Stainless steel eye bolts deliver exceptional durability in corrosive environments where standard carbon steel would deteriorate. Manufactured from premium 304 and 316 stainless steel, these fasteners provide reliable anchoring and lifting solutions for marine, coastal, chemical, and outdoor applications.
Marine & Saltwater Environments 316 stainless steel contains molybdenum, which significantly enhances resistance to chloride attack and saltwater corrosion. Ideal for boat rigging, dock installations, and offshore applications where salt exposure is constant.
Chemical & Industrial Processing Stainless steel withstands exposure to acids, alkalies, and washdown cycles common in food processing, chemical plants, and pharmaceutical facilities environments where carbon steel would rust and compromise product integrity.Long-Term Outdoor Exposure Unlike galvanized steel that requires periodic maintenance, stainless steel eye bolts maintain appearance and structural integrity throughout extended outdoor service without recoating.
Aesthetic & Regulatory Compliance Stainless steel maintains a clean appearance without oxidation or discoloration. Many food-grade and sanitary applications require stainless fasteners for compliance with NSF/ANSI standards.
Type 304 (18-8 Stainless) The standard choice for general marine and outdoor applications. Provides excellent corrosion resistance against most atmospheric conditions and mild chemical exposure. Suitable for coastal environments with moderate saltwater exposure.
Type 316 (Marine Grade) Premium option containing molybdenum for superior chloride resistance. Recommended for heavy salt spray environments, direct saltwater immersion, and aggressive chemical exposures. The preferred material for long-term marine installations and critical applications.
Always use shackles rather than directly hooking into the eye to prevent deformation. Pre-drill holes and use washers to distribute load evenly. Verify thread engagement is adequate minimum 1.5 times the bolt diameter. For applications with continuous vibration or shock loads, use positive thread-locking methods.
Install stainless bolts with stainless nuts and washers to prevent galvanic corrosion when different metals contact. Regular visual inspections will identify any surface oxidation, though stainless steel maintains integrity even with light surface discoloration.
While stainless steel is corrosion-resistant, periodic rinsing with fresh water removes salt deposits and extends service life. Inspect regularly for wear, discoloration, or damage. The non-magnetic property of austenitic stainless steel (304/316) helps distinguish genuine stainless from inferior substitutes.
G-Fast supplies marine-grade stainless steel eye bolts manufactured to ASME B18.15 and DIN 580 standards. Our inventory includes both 304 and 316 grades in shoulder and regular configurations, backed by expert technical support and competitive pricing for industrial and marine applications.
