ASTM A194-7 Heavy Hex Nuts are the most commonly used nuts in the fastener industry.ASTM A194-7 Heavy Hex Nuts are relatively strong and durable fasteners that can withstand some special industrial conditions. ASTM A194-7 Heavy Hex Nuts hardness, thickness and tensile strength enable it to withstand some extreme industrial environments.

Large Hex Flange Nut provide a secure and tight fit, while also preventing the nut from loosening due to vibration. This is especially important in industries where machinery and other heavy equipment are used, as any loosening of fittings can cause dangerous and costly consequences. The flange of Large Hex Flange Nut acts as a washer, providing additional support while preventing the nut from embedding itself into the surface of the material being fastened. This greatly reduces the risk of damage to the structure, as well as providing a more aesthetically pleasing finish.
