ACME PARTS
 
A 1/2" diameter 10 TPI, 2 start valve stem and mating flange for a valve used in a system for carefully controlled atmosphere. H & R made the tap for the flange and has furnished the precision ground operating screw to a customer on the East Coast for many years.



ACME THREAD SCREWS & NUTS Economical cut Acme Threads are machined on our precision Landis Threading Machines from 3/8" to 4" diameter and up to 20 ft. long. Ground Acme Threads from 3/16" to 4" diameter and up to 36 in. long. Experience and extensive tooling enables us to provide all standard threads, left and right hand, multiple start, as well as many specials.


H & R's work with Acme Threads began just after WW II with a request from the Bereau of Reclamation. A massive irrigation project was underway and they required a specialized valve stem. Custom Acme Thread threading dies were designed by H & R and special taps for the matching handwheels. Over several years, through the completion of the project, thousands were produced.

H & R continues to be responsive to clients' special requirements, solving problems with quality parts.
