Spring
and
fastener
tooling
‘Stripping a thread’ is a small
matter – unless it isn’t, and the
benefits of a groove precision-
cut to within 0.003" are lost to
the end user.
Similarly, the difference between
‘spring’ and ‘sprung’ is minor
– on the page. It bulks larger in
the failure of a spring-engaged
automobile clutch.
Heavy-handedness is a hazard
of the service life of springs
and fasteners. Their manufacture
requires mastery of surface,
form and machining and grinding
methods. But those who provide
the tooling for these specialities
know something else.
The strength of a spring or
fastener need not be apparent.
But it must be real.
