Three Ways Threaded Rod Gets Made
Knowing which tier your part belongs to saves money — sometimes with us, sometimes without us:
Mass-rolled all-thread
Mills roll standard diameters and pitches in zinc-plated steel and A2 by the ton. If M10×1,5 × 1 m plated rod does the job, buy it off the shelf — nobody can compete with that price.
Cut-to-length services
Distributors saw tier-1 rod into your lengths and chamfer the ends. Fast and cheap — but still limited to the diameter/pitch/material combinations the mills roll.
Cut thread from bar — this page
The thread is single-point cut on a CNC lathe from the bar you specify. Any pitch, any hand, any material, any length section threaded or plain. This is where the combinations that don't exist get made — one piece at a time if needed.
The Combinations Stock Rod Never Covers
| You need | Stock all-thread | Cut from bar (us) |
|---|---|---|
| Fine pitch — M12×1, M10×0,75, M16×1,5 | rarely rolled | any pitch, gauged 6g |
| Left-hand thread — turnbuckles, spindles | a few sizes, if lucky | any size, both hands on one rod |
| Imperial & obsolete — 1/4-28 UNF, BSW, BSF | regional stock at best | gauged from your sample |
| Materials — titanium, brass, duplex, 42CrMo4 certified | steel and A2 mostly | machined from certified bar, 3.1 cert |
| Part-threaded — thread only where needed | full thread only | threaded and plain sections to drawing |
| Tight straightness & tolerance | commercial grade | turned between centres, checked |
The nut already on the machine decides the pitch of the rod. Threaded rod is stocked in the standard coarse pitch, and in a few common fine pitches in the smaller sizes; above M64 fine-pitch rod is a special order almost everywhere. So before buying a length of rod, measure the nut or the tapped hole it must enter: a steel rule across ten crests, divided by ten — 60 mm means 6, 40 means 4, 30 means 3. If the reading matches the stock rod for that size, buy it by the metre and cut it. If the nut is a fine pitch, a left-hand thread or an inch count, the rod is threaded to it here, cut to length, with the ends chamfered. Measuring the pitch before you order →
Two neighbours of this page: a rod that has to meet a rod of another diameter or pitch is joined with a threaded rod adapter — a reducing coupling nut, both threads gauged; and a rod carrying a 29° power thread rather than a fastening thread is an ACME threaded rod, cut on the lead-screw page.
Stud Types We Machine
Materials & Verification
- Carbon steel C45 and alloy 42CrMo4 (B7-equivalent, quenched & tempered) — with EN 10204 3.1 certificates from series
- Stainless A2-70 / A4-80 — chemical, marine and washdown environments
- Duplex & super duplex — offshore fastening per your spec
- Titanium Grade 5 — weight-critical and high-corrosion applications
- Brass — electrical and instrument rods, non-sparking
Every thread is checked with go/no-go ring gauges in the exact pitch — including the odd ones, where we source or make the gauge alongside the job. Dimensional report on request.
Rod too long to ship as one piece? We machine coupling nuts in the same material and thread so sections join on site — one supplier, one certificate package, threads guaranteed to match.
Rod Weight & Material Cost — Compare Live
Threaded rod is cut from round bar, so material sets the weight and cost per metre directly — 6061 aluminum and titanium cut weight, carbon and alloy steel carry the most load for the least money, and 304 or 316L stainless resists corrosion. Enter the rod diameter and length for a close weight and relative-cost comparison across materials (the weight of the bar it is cut from):
Where two rods have to be joined or one extended, the coupling nuts for threaded rod page gives the engagement per rod and the breaking loads by size, and the nuts are made with the rod.
A rod that ends in an eye — eye-end hanger rods, cast-in anchor eye bolts and long-shank eye bolts supplied with nut and washer — is drawn and quoted on custom eye bolts.
Frequently Asked Questions
Cut-to-length saws stock all-thread shorter — limited to combinations mills mass-produce. We cut the thread itself from bar: any pitch, hand, material or length section. If stock covers your need, use a cut-to-length shop; when the combination doesn't exist, we make it.
Yes — fine pitches are the top reason stock rod fails buyers. Any ISO 261 pitch and beyond, single-point cut and gauged to 6g.
Full-thread, tap-end, double-end (different threads each end), stepped studs and long tie rods — each machined as one piece from bar, never welded halves.
Past 1000 mm in one piece depending on diameter; longer runs join with matching machined coupling nuts.
Yes — EN 10204 3.1 traceable to bar heat, plus dimensional reports. Critical rods run from certified 42CrMo4, A4-80, duplex or titanium bar.
