❓ Frequently Asked Questions – Hexagon Head Fully Threaded Screws
Are these screws fully threaded or partially threaded?
✅ These are fully threaded set screws per DIN933. The thread runs from just under the head to the very tip. This provides maximum grip and is ideal for applications where the bolt passes through a nut or threaded hole of varying thickness.
What wrench size do I need for each bolt?
📐 M4 → 7mm, M5 → 8mm, M6 → 10mm, M8 → 13mm, M10 → 17mm, M12 → 19mm. Use standard metric combination wrenches, sockets, or ratchets. The hex head dimensions follow DIN933 standards.
Can I use these screws outdoors? Will they rust?
🌊 Yes – A2-70 stainless steel (304 grade) provides excellent corrosion resistance for outdoor use, including coastal areas and freshwater marine environments. They will not rust like carbon steel. For continuous saltwater immersion, consider A4 (316) stainless, but A2 is perfect for most exterior applications.
What lengths are available? Can I order custom lengths?
📦 “As per Your Choice” – select the exact length you need. Common lengths range from 10mm to 100mm (10,12,16,20,25,30,35,40,45,50,60,70,80,90,100mm). Custom lengths available for bulk orders – just contact us with your requirements.
Are these screws compatible with standard metric nuts?
🔩 Yes, they use standard metric coarse threads (M4x0.7, M5x0.8, etc.), which are the most common. They fit perfectly with any metric nut, threaded insert, or tapped hole of the same size and pitch.
