ASTM A194 Gr 7 Heavy Hex Nuts Description: “The ASTM A194 Gr 7 Heavy Hex Nuts are produced with hot forging, cold forging and machining from heat treated bar stock.ASTM A194 Grade 7 Nuts are very common in this grade as they are much suitable for high torque tightening.
ASTM A194 Gr 7 Heavy Hex Nuts
Description: “The ASTM A194 Gr 7 Heavy Hex Nuts are produced with hot forging, cold forging and machining from heat treated bar stock.ASTM A194 Grade 7 Nuts are very common in this grade as they are much suitable for high torque tightening.
Able to maintain their strength in high-pressure and high-temperature environments, these nuts are used with ASTM A193 bolts to fasten pressure tanks, valves, and flanges.
”
Steel:4, 6,8, 10,12
User: “The specification ASTM A194 Grade 7 Nuts are used in applications that demand good performance in either high temperature or high pressure environments.This specification fasteners can also be used in those applications that require high performance in both high temperature and high pressure conditions.”
material: Stainless steel, carbon steel and other metal materials
Advantage”The ASTM A194 Grade 7 material specification consists of nuts and various other internally threaded fasteners with high tensile strength. They are made up of chromium and molybdenum-containing alloy steel, which have undergone heat treatments.
