Product Details

Hot Dip Galvanized B7 Threaded Rod is offered as a Threaded Rods for Outdoor structures, construction and corrosive environments. The current supply reference is ASTM A193 Grade B7, with ASTM A193 B7 alloy steel, Hot dip galvanized, and M10-M100; custom length.

Final dimensions, tolerances, grade or class, coating system, matched components, inspection documents and packing must be confirmed against the purchase order, approved drawing or project specification before production.

Selection & Use Steps

Confirm the joint drawing, service condition and governing standard.
Select grade or class, diameter, thread series, length, end configuration and matched nuts or washers.
Specify finish, coating, lubrication, inspection documents and traceability requirements.
Inspect markings, dimensions, threads and coating condition before assembly.
Install using the project-approved tightening sequence, tools and engineering procedure.

Technical Drawing

All-thread stud drawing showing end-to-end length and effective thread length

Confirm all dimensions against the approved drawing before production. Typical control points include overall length, diameter, thread series and tolerance, threaded length, end condition, head or point geometry where applicable, coating allowance and mating-part fit.

The technical drawing shown on this page, when available, is a selection reference and does not replace the buyer-approved manufacturing drawing.

Application Environment

Suitable application depends on the confirmed material, grade, finish and project design. Review exposure to moisture, chemicals, salt, temperature, vibration and dissimilar metals before selection.

For outdoor or corrosive service, confirm that the selected coating or stainless grade is compatible with the required service life and installation method.

Installation & Handling Precautions

Do not mix grades, heat numbers, thread series or nut classes during storage and installation.
Protect threads and coatings from impact, contamination and uncontrolled repair.
Confirm nut and washer compatibility, coating allowance and free thread engagement before assembly.
Do not apply a generic torque value; tightening depends on lubrication, coating, joint design and the approved engineering procedure.
Replace components with damaged threads, uncertain identification or unacceptable coating condition.
