💡 Length & ordering info: Screws are fully threaded. Length is measured from the underside of the head (does not include head height). Choose your preferred length (e.g., 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 30mm, 35mm, 40mm) — sold as per your requirement. Contact us for bulk or custom-length orders.
🔧 Pozidriv vs. Phillips: Pozidriv bits have extra small ribs at 45° to the main cross. Use a genuine Pozidriv driver (marked “PZ”) for the best fit. Phillips drivers will work but may come out more easily. We recommend PZ bits for maximum torque and reduced slipping.
❓ Frequently Asked Questions – Pozi Pan Machine Screws
What driver bit do I need for these Pozidriv screws?
📐 Use a genuine Pozidriv (PZ) bit. For M2-M2.5, PZ0 or PZ1 works; for M3-M4, PZ1 or PZ2 depending on length. Phillips (PH) bits will fit loosely and may slip or damage the recess. We strongly recommend PZ bits for the best torque and minimal cam-out.
Are these screws fully threaded? What lengths are available?
✅ Yes, all sizes are fully threaded per DIN 7985. Lengths are measured from under the head. Common lengths range from 4mm to 40mm (e.g., 4,5,6,8,10,12,16,20,25,30,35,40mm). Custom lengths available for bulk orders – just let us know your requirement.
Are these screws corrosion-resistant for outdoor use?
🌊 Yes – A2-70 stainless steel (304 grade) provides excellent corrosion resistance for outdoor furniture, marine trim, and coastal environments. They will not rust like carbon steel. For continuous saltwater immersion, consider A4 (316) stainless, but A2 is perfect for most exterior applications.
Can I use these screws with nuts or in tapped holes?
🔩 Yes, they use standard metric coarse threads (M2x0.4, M2.5x0.45, M3x0.5, M3.5x0.6, M4x0.7). They fit perfectly with any metric nut, threaded insert, or pre-tapped hole of the same size and pitch.
What is the difference between pan head and countersunk head?
🔘 Pan head has a rounded top with a flat bearing surface – it sits above the surface. Countersunk head sits flush or below. Pan heads are ideal when you don't want to countersink or when a low-profile dome is acceptable. They provide a good bearing surface and are easy to drive.
