Product Description

A563 Carbon Steel Nuts

 

Specification

 

     

      ASTM A563 is the standard specification for carbon and alloy steel nuts of various grades in sizes from 1/4 inch to 4 inches for general structural and mechanical applications on bolts, studs and other externally threaded components. A563 nuts from Glaser and Associates are available in seven grades, A, B, C, C3, D, DH and DH3, offering different mechanical and chemical properties for specific applications. ASTM A563 also covers the American Association State Highway and Transportation Officials Standard AASHTO M-291.

These nuts are designed, manufactured and tested to comply with the standards set by ASTM A563 for hardness, proof load and chemical and mechanical properties.

NOTES:

  1. In addition to the indicated grade marking, all grades, except A563 grades O, A, and B, must be marked for manufacturer identification.
  2. Nuts are not required to be marked unless specified by the purchaser. When marked, the identification marking shall be the grade letter O, A, or B.
  3. Properties shown are those of nonplated or noncoated coarse thread nuts.
  4. Properties shown are those of coarse thread heavy hex nuts.
  5. Properties shown are those of coarse thread heavy hex nuts. Other nuts styles and fine threads may apply.
  6. The nut manufacturer, at his option, may add other markings to indicate the use of atmospheric corrosion resistant steel.

Product application

 

      The ASTM A563 specification covers the chemical and mechanical requirements for carbon and alloy steel nuts used on bolts, studs, and externally threaded fasteners. The charts below address over tapping allowances for hot-dip galvanized nuts, grade marking requirements, and mechanical requirements. For information on suitable nuts for various grades of bolts, visit the Nut Compatibility Chart.

     QBH company according to the A563 specification, “The requirements for any grade of nut may, at the supplier’s option, and with notice to the purchaser, be fulfilled by furnishing nuts of one of the stronger grades specified herein unless such a substitution is barred in the inquiry and purchase order”. This is important because some nut grades are not readily available in certain sizes and finishes. Additionally, the specification allows for the substitution of ASTM A194 grade 2H nuts in lieu of A563 grade DH nuts due to the lack of availability of grade DH nuts in nominal sizes 3/4″ and larger.

       Hot-dip galvanized nuts must be tapped oversize to allow for the added thickness of the zinc on the threads of the externally threaded fastener. These allowances are addressed in the chart below and a more detailed explanation of this issue can be found in the Frequently Asked Questions section of this site.

Various nut styles exist and to some degree are determined by their grade. These styles include hex, heavy hex, square, jam, coupling, and sleeve.
