❓ Frequently Asked Questions (FAQ)
Q: Are these bolts true solid stainless steel or just plated steel?
A: They are true A2 (304) solid stainless steel. They are not magnetic plated steel. This ensures excellent corrosion protection for outdoor and humid environments without worrying about the coating peeling off.
Q: How much torque can the wing nut handle before breaking?
A: The wing nut is designed for superior hand-tightening and light tool assistance. It locks down tightly, but please avoid using heavy-duty power tools on the wings, as excessive force can bend the metal. For standard hand pressure, it's incredibly strong.
Q: Are the flat washers the standard size that sits nicely under the bolt head?
A: Absolutely. The flat washers are perfectly matched metric sizes for M3 through M10 bolts. They are loose parts (not captive), giving you the flexibility to use them on either the bolt side or the wing nut side, depending on your project needs.
Q: Are these suitable for saltwater boat environments?
A: A2 (304) stainless steel offers very good rust resistance for fresh water, rain, and general outdoor use. However, for continuous, direct saltwater submersion (marine grade), A4 (316) stainless is usually recommended. These are perfect for decks, docks, and above-water boat parts.
Q: How do I know what Metric size M3-M10 means in inches?
A: Metric is the global standard for fasteners. As a rough guide: M3 (~4-40/3-48 UNM threads), M4 (~#8), M5 (~#10-24), M6 (~1/4-inch), M8 (~5/16-inch), and M10 (~3/8-inch). Please ensure your application requires a metric-threaded bolt.
