❓ FAQs – A2 Stainless Steel Pan Head Screws
🔸 Are these screws fully threaded? How is length measured?
Yes – they are fully threaded from just under the head to the tip. Length is measured from the underside of the head (the flat bearing surface) to the tip, not including the pan head. For example, an M5 x 20mm screw has a 20mm threaded shank below the head.
🔸 Will A2 (304) stainless steel rust outdoors?
A2 stainless is highly resistant to moisture, rain, and humidity – perfect for most outdoor use. For direct saltwater immersion or heavy coastal spray, A4 (316) stainless is better, but for furniture, appliances, and general outdoor DIY, 304 lasts for years without rust.
🔸 What Phillips screwdriver size works for M3 through M10?
M3: use PH1. M4: use PH1 or PH2. M5: use PH2. M10: use PH3 or a large PH2. Using the correct size prevents stripping. For M10, a PH3 provides better engagement.
🔸 Can I use these screws with nuts, or are they self‑tapping?
These are standard machine screws – they require a matching metric nut (M3–M10) or a pre‑tapped hole. They are not self‑tapping. For best corrosion resistance, pair them with A2 stainless nuts.
🔸 What lengths are available for each diameter?
We offer lengths from 3mm to 100mm. Typical ranges: M3: 4–30mm; M4: 5–40mm; M5: 6–60mm; M10: 10–100mm. Please select your desired length from the dropdown options. If you need a length not listed, contact us.
🔸 Are these screws suitable for food industry or medical applications?
Yes – 304 stainless steel is widely used in food processing and medical equipment due to its corrosion resistance and ease of cleaning. However, for specific sanitary certifications, please verify with your local requirements.
