Why Choose A563 Structural Heavy Hex Nuts?
Our A563 structural heavy hex nuts at AlbanyCountyFasteners.com, also known as A563 heavy hex nuts, are heavy-duty hexagonal nuts designed for high-strength fastening in structural applications, meeting ASTM A563 specifications. Made from medium carbon or alloy steel (Grades A, C, DH, or 2H), these nuts are available in plain or hot dipped galvanized finishes for corrosion resistance. Thicker and heavier than standard hex nuts, they provide superior strength and thread engagement, ideal for use with A325 structural bolts. Available in imperial sizes like 1/2"-13, 5/8"-11, 3/4"-10 to 1-1/2"-8, they comply with ASTM A563, ASME B18.2.2, IFI tolerances, REACH, and RoHS standards, making them perfect for bridges, buildings, and infrastructure projects requiring robust, reliable fastening.

Frequently Asked Questions (FAQ)
A563 structural heavy hex nuts are heavy-duty hexagonal nuts made from medium carbon or alloy steel, meeting ASTM A563 specifications for high-strength fastening in structural applications.
How do A563 structural heavy hex nuts differ from standard hex nuts?A563 structural heavy hex nuts are thicker, wider, and made from higher-grade steel (Grades A, C, DH, or 2H) for superior strength in structural applications, unlike standard hex nuts for general use.
Are A563 structural heavy hex nuts suitable for marine environments?Hot dipped galvanized A563 nuts offer corrosion resistance for sheltered environments, but for marine settings, 316 stainless steel or silicon bronze nuts are recommended.
How do I install A563 structural heavy hex nuts?Thread the nut onto the A325 structural bolt and tighten with a wrench or torque tool to the specified tension, ensuring proper alignment to avoid cross-threading.
How do I choose the right size A563 structural heavy hex nut?Select based on the structural bolt’s thread size, such as 1/2"-13, 3/4"-10, or 1"-8. Ensure the nut’s thread pitch and grade match the bolt for secure fastening.
