العربية A2-70 stainless steel hex bolts factory
XZ Fastener manufactures A2-70 stainless steel hex bolts for buyers who need corrosion-resistant metric fastening with clear mechanical property requirements and practical factory packing. Supply can cover DIN 933 full thread hex bolts, ISO 4017 full thread hex bolts, DIN 931 partial thread bolts, and drawing-based stainless hex bolts. A2-70 is commonly selected for 304 stainless steel bolt assemblies where general corrosion resistance, clean appearance, and reliable tensile performance are required. Buyers can combine stainless hex bolts with related fastener products for machinery, enclosures, brackets, maintenance stock, distributor programs, and project-based purchasing.
Quick Specs
What Buyers Should Know Before Sourcing A2-70 Stainless Steel Hex Bolts
A2-70 stainless steel hex bolts are normally ordered when buyers need 304 stainless steel corrosion resistance with a defined mechanical property class. Before quotation, confirm whether the bolt is full thread or partial thread, then provide diameter, pitch, length, wrench size standard, surface condition, nut and washer pairing, and packing method. If your project requires special length, non-standard thread, special head marking, or assembled hardware, XZ Fastener can review custom fasteners according to drawings or samples.
Stainless steel purchasing lists often include both stainless and carbon steel fasteners. To keep sourcing organized, buyers may quote A2-70 stainless hex bolts together with DIN 933 full thread hex bolts, Grade 8.8 carbon steel hex bolts, metric hex head bolts, zinc plated DIN 933 bolts, black oxide DIN 933 bolts, and hot dip galvanized DIN 933 bolts. For carbon steel alternatives, carbon steel fasteners can be reviewed separately according to strength and finish needs.

Material and Grade Explanation
A2-70 usually refers to 304 stainless steel fasteners with a 700 MPa tensile strength class under common stainless fastener purchasing descriptions. It offers general corrosion resistance, clean appearance, and reliable mechanical performance for many indoor and moderate outdoor assemblies. It is not a direct replacement for high-strength alloy steel bolts, so buyers should confirm whether corrosion resistance or higher tensile strength is the main requirement. For dimensional comparisons, the DIN and ISO fastener standards guide can help clarify common bolt standards.
Surface Finish Selection Guide
Plain and Passivated Stainless
Plain A2-70 stainless steel hex bolts are suitable for many industrial assemblies. Passivation can be supplied upon request to improve surface cleanliness after forming, threading, or handling. Buyers should state if passivation, oil-free packing, or special cleaning is required.
Polished, Waxed, or Mixed Finish Orders
Polished or waxed stainless bolts may be used where appearance or installation smoothness matters. If the same project includes plated carbon steel bolts, XZ Fastener can review related coated fasteners together with stainless bolts for a combined purchasing list.
Manufacturing and Quality Control
Manufacturing control for A2-70 stainless steel hex bolts focuses on stainless wire or bar material, forming, thread rolling or threading, head dimensions, thread fit, surface condition, marking requirement, and packing protection. Thread gauges, calipers, visual inspection, material review, and order-based dimensional checks can be used according to buyer specification. Clear drawings, standards, tolerance notes, and packing requirements help reduce confirmation time for factory supply.
Aplicaciones
- Stainless machinery frames, brackets, covers, guards, and panel assemblies.
- Electrical enclosures, instrumentation hardware, cabinet structures, and clean industrial equipment.
- Food equipment, packaging machinery, light outdoor hardware, and maintenance projects.
