ASTM A563M Heavy Hex Nuts
- Category: Hexagon Nut
- Material: Carbon & Alloy Steel
- Range: 1/2” to 2” and M12 to M64.
- Surface Finish: Black/HDG
- Standard Specification: ASTM A563/A563M CL 10S
Description
ASTM A563M Heavy hex Nut specification covers chemical and mechanical requirements for eight property classes of hex and hex-flange carbon and alloy steel.
These nuts for general structural and mechanical uses on bolts, studs, and other externally threaded parts.
Astm A563M Materials shall be tested and the individual grades shall conform to specified values of material such as hardness and proof load, chemical, and mechanical requirements. Classes 8S, 8S3 and 10S, 10S3 nuts have atmospheric corrosion resistance and weathering characteristics comparable to those of the steels. The atmospheric corrosion resistance of these steels is substantially better than that of carbon steel with or without copper addition. When properly exposed to the atmosphere, these steels can be used bare (un-coated) for many applications.
