Allthread (Threaded Rod) Selection — Quick Reference
Allthread = continuously threaded rod (also called studding or threaded rod) used in construction + fitout + engineering + maintenance for hanging + bracing + anchoring + joining. Selection turns on thread system (metric/imperial), grade (mild vs Grade 4.6 vs Grade 8.8), and corrosion finish.
| Allthread Spec | Best For | Common Lengths |
|---|---|---|
| Mild Steel Allthread (Zinc-Plated) | General fitout + suspension + bracing — indoor | 1m / 2m / 3m standard |
| Hot-Dip Galvanised Allthread | Outdoor + light corrosion + bridge/civil | 1m / 2m / 3m |
| 304 Stainless Allthread | General corrosion-resistant + indoor outdoor | 1m / 2m / 3m |
| 316 Stainless Allthread | Marine + chemical + chloride service | 1m / 2m / 3m |
| Grade 8.8 High-Tensile Allthread | Structural + load-bearing applications | 1m / 2m / 3m |
| Metric Sizes | M6 / M8 / M10 / M12 / M16 / M20 / M24 | Standard AU + EU machinery + construction |
| UNC + UNF Imperial Sizes | 1/4" / 5/16" / 3/8" / 1/2" / 5/8" / 3/4" | US-origin + automotive imports |
| Cut-To-Length Service | Custom lengths from bulk rod | Per request |
Critical: Match nut + washer to allthread grade — Grade 8.8 allthread with Grade 4.6 nuts = nut strips at lower torque (downgrades the system). Pair Grade 8.8 with Grade 8 nuts + hardened washers. Cutting: use hacksaw or angle grinder cut-off disc — chamfer cut end before threading nut on (sharp end damages thread). For hanging service: rated load = allthread tensile strength × safety factor (typically ÷5). Companion: fasteners, threaded rod, hex bolts + nuts, threaded rod guide.
All Thread Rod
Allthread (threaded rod or studding) is continuously threaded rod used in construction, fitout, engineering and maintenance for hanging, bracing, anchoring and joining. AIMS Industrial stocks metric and imperial allthread in mild steel, hot-dip galvanised and stainless steel (316 and 304) for structural and corrosion-resistant applications.
Construction and Fitout Applications
Allthread is the standard suspension rod for HVAC duct hangers, cable tray supports, pipe hangers and suspended ceiling grids — run from cast-in anchors or sleeve anchors through the structure above and terminated with nuts and flat washers on each side of the supported component. In formwork, allthread is used as through-bolts to tie opposing ply faces under concrete pour pressure. In fitout, M8 and M10 allthread is used extensively for adjustable shelving supports and furniture fixings.
Material Selection
Mild steel allthread suits internal and covered structural applications. Hot-dip galvanised allthread is used externally and in environments where moisture exposure would corrode bare steel — roof structures, open-air structures and coastal construction. Stainless steel allthread (316 grade) is specified for marine and aggressive chemical environments, food processing plants and pharmaceutical facilities where corrosion resistance is paramount and galvanised coatings are not suitable.
Sizes and Lengths
Standard metric allthread is available from M6 to M30 in 1m and 3m lengths for cutting to requirement on site or in the workshop. Common imperial sizes (3/8" UNC, 1/2" UNC) are also stocked for legacy plant and equipment. For help with allthread specifications, quantities or cut lengths, contact our team.
