[ARC5] Military bolts

[Robert Rode]

Floyd, just FYI,...british bolts, altho they used same thread pitch as us,
use 55 degree angle on threads, we use 60 degree angle,..I learned this
with my British Triumph Motorcycle long ago,. bolts wud shake loose on me
often,..this turned out to be a problem I wasnt aware of, when I worked for
International Harvester,.. old timer told me many contracted parts for  war
effort British equipment had BIG problems with this, and were shipped befor
any one knew,..I saw one of those mini tanks in the hanger long time ago
befor I was grounded for blood pressure,..another story,..see ya,
Robert/Chicago..
