A4 70 And A4 80 Stainless Steel Hex Nut

What is A4 70 And A4 80 Stainless Steel Hex Nut

A4 70 Stainless Steel Hex Nut:

A highly reliable and versatile fastener, the A4 70 stainless steel hex nut can be utilised in multiple applications. Its A4 grade stainless steel composition makes it withstand rust, as well as applicable in outdoor and aquatic conditions. The “A4” label indicates that it is constructed from austenitic stainless steel, which contains considerable levels of nickel and chromium to resist corrosion.

The hex nut, with its six-sided design, offers a strong and reliable grip when coupled with a matching bolt or threaded rod. The A4 70 classification demonstrates the nut’s capacity category; in this case, “70” implies the least amount of stress that the nut can endure, which is expressed in megapascals (MPa). A higher number represents a tougher nut, able to endure much greater forces.

A4 80 Stainless Steel Hex Nut:

Similar to the A4 70 stainless steel hex nut, the A4 80 variant is also made from austenitic stainless steel, providing excellent corrosion resistance and durability. However, the A4 80 nut has a higher strength class, denoted by the “80” designation, indicating a minimum tensile strength of 800 MPa.

The increased strength of the A4 80 stainless steel hex nut makes it suitable for demanding applications that require a more robust fastening solution. Industries such as aerospace, heavy machinery, and structural engineering often rely on A4 80 nuts for their high-performance requirements.

Both the A4 70 and A4 80 stainless steel hex nuts offer reliable fastening solutions with excellent corrosion resistance properties. Their material composition and strength classifications make them suitable for various industries and applications, ensuring secure and long-lasting connections in challenging environments. Whether used in construction, automotive, or heavy machinery, these nuts provide the reliability and durability required for demanding fastening needs.

At our company, we take great care in packaging both the A4 70 and A4 80 stainless steel hex nuts. Each nut is individually wrapped in protective packaging to prevent any damage or scratches during transit. We ensure that the packaging is sturdy and secure, providing adequate cushioning to maintain the nuts’ integrity. Our goal is to deliver the nuts to our customers in pristine condition, ready for immediate use.
