Import 316 Heavy Hex Nut — Buy in Bulk from Supplier in China

This 316 Heavy Hex Nut is a stainless steel fastener designed for high-stress applications requiring resistance to corrosion and extreme temperatures. It is manufactured to DIN 934 and ISO standards, with thread sizes ranging from M3 to M64, and is available in a hexagonal configuration. The 316 grade offers superior resistance to chlorides and marine environments, making it a preferred choice for outdoor and chemical exposure conditions.

The nut is produced from AISI 316 stainless steel, a chromium-nickel-molybdenum alloy that maintains strength and ductility even in cryogenic or elevated temperature settings. Typical industry specifications for 316 fasteners include a tensile strength of 500-700 MPa, yield strength of 205-310 MPa, and elongation of 30-40%. The hexagonal design ensures compatibility with standard wrenches and sockets, while the heavy pattern provides additional load-bearing capacity compared to standard nuts.

These nuts are commonly used in construction, oil and gas, marine, and chemical processing industries, where reliability in harsh conditions is critical. Buyers typically source them in bulk quantities, with packaging in plywood cases or wooden boxes to prevent damage during transit. They are often paired with bolts, studs, or threaded rods of the same grade and specification to ensure uniform performance in assembled structures.
