Applications & Industries
The sectors that buy Inch Fully Threaded Rod to ASTM A193 Grade B7; ASME B18.31.3 and ASME B1.1, and the duty each one buys them for. Stocked from 1/4-20 to 1-1/4-7 (screw size).
Industries that specify Inch Fully Threaded Rod
Refinery maintenanceBolting packages exposed to heat, pressure and hydrocarbon service.
Power generationLarge flanged joints and equipment supports using inch specifications.
Pressure vesselsHigh-strength threaded rod and studs in flanged pressure equipment.
Plant & machine installationAnchoring and levelling machines onto bases and frames.
Steel fabricationHanger rods, tie rods and made-to-length threaded assemblies.
Typical applications
assembling flanged joints where a full-length thread is required
selecting ASTM A193 Grade B7 strength and a compatible finish
cutting standard 3, 6 or 12 ft stock to the required stud length
providing a high-strength inch threaded member for nuts at both ends
made-to-length assemblies cut and threaded on site
clamping a joint from both ends where a headed bolt will not fit
Service conditions to specify against
Marine and coastal
Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
High load
Supplied in ISO 898-1 property classes, so the joint can be designed to a stated proof load and tightened to a calculated torque rather than by feel.
Exterior structural
Hot-dip galvanised options for external steelwork; allow for the thicker coating in the mating thread.
Where to use something else
Do not mix coatings and nut materials without checking thread compatibility and service temperature.
Not for a joint that must be tightened from one side only — there is no head to hold.
Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

What Are Inch Fully Threaded Rod, ASTM A193 B7?
Inch Fully Threaded Rod, ASTM A193 B7 are bolts defined by ASTM A193 Grade B7; ASME B18.31.3 and ASME B1.1. They are selected by screw size and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.
Materials & Finishes
Common materials include carbon steel (typically zinc plated or hot-dip galvanized), alloy steel in property classes 8.8, 10.9 and 12.9, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, property class and surface finish appropriate to your load and environment.
Pricing
Inch Fully Threaded Rod, ASTM A193 B7 are supplied to order. Pricing starts from approximately US$6.00 per piece for standard sizes in carbon steel; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.
Inside the plant
Manufactured in our own plant
This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
01
Cold heading
Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.
Head dimensions and under-head radius checked at set-up and per shift.
02
Thread rolling
Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.
Go / no-go ring gauges to ISO 965 tolerance class 6g.
03
Heat treatment
Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.
Core hardness and tensile tested per lot to ISO 898-1.
04
Surface treatment
Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.
Coating thickness and neutral salt spray hours to ISO 9227.
