Frequently Asked Questions
What size fasteners should I order for my marine chairs?
Measure the hole diameter in the chair base or seat frame. Our M8 (8mm) fasteners are standard for lightweight chairs, while M10 and M12 sizes are recommended for heavier commercial seating. If you are replacing existing bolts, match the length to the combined thickness of the seat base and mounting plate.
Are these fasteners suitable for saltwater use?
Yes, all components are made from 316 stainless steel, also known as marine-grade, which offers excellent resistance to pitting and corrosion in chloride-rich environments. This makes them ideal for both interior and exterior marine applications.
Do the self-locking nuts prevent loosening from vibration?
Absolutely. The self-locking design uses a nylon insert that grips the bolt threads, preventing nuts from backing off due to vessel vibration, which is common in engines and rough sea conditions. For additional security, we recommend applying a thread-locking compound.
Can I order different lengths or custom thread pitches?
Yes, we offer customization for quantity orders. You can request non-standard lengths, fine thread pitches, or special packaging. Contact our sales team with your requirements and we will provide a quote.
