M36 Threaded Rod & Stud Bolt Weight Chart
Per-meter and per-piece weights of M36 fully threaded rod (same basis for all-thread, threaded bar and double-end stud bolts) across 100–3000 mm lengths (carbon steel, geometric-volume method), kg/m and lb/ft, with pitch, root diameter and tensile stress area — basis fully disclosed.
M36 threaded rod (carbon steel) weighs about 7.8 kg/m; a 1 m bar runs about 7.8 kg and a 3 m bar about 23.3 kg.

| 7.8 kg/m |
Thread Data
| Coarse pitch | 4 mm |
| External thread minor dia. | 31.09 mm |
| Tensile stress area As | 817 mm² |
Pitch and minor diameter are public ISO metric basic-profile geometry; As is the ISO 898-1 tensile stress area used for tensile capacity calculations, not the physical cross-section.

Material Density Conversion
Values above are carbon steel (7.85 g/cm³); for other materials multiply by the density factor.
| Material | Density (g/cm³) | Factor |
|---|---|---|
| Carbon / Alloy Steel | 7.85 | ×1.000 |
| Stainless 304 | 7.93 | ×1.010 |
| Stainless 316 | 7.98 | ×1.017 |
| Brass | 8.5 | ×1.083 |
Basis of Calculation & Disclosed Assumptions
All values are computed as geometric volume × density (carbon steel 7.85 g/cm³, base metal, coating excluded) — no copyrighted standard tables are reproduced. Fully threaded rolled rod = plain cylinder π/4·d²·L × 0.97 (thread-rolling allowance, identical formula and parameters as the online weight calculator). The plain full-diameter figure is 7.990 kg/m; this chart uses 97% of it.
Boundary: theoretical geometric estimates for quotation, freight and lifting budgets. Actual piece weight varies with thread tolerance and coating (hot-dip galvanizing ≈ +4.5%). Use measured values for trade settlement. Double-end studs are cut-to-length products — at the same diameter and length the piece weight matches threaded rod.

FAQ
How much does M36 threaded rod weigh per meter?
On the carbon-steel basis (fully threaded rolled rod at 97% of plain bar) about 7.8 kg/m; a 1 m bar runs about 7.8 kg and a 3 m bar about 23.3 kg. The plain full-diameter figure is 7.990 kg/m.
How much does a M36×3000 threaded rod weigh?
About 23.3 kg per 3 m bar on the carbon-steel basis; a 2 m bar is about 15.5 kg and a 1 m bar about 7.8 kg — see the full 100–3000 mm table above. For stainless 304/316 multiply by the density factors ×1.010/×1.017.
Are threaded rod and stud bolt weights the same thing?
Yes. A double-end stud bolt is threaded rod (all-thread / threaded bar) cut to a fixed length, so at the same diameter and length the unit weight is identical — the kg/m row and the length table of this chart apply to both. The terms threaded rod, all-thread, threaded bar and stud bolt all denote this fully threaded product family.
What are the pitch, root diameter and tensile stress area of M36 threaded rod?
Coarse pitch 4 mm, external thread minor (root) diameter about 31.09 mm, and tensile stress area As = 817 mm² (ISO 898-1). As drives tensile capacity and preload calculations — pair it with the torque chart.
What basis are these weights calculated on?
Geometric volume × density (carbon steel 7.85 g/cm³, base metal, coating excluded), fully threaded rolled rod at 97% of the plain cylinder — the same formulas and parameters as the online weight calculator; the plain full-diameter figure 7.990 kg/m is shown for reconciliation only. Theoretical estimates — use measured values for trade settlement.
