A4 stainless steel contains molybdenum, which gives it much stronger resistance to saltwater, chlorides, and industrial chemicals compared to A2 (304). These wing nuts are suitable for boats, docks, coastal fencing, and other harsh environments where standard stainless steel would eventually rust.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wn-faq-item\"\u003e\n\u003cp class=\"wn-faq-q\"\u003e🔹 Will these fit standard metric bolts from a hardware store?\u003c\/p\u003e\n\u003cp class=\"wn-faq-a\"\u003eAbsolutely.

Avoid extreme force, as it may bend the wings.
