Stainless steel hex nut is a type of fastener with internal threads that plays a critical connecting role in piping systems. Its main function is to serve as one of the three components of a union, tightly connecting the two ends of the union to form a seal through rotational locking. Its hexagonal shape design provides convenient clamping points for using standard wrenches, ensuring easy and secure tightening.

Our low-pressure threaded pipe fittings series mainly offer two pressure grades: Class 150 and Class 300. This nut belongs to Class 150, which is the most widely used grade and suitable for most general plumbing, HVAC, and industrial utility systems. The Class 300 provides a higher safety factor for slightly higher pressure conditions. These two levels together cover the vast majority of medium and low voltage non critical application scenarios.

According to the American Society for Testing and Materials ASTM A351 standard, CF8 is the casting grade corresponding to 304 stainless steel. Although there are slight differences in the chemical composition between the two in the standard, their mechanical properties and corrosion resistance are considered equivalent under normal operating conditions. Therefore, in industry practice, "304" and "CF8" are often used interchangeably, and our product can meet your performance expectations for this universal grade.

SMLSCO is a stainless steel fitting factory, provide stainless steel fitting OEM. Our Stainless steel hex nuts are widely used fasteners in threaded piping systems. In addition to being the core components of flexible joints, they are also used for fixing various pipeline supports and hangers, bolted connections of equipment flanges, and other requirements
