RE: [alfa] Bolt Source

Another good source for metric hardware (although most items have to ordered
in quantity) is metric and multistandard.

www.metricmcc.com

No affiliation, yada, yada, yada ... just a satisfied customer.

Digestians..

Been looking around for replacement bolts..  finding that 10mm x 1.0mm
pitch stuff is apparently kinda rare.
A generous Digestian may supply me with the rare double ended bolt.

McMasterCarr dosen't have it in 1.0mm pitch! (surprised)  Found a local
industrial hardware store that does,
but they are "phasing out" their 8.8 grade stock for 10.9.  I seem to
remember some aversion to the higher
strength stuff,  due to it being more brittle?

In restoring a 66 GTV for vintage racing, I've had great luck with King
Bolt,
626-339-8400, 4680 N Grand Ave in Covina, CA   About half way between the 10
and the 210 on Grand. Not too bad a run up from Irvine.  I love & use
McMaster, but King sells in "each" rather than box quantities for the little
stuff I never need 100 of.  I would have no problem with replacing an 8.8
pan
bolt (pure tension) with a 10.9.  Carroll Smith, the race car builder's
guru,
discusses the high strength brittleness issue in his books, but he was
primarily contrasting the "super unbrako" very high strength commercial
bolts
with the AN (Army Navy) aircraft bolts (very high quality control, lower
absolute tensile ratings), but with the ductility and fatigue resistance
necessary in highly stressed racing applications.  (All my race car
bolts/nuts
are AN, $$$)  At the stress levels and in the application you're looking at,
not an issue.
The double ended bolt I'm no help on a new source, I might have 35 year old
ones in a coffee can someplace if yours are a total loss
I replace all the nuts & lock washers with flat washers & nyloks.

Anyway,  was wondering if there was a good reason to stay with the 8.8,
besides trusting in the engineering
skills of the designers.

Any special suggestions for nuts and washers?  Was thinking about Nylon
lock nuts instead of plain,  for the
heck of it...
