Marine 316 Stainless Steel Barrel Bolt - Mirror Polished Latch (60mm)
Marine-Hardware • Top Pick
Check PriceStandard marine latches fail due to material fatigue and chloride-induced pitting. In high-salinity environments, inferior hardware seizes within 48 hours of exposure, rendering access hatches and cabinetry non-functional. For a marine engineer, a seized bolt isn't just an inconvenience; it is a point of mechanical failure that compromises vessel integrity and safety protocols.
Generic 304 stainless steel or zinc-plated alternatives lack the chemical composition to withstand constant spray. These materials develop crevice corrosion, leading to unsightly brown streaks and eventual structural degradation. Furthermore, loose tolerances in mass-produced latches result in audible rattling during engine operation, indicating poor machining and potential hardware failure under vibration.
The Marine 316 Stainless Steel Barrel Bolt - Mirror Polished Latch (60mm) is the engineered solution for professional-grade repair and replacement. Forged via precision lost wax casting, this 60mm latch utilizes AISI 316 stainless steel, incorporating 2-3% molybdenum to significantly enhance resistance to pitting. The mirror-polished finish is not merely aesthetic; it reduces surface porosity, preventing salt crystals from embedding in the grain.
| Feature | Marine 316 Stainless Steel Barrel Bolt (60mm) | Generic Alternatives (304/Zinc) |
|---|---|---|
| Material | AISI 316 Stainless Steel | 304 SS / Zinc Alloy |
| UV Resistance | High (Corrosion Immune) | Low (Prone to Pitting) |
| Price | Premium/Long-term Value | Low Initial/High Replacement Cost |
To maintain ABYC Standards for vessel hardware, all replacement components must meet specific load and corrosion requirements. This barrel bolt integrates seamlessly with existing setups, much like the 316 Stainless Steel Boat Hinge - Mirror Polished Marine Casting (102mm). For heavier deck requirements, consider the 316 Stainless Steel Low Profile Boat Cleat - Mirror Polished (4-10 Inch) or secure your vessel with the AirowMarine 316 Stainless Steel Plow Anchor - Mirror Polish (5kg-50kg).
Technical Glossary
- Lost Wax Casting
- A precision manufacturing process where a molten metal is poured into a mold created from a wax model, ensuring tight tolerances and a superior surface finish.
- Molybdenum
- A chemical element added to 316 stainless steel to increase corrosion resistance, particularly against silicates and chlorides found in marine environments.
FAQ
- Will this latch rust or pit in saltwater environments?
- No, this latch is forged from AISI 316 Stainless Steel, which contains molybdenum to specifically resist pitting and crevice corrosion in chloride-rich saltwater environments.
- Is the bolt movement smooth or does it rattle?
- Thanks to precision lost wax casting, the tolerances are extremely tight. This ensures a smooth slide action while remaining rattle-free during high-vibration engine operation.
- Does this latch come with mounting hardware?
- Mounting screws are not included, but the latch features pre-drilled countersunk holes designed to fit standard #6 or #8 flat-head stainless steel screws for a flush finish.
