Why Choose WSMP?
For the better part of a century, WSMP has strived to be America’s most dependable source for precision screw-machined parts. More than 100,000 pounds of bar stock pass through our 28 Davenport multi-spindle machines each month, with millions of parts shipped out across the globe.
Laser Focused on Your Screw Machined Products
If your part can be turned from 1/32” to 7/8” (round) or 3/4” (hex/square) diameter rod, chances are we’ve machined something like it. Our cam-driven process is most cost-effective if your item has an EAU of 50,000+, though we may well be your best choice for as few as 5,000.
Not sure if multi-spindle screw machining is best for your requirements? Don’t be afraid to ask! We’ve successfully machined countless complex parts in-house that people insisted couldn’t be done on a Davenport.
We specialize in machining your high-precision electronic and switch components, heavy-duty valves and nozzles, bushings, toggles and levers, threaded inserts, fittings and couplings, fasteners, and decorative parts for OEM applications. From medical device components with strict tolerances to intricate pen tips, we’ve seen it all. Take a look at a sampling of our screw machined products.


An Experienced Team You Can Depend On.
Our people are what make us special. WSMP is a melting pot of individuals from all over the world, working together to create parts to be shipped worldwide. Walk onto our production floor and you’ll see individuals in their 20s learning the trade from those in their 70s, with hundreds of years of experience between them.
With a well-rounded team of expert setup machinists and seasoned machine operators, we feel we have the best Davenport crew in the business.
Material Sourced in the USA
Though we’re experts in turned brass parts, we also routinely work with ALU-Bronze, stainless steel, cold-rolled steel, copper alloys, and much more. In all, we machine more than 1.5 million pounds of material annually. Everything is sourced directly from mills right here in the USA, and we pass the resulting savings directly on to you.
