Stainless Steel 304 Fasteners

Stainless Steel 304 fasteners are parts like bolts and screws, with or without threads, made from Grade 304 stainless steel. This steel contains about 18% chromium and 8% nickel, which forms a natural protective layer on the surface that helps prevent rust and stains without needing extra coating.

They hold up well in humid, mildly acidic, and general outdoor environments. The grade is non-magnetic in its annealed form and has decent weldability. Tensile strength is around 515 MPa, which covers most structural and assembly needs.

You will find SS 304 Fasteners in food processing equipment, chemical storage, architectural work, plumbing, marine fittings, and general fabrication. They are also common in pharmaceutical and dairy plants, where hygiene and corrosion resistance both matter.

Stainless Steel 304 Fasteners Price

The approximate price range and factors affecting it are explained in detail below.

Approx Price Range

In India, SS 304 fasteners usually cost about INR 80 to INR 600 per kg, depending on their type and size. Smaller, common items like hex bolts and nuts are less expensive, while special fasteners like socket head cap screws or eye bolts are more expensive. The SS 304 Fasteners price list is mentioned below.

Price Per kg

Factors Affecting Price

• Raw material cost: Nickel and chromium prices directly affect SS 304 pricing
• Size and thread specification: Larger diameter or finer threads increase machining cost
• Quantity ordered: Bulk orders generally get a lower per-unit rate
• Surface finish: Polished or passivated finishes add to the cost
• Import vs domestic supply: Imported fasteners, particularly from Taiwan or China, may differ in pricing from Indian-made ones
• Certification requirements: Third-party tested or certified fasteners are priced higher

How To Choose The Right Stainless Steel 304 Fasteners Supplier?

The following factors are important for choosing the right Stainless Steel 304 Fastener supplier.

Selecting The Right Supplier

Start with whether the supplier can actually provide the specific type you need: grade, size, finish, and quantity. A lot of traders list everything, but stock only the common items. Always confirm availability before finalising. If you need odd sizes or custom lengths, ask upfront rather than finding out at delivery time.

Technical Considerations

Check what standards the fasteners are manufactured to. For process piping, you need ASTM A193 B8 or B8M compliance. For general structural use, IS or DIN compliance is fine. Make sure the material test certificate (MTC) is available and matches the lot you are buying. Dimensional tolerances also matter, particularly for precision assemblies.

Evaluating Supplier Credibility

Look at how long they have been supplying similar industries. Ask for past client references in your sector. If they have ISO or other quality certifications, that is a reasonable sign of process control. Third-party inspection readiness is a good indicator for larger or critical orders.

Procurement Strategy

For regular requirements, setting up a rate contract with a shortlisted supplier makes sense. It helps with pricing consistency and lead times. For one-off project needs, compare at least two or three quotes. Do not just compare price: factor in delivery time, certification availability, and packaging quality for transit.
