What does “M4 – M10” mean, and how do I know which size I need?\u003c\/h3\u003e\n\u003cp\u003eThe “M” followed by a number is the metric thread diameter in millimeters. M4 is 4 mm thick, M10 is 10 mm thick. If you’re replacing an existing bolt, measure the inside diameter of the nut or hole. As a rule of thumb, M4 suits light brackets and electronics, M6–M8 handle mid‑range wood\/metal joints, and M10 works for heavier structural connections.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"psd-faq-item\"\u003e\n\u003ch3\u003e2. Are these wing screws actually made from 316 or 201 stainless steel?\u003c\/h3\u003e\n\u003cp\u003eYes. The listing offers both material grades. 316 stainless contains molybdenum for superior resistance to saltwater and chemicals — ideal for marine, pool, or outdoor use. 201 stainless is a lower‑nickel, more economical option with excellent general corrosion resistance for indoor workshops, furniture, and dry environments.

Can I use a hex key or wrench on these if I need extra tightness?\u003c\/h3\u003e\n\u003cp\u003eAbsolutely. While designed for finger tightening, the head includes a hex socket so you can apply additional torque with a standard hex key (Allen wrench) when your application calls for a more secure, vibration‑resistant joint.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"psd-faq-item\"\u003e\n\u003ch3\u003e4. Will these wing bolts rust if left outside?\u003c\/h3\u003e\n\u003cp\u003eIf you choose the 316 stainless steel option, the bolts offer excellent resistance to rust and pitting, even in coastal or rainy conditions. The 201 stainless version resists rust in typical indoor and covered outdoor settings, but for continuous direct exposure to rain, 316 is recommended. Both far outperform ordinary zinc‑plated steel.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"psd-faq-item\"\u003e\n\u003ch3\u003e5.

The exact piece count and length mix are shown in the product images. Typically, smaller diameters (M4, M5) include shorter lengths, while M8 and M10 come in longer options up to around 50 mm.
