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.
