304 Stainless Steel DIN439 A2-70 Hexagon Thin Nuts Drawing Sheet

Description

The A2 70 Hex Nut manufactured to the DIN 439 standard is a high-performance, low-profile fastening component engineered for applications where space efficiency, corrosion resistance, and mechanical strength are essential. Made from premium 304 stainless steel (A2), this thin hex nut delivers a minimum tensile strength of 700 MPa, ensuring reliable fastening performance in demanding industrial and architectural environments.

Compared with standard hex nuts, the DIN 439 thin hex nut features a reduced height, making it particularly suitable for assemblies with limited clearance or for use as a secondary locking nut. Its precise dimensions, clean surface finish, and consistent thread quality support smooth installation and long-term stability across a wide range of applications.

FAQ:

Q1: What is an A2 70 Hex Nut?
A: An A2 70 Hex Nut is a stainless steel hex nut made from A2 (304) material with a minimum tensile strength of 700 MPa, suitable for corrosion-resistant fastening applications.

Q2: When should I use an A2 70 Hex Nut instead of a standard hex nut?
A: Use the A2 70 Hex Nut when you have limited vertical clearance or when you need a "jam nut" to lock a primary fastener in place. Its thin profile allows it to fit into spaces where a standard-height nut would be too bulky.

Q3: Is this nut compatible with a set screw?
A: Yes. These nuts are frequently used to secure a set screw (such as a slotted set screw or a flat end set screw) in place, acting as a locknut to prevent the screw from loosening under vibration.

Q4: Can these nuts be used in the food processing industry?
A: Absolutely. The 304 stainless steel construction provides the necessary corrosion resistance to withstand the moisture and cleaning chemicals common in food-grade environments.
