Stainless Steel Hex Bolts

A stainless steel (s/s) hex bolt is a threaded fastener featuring a six-sided hexagonal head designed to be driven by a wrench or socket, manufactured from corrosion-resistant stainless steel.

Key Characteristics & Specifications
• Material Composition: Made from stainless steel alloys containing at least 10.5% chromium, providing robust resistance to rust, moisture, and chemical exposure.
• Common Grades:
• SS 304 (A2 / A2-70): Standard grade for general outdoor and industrial applications.
• SS 316 (A4): Marine grade containing molybdenum for superior resistance to saltwater and harsh chemicals.
• Thread Design: Available as fully threaded (e.g., DIN 933) or partially threaded with a plain shank portion (e.g., DIN 931).
• Sizing: Ranging from small metric sizes (M2 or M3) up to heavy-duty industrial sizes (M100 / fractional inches).

Common Applications
• Construction and structural engineering
• Marine and coastal environments (specifically SS 316)
• Chemical processing plants and plumbing fittings
• Automotive and general mechanical assemblies
