About A2-70 Hex Nut

The A2-70 Hex Nut is a high-quality, standard metric internal thread fastener engineered for everyday industrial and structural clamping. The alpha-numeric designation "A2-70" explicitly defines its material and mechanical properties under international standards like ISO 3506-1:

"A2" indicates it is made from Grade 304 austenitic stainless steel (18% Chromium, 8% Nickel).

"70" signifies a high minimum tensile strength of 700 MPa, achieved through precise cold-working.

Featuring a traditional six-sided profile, this nut pairs with matching A2-70 bolts or threaded rods to deliver exceptional torque retention and long-term atmospheric rust protection.

Key Features & Design

Optimized Tensile Strength: The cold-hardened "70" property class ensures the internal threads resist stripping and deformation under high tightening torque.

Six-Sided Driving Geometry: Designed with standard flat sides for stable tool engagement using metric spanners, sockets, or open wrenches.

Excellent Atmospheric Protection: The A2 composition forms a self-healing surface layer that prevents rust and staining in moisture, outdoor environments, and fresh water.

Clean Metallic Polish: Provides a bright, aesthetically pleasing finish that eliminates the need for flaky anti-corrosion plating or coatings.

Manufacturing & Dimensional Standards

A2-70 hex nuts are manufactured strictly to global metric dimensional specifications:

ISO 4032: The modern international standard for regular hex nuts (Product Grades A and B).

DIN 934: The classic, widely utilized German industrial standard for standard hex nuts.

DIN 985 / ISO 10511: Nylon insert lock nut variant ("Nyloc") designed to prevent vibration loosening.

Thread Fitting: Machined to standard metric coarse or metric fine thread pitches with a precision 6H internal thread tolerance class.

Mechanical Property Profile

Material Matrix: Austenitic Stainless Steel (Type 304 / 18-8).

Minimum Tensile Strength: 700 MPa (700 N/mm).

Minimum Proof Load Stress: Matches the high tensile rating to guarantee structural safety under heavy preload clamping forces.

Magnetic State: Non-magnetic in the raw annealed state, though it can develop slight magnetism after the cold-threading manufacturing process.

Target Applications & Industries

Automotive & Transport Maintenance: Securing bracket mountings, protective shields, internal panels, and non-critical engine bay fixtures.

Commercial Architecture & Construction: Assembling outdoor balustrades, glass canopy framing, structural signages, and urban street furniture.

Food & Catering Hardware: Used in commercial kitchen assembly, processing conveyors, and refrigeration units due to hygienic, washable surfaces.

Solar & Renewable Energy: Fastening solar PV panel racking clips, mounting structures, and inverter framing panels in outdoor fields.

High-Quality Stainless Steel Construction

Made from S.S. 304 stainless steel, the A2-70 Hex Nut guarantees superior corrosion resistance, making it excellent for use in harsh environments. The meticulously polished and buffed finish not only enhances its appearance but also adds to its durability and longevity.

Versatile Metric Thread Design

This hex nut is engineered with a metric thread type, rendering it compatible with a broad array of bolts and fasteners. The metric threading ensures precise fit and optimal strength for secure fastening in construction, machinery, automotive, and other industrial uses.

FAQ's of A2-70 Hex Nut:

Q: How does the corrosion-resistant property benefit the A2-70 Hex Nut in various environments?

A: The corrosion-resistant nature of the A2-70 Hex Nut, made from stainless steel 304, ensures that it remains durable and reliable even in environments exposed to moisture, chemicals, and fluctuating temperatures. This feature minimizes the risk of rust and degradation, extending the nut's lifespan.

Q: What is the typical usage of the A2-70 Hex Nut with a polished finish?

A: The A2-70 Hex Nut is commonly used in applications demanding both functional strength and a clean appearance, such as architectural structures, machinery assembly, and automotive projects. Its polished finish makes it suitable for visible installations where aesthetics are important.

Q: When should I choose a metric thread type for my fastening needs?

A: A metric thread type, as featured in the A2-70 Hex Nut, should be selected when working with compatible metric bolts or components, especially in regions or industries that standardize metric measurements. Metric threads offer global compatibility and standardized strength.

Q: Where are these stainless steel hex nuts typically exported and supplied?

A: These hex nuts are exported and supplied worldwide, catering to industries such as construction, engineering, and manufacturing. As a trusted exporter, manufacturer, and supplier, we deliver to both domestic and international clients needing reliable fastening solutions.

Q: What is the process behind achieving the buffed and polished finish on these nuts?

A: The buffed and polished finish is achieved through a series of mechanical polishing and buffing steps, which smooth the surface and enhance both the nut's appearance and resistance to surface oxidation. This process ensures the product is free from rough edges and surface imperfections.

Q: How is the hex drive type advantageous during nut installation?

A: The hex drive type allows for efficient torque application using standard wrenches or sockets, making installation straightforward and secure. This design enables even force distribution, reducing the risk of slippage or stripping during tightening.
