chip ships from Troy Michigan. Clay/Lexi
