Stainless steel hex bolt kit with nut and washer A2-70 A4-70

Made from stainless steel (such as 304, 316), these Hex Bolt Sets offer excellent corrosion resistance, high strength and good toughness. The bolts have an easy-to-remove hexagonal head - a push-in fastener, while the washers help distribute pressure and prevent damage to components. Ideal for outdoor, marine, food-processing and general industrial applications where corrosion resistance and reliable fastening are key, such as building stainless steel structures, assembling kitchenware or securing outdoor machinery.

Product Description

Features:

Corrosion & Rust Resistance: Made from A2 (304) or A4 (316) marine-grade stainless steel, which naturally prevents rusting and staining even when exposed to harsh weather or chemicals.
Rolled Threads: Thread profiles are cold-rolled rather than cut, which drastically increases tensile strength and ensures a smoother, tighter fit.
Diverse Head Designs: Available in multiple drive types including hex head (spanner-friendly), tapered socket cap (ideal for low-clearance areas), and dome heads (sleek, load-distributing finish).
Standardization: Most reputable kits comply with international DIN or ISO metrics, ensuring parts can be easily replaced or paired with standard tools.
Upgraded Aesthetics: Premium kits often feature polished mirror finishes or hard-wearing protective coatings (like Diamond-Like Carbon) for a customized look.

Specifications:

Size: M6, M8, M10, M12, M14, M16, etc.
Grade: A2-70(SUS304), A4-70(SUS316)
Material: Stainless steel
Standard: DIN931, ISO 4017, DIN, GB5783, ANSI, ASTM, EN, JIS, AS

Common Uses & Applications:

Solar PV Mounting Systems: Used extensively to secure solar panel framing, mid/end clamps, tracker mechanisms, and bracket foundations. Grade 304 or 316 stainless steel is preferred to prevent galvanic corrosion when interfacing with aluminum rails.
Telecom Towers & Wind Turbines: Securing structural brackets, enclosures, and grounding hardware exposed to high winds and rain.
Docks and Piers: Assembling timber or composite decking structures, handrails, and underwater or splash-zone brackets.
Storage Tanks: Assembling modular chemical storage tanks and their reinforcing structures.
Conveyor Systems & Machinery: Assembling automated sorting, mixing, and packaging lines.
Curtain Walls & Facades: Securing glass and aluminum exterior building panels.
Canopies & Carports: Assembling the structural steel or aluminum framework for outdoor shelters, walkways, and carports.
Pedestrian Infrastructure: Fastening outdoor handrails, guardrails, and safety barriers.
Piping & Valves: Bolting together pipe flanges, valve bodies, and pump housings in wastewater treatment plants.
Fastening deck hardware, cleats, bimini tops, and inboard engine mounts.
Cleanroom Equipment: Stainless steel does not rust or flake, preventing particulate contamination in sensitive pharmaceutical or semiconductor environments.
