Divine Precision
Made-to-print fasteners, valve and fitting hardware and assemblies, machined for corrosion and pressure service.
As a custom fastener manufacturer working from bar stock and billet, we make the parts catalogs don't list: non-standard shoulder lengths, cross holes through threads, flats, knurls. Our custom made screws are cut to your print.
Cut threads are not rolled threads. For plain standard-head bolts in very high volume, cold-headed catalog parts cost less. If the joint is fatigue-critical or your print calls for rolled threads, tell us when you quote.
Upload a STEP or IGES model with a 2D drawing through Get Instant Quote, or send the files to our engineers. Quotes come back within hours, and an NDA is available. See our stainless valve fittings case.
Custom bolts and studs turned to print for machinery and fluid systems.
Set screws with cup, flat, cone, dog or oval points, plus plain and threaded pins with cross holes or flats.
Turned hardware for corrosion and pressure service in hydraulic, pneumatic and process lines.
Fasteners assembled, tested and packed to your specification.
316L and 303 stainless are turned from certified bar and passivated after machining.
Small screws and pins on Japanese and German Swiss automatic screw machines, including CITIZEN. The Swiss-or-CNC turning choice is made part by part.
Larger bolts, studs and billet parts. Twin-spindle turn/mill machines cut threads, flats and cross holes in one flow.
Zinc, nickel and electroless nickel plating, plus passivation, applied in-house or with trusted partners.
Send a drawing and we reply within one business day.
Ask a QuestionYes. All work is manufactured to customer drawings, the minimum order is 1 piece, and runs go to 100k+. A STEP or IGES model plus a 2D drawing with GD&T gives the fastest and most accurate quote.
Price depends on material, thread, tolerance, plating and quantity, so there is no list price. Ask for several quantities in one RFQ to see how the unit price moves between a small lot and a full run.
For 3D, send STEP, IGES, SolidWorks or ProE files. For 2D, send PDF or DWG. A STEP or IGES model with a 2D drawing carrying GD&T is ideal. An NDA is available before we open any drawing.
Rolling work-hardens the thread and suits high-volume, fatigue-loaded bolts. Cut threads suit small lots, odd features and grades that are hard to form. If your joint is fatigue-critical, flag it on the RFQ and we will advise whether to machine or source rolled.
The minimum is 1 piece. Prototypes can ship in as little as 3 days, and production lots typically take 4–6 weeks. Rush options exist for many jobs and are confirmed on the quote.
Each lot carries a material certificate and an inspection record. The first-article report is approved before the batch starts, and a full FAI or PPAP package can be added when your program calls for one. Work runs under our ISO 9001:2015 quality system, traced from raw material to finished part.
Threads run M1.6–M36 and UNC/UNF, machined rather than rolled. Turning covers 3–65 mm diameter from bar stock and up to 200 mm for billet work. Materials include free-machining and alloy steel, brass, 303, 304, 316L, 17-4PH, titanium and aluminium. We don't supply to a bolt property class; strength comes from the material and heat treatment on your print.
