ASTM A194/A563 Heavy Hex Nut
Yokelink Hex nuts are used to fasten attachments to machine bolts, carriage bolts, insulator pins and other bolts. Galvanized hex nuts are tapped oversize to compensate for the corrosion resistant coating on the bolts.
The ASTM A194 specification covers carbon, alloy, and stainless steel nuts intended for use in high-pressure and/or high-temperature service. Unless otherwise specified, the American National Standard Heavy Hex Series (ANSI B 18.2.2) shall be used. Nuts up to and including 1-inch nominal size shall be UNC Series Class 2B fit. Nuts over 1-inch nominal size shall be either UNC Series Class 2B fit or 8 UN Series Class 2B fit. High strength ASTM A194 grade 2H nuts are common in the marketplace and are often substituted for ASTM A563 grade DH nuts due to the limited availability of
DH nuts in certain diameters and finishes.
