If you work around anchors or steelwork, you’ve definitely handled a full threaded rod. In the field, people also call it redi-rod, ATR, or TFL. Same idea: threads from end to end, predictable clamping force, and—when sourced right—boringly reliable. Origin here is China, but the use cases are global.
Three things I keep hearing from site managers: faster delivery, consistent coatings, and documentation that actually checks out. Sustainability is creeping in too—RoHS compliance and fewer re-works thanks to tighter thread tolerance. It seems that buyers want traceable heat numbers without paying boutique prices. Honestly, fair.
| Parameter | Spec / Range | Notes |
|---|---|---|
| Diameters | M6–M36, 1/4"–1-1/2" | Other sizes on request |
| Materials | Carbon steel (Q235B/A36), 40Cr/B7, SS304/316 | Match grade to environment |
| Thread | ISO metric 6g, UNC 2A | DIN 976; ISO 965-1 tolerance |
| Property class | 4.8 / 8.8 / 10.9; ASTM A193 B7/B8 | UTS ≈ 400–1000 MPa (real-world may vary) |
| Coatings | Zinc, HDG, Dacromet, Black oxide | Salt spray up to ≈ 240–720 h per ASTM B117 |
| Lengths | 1 m–3 m; cut-to-size | Ends chamfered; deburred |
Materials incoming with mill certs → cut to length → thread rolling (preferred for fiber continuity) or cut threading (for odd alloys) → heat treatment for B7/10.9 → surface prep (SA 2.5 blast when needed) → coating → 100% visual + GO/NO‑GO gauges → tensile tests (ISO 898‑1) → salt spray (ASTM B117) → packing with heat number traceability. Service life? Around 10–25 years in mild atmospheres; marine or chemical exposure changes the math, obviously.
Structural bracing, MEP supports, equipment skids, pipe racks, precast connections, seismic restraints, cable trays, even signage frames. Many customers say a full threaded rod is the “unseen hero” because it just works—and disappears behind the cladding.
| Vendor | Standards | MOQ | Lead Time | Customization | Typical Price |
|---|---|---|---|---|---|
| HBXZ Fastener (China) | DIN 976, ISO 898-1, ASTM A193 | ≈ 500 pcs | 10–20 days | Diameter, cut length, coating | Value-focused |
| Regional Distributor | House spec + ASTM | Box lots | 2–5 days | Limited | Higher, pays for speed |
| Global Brand Supplier | ASTM/ISO full suite | Project-based | 3–6 weeks | Wide, including exotic alloys | Premium |
- Custom cuts and chamfers: on-site installers asked for M16 full threaded rods at 1.2 m—factory cut saved two man-hours per frame.
- Coating swap: coastal walkway project moved to SS316 full threaded rod after zinc trials rusted at ≈ 6 months. Since then, zero call-backs (18 months in).
- Seismic bracing: data center used HDG M12 8.8 full threaded rod with ICC-ES anchors; tensile tests averaged 860 MPa, exceeding minimums. “No drama install,” the foreman said, which is the best compliment.
Factory audits to ISO 9001:2015; materials per EN 10204 3.1. Typical results: B7 M20 UTS ≈ 1000–1050 MPa; 8.8 M16 yield ≈ 640 MPa; Dacromet neutral salt spray ≈ 480–720 h (ASTM B117). All values are batch-dependent, to be honest—ask for the lot certs.
