03Technical description

The ASTM A563 Grade DH Galvanized Nut is an industrial nut for steel structures, towers, anchors and installations where the drawing requires ASTM A563 DH. It is made from galvanized carbon steel and works with UNC thread; where applicable, the reference is related to ASTM A563 grade DH. Its main difference is grade DH for structural assemblies specified under ASTM, with galvanized finish for exposure. To buy without errors, the critical data is not only the diameter: the pitch, thread series and grade or material of the bolt, stud or threaded rod must also match. TECTUL offers it per unit and organizes selection by actual catalog sizes for maintenance, replacement and production purchases.

Installation recommendations

  • Use only with bolts and washers compatible with the project specification.
  • Do not substitute grade DH with a commercial nut without technical approval.
  • Follow the tightening procedure indicated for the type of structural joint.
  • On galvanized parts, verify that the thread engages freely before final installation.

04Frequently asked questions

What is the price of the astm a563 grade dh galvanized nut?

The price depends on size, finish and quantity. TECTUL quotes this reference per unit and can validate availability before dispatch.

How is it different from the black ASTM A563 grade DH nut?

The HDG version is galvanized for exposure; the black version is used when the design does not require galvanized coating.

How is the astm a563 grade dh galvanized nut installed?

Clean the thread, confirm diameter and pitch, start threading by hand and tighten with the proper tool according to the torque defined for the assembly.

How do I choose the correct size?

Take the nominal diameter and pitch of the male thread. In inch threads, distinguish UNC from UNF; in metric, confirm the pitch indicated in millimeters.

Is it suitable for outdoor use?

It depends on the material and coating. Stainless steel and hot-dip galvanized finishes better resist exposure; zinc plated, black or black oxide finishes are recommended for protected environments.

Is it sold per unit or by package?

The lot is configured per unit. For maintenance or production consumption, TECTUL can quote quantities by size.
