ASTM A194 is a standard specification issued by ASTM International that covers carbon steel, alloy steel and stainless steel nuts for high-pressure or high-temperature service, typically used with bolts, studs, or other fasteners manufactured to ASTM A193

Description of Material

ASTM A194 Grade 7M Nuts are carbon steel high tensile nuts used predominantly in the oil, gas and petrochemical industries, used in conjunction with ASTM A320 L7M Studs or headed fasteners.
100% hardness checked, achieving a Brinell hardness of 159 to 235, these nuts are tempered or stress relieved after machining, making them suitable for use in an environment which ASTM A194 Grade 7 Nuts are not.
LoneStar hold various options of ASTM A194 7M nuts offering a standard product, or with the supplementary requirements of ASTM A194 or bespoke manufactured to the additional requirements of API 20E BSL 1, 2 or 3.
