In the bolt biz there is everything from soup to nuts. You can get a bolt
drilled for wire in any form you can think of. Anyone selling AN hardware can
provide them, AN is Air Force/ Navy standard drawing number.
The SAE grades apply to tensile strength and grade 8 (if I remember
correctly) is just 160,000 pounds per square inch. You count the dimples or bars
on the head and add 2 to get the SAE number. Check me on that. I am getting
old. No marks are grade 2. A bit on the brittle side, but a good general purpose
bolt. Not aircraft quality. Carrol Smiths fasteners
book is very good for all of the smarts you need on bolts.
Only AN and NAS (National Aerospace Standard) (now owned by SAE) a big
mistake in my book. Should be used in the critical systems of
aircraft. Specialty bolts have long series numbers and must be looked up
for performance specs.

also does, and they even have some stuff in Class 8
hardware. But in
all cases, all I've been able to find are zinc plated
variety. Does
it make a difference?
And while we're on the subject of
bolts....safety-tying. If I quote you
correctly, Lynn, you've said,
"Safety-tie everything." I think it is
excellent advice, and I've
been scheming up ways to accomplish the
feat. Is there any place to
get kits of bolts with drilled heads?
There's a lot of bolts even in
just the oil pan to drill by
hand.
