Manufacturer of Fully heat-treated SA 194 7m Hex, Lock and Square Nut for heavy duty

ASTM A194 7M specification is for inner threaded fasteners and for high tensile nuts which is made from heat treated chromium molybdenum alloy steel. A194 7M can be produced by the method of hot forging, cold forging and machining followed by heat treatment. It is useful for high temperature and pressure. For example oil and gas, energy, construction and the automotive industries due to its high-temperature and tensile strength and corrosion resistance. ASTM A194 Grade 7m Nuts is a fastener with an internal thread. It is utilized in conjunction along with a mating bolt of the similar size. It comes in various types such as flange nut, coupling nut, slotted nut, wheel nut, T-nut, barrel nut, etc. It can be usually reveal to thermal fatigue due to difference in temperature.

ASTM A194 7M Hex Nuts is a six‑sided nut. It is used with bolts, screws, anchor shackles, and other externally threaded elements. In conjunction with these other fasteners, it is used to connect both wood and metal elements to prevent movement and tension. It can be used in the temperatures up to 1150°C. Its durability can be achieved by the addition of several important alloying elements to ensure superior performance across a broad range for high temperature applications.
