Stainless Steel 304 Hex Nut

About Stainless Steel 304 Hex Nut

The Stainless Steel 304 Hex Nut is a universally utilized, high-strength internal thread fastener featuring a classic six-sided geometry. Crafted from grade 304 austenitic stainless steel (also known as 18/8 steel due to its 18% chromium and 8% nickel composition), this nut is designed to mate perfectly with matching bolts, screws, and threaded rods to securely clamp materials together. It provides an excellent balance of tensile strength, outstanding rust resistance, and long-term cost-efficiency.

Key Features & Design

         Six-Sided Hexagonal Profile: The standard 6-sided design ensures effortless tool engagement from multiple angles using open wrenches, box spanners, or ratchet sockets.

         Excellent Rust Defence: The high chromium content forms a self-healing chromium oxide film that prevents surface rust, pitting, and discoloration in everyday moisture.

         Anti-Magnetic & Clean: Non-magnetic in annealed states, making it safe for electronics, and presents a polished, bright appearance ideal for exposed, visible installations.

         Thermal Performance: Retains its mechanical strength and resists oxidation across a broad temperature scale, from sub-zero conditions up to 425C.

Manufacturing & Dimensional Standards

Depending on your project's region and engineering blueprints, these nuts are produced to match distinct metric or imperial parameters:

         Metric Configurations:

o    DIN 934 / ISO 4032: Standard hex nut dimensions (ISO 4032 features minor width adjustments on sizes like M10 and M12).

o    DIN 985 / ISO 10511: Nylon insert lock nut variant to resist vibration loosening.

         Imperial (Inch) Configurations:

o    ASME B18.2.2: Covers standard Finished Hex Nuts and thick Heavy Hex Nuts used in heavy industrial joints.

o    Thread Pitch: Available in standard Unified National Coarse (UNC) or Fine (UNF) thread variants with a Class 2B fit tolerance.

Mechanical Properties

         Material Class: Commonly processed to meet Property Class 70 (metric) or ASTM F594 Group 1 (imperial) specifications.

         Proof Load Stress: Delivers a minimum proof load stress rating of roughly 700 MPa, ensuring it can handle high-torque tightening without stripping the internal threads.

Target Applications & Industries

         Domestic & Commercial Construction: Assembling outdoor handrails, architectural canopy glass frames, and internal ventilation ducting.

         Food & Beverage Processing: Fastening conveyor lines, steel mixing vats, and commercial kitchen rigs due to easy cleaning and sanitary traits.

         Automotive & Machinery Manufacturing: Securing brackets, internal engine housing shields, pump bases, and automated factory equipment.

         Water & Irrigation Frameworks: Joining standard plumbing fittings, valves, water storage tanks, and agricultural fluid distribution lines.
