❓ Frequently Asked Questions – Flanged Hexagon Head Bolts
Do I still need a washer when using these flange bolts?
🔧 No. The integrated flange replaces a standard flat washer. It distributes the load and, on many flanged designs, also provides a locking effect against the mating surface. For soft or delicate materials, you may still use a soft washer, but generally, these bolts are designed to be used without additional washers.
Are these bolts fully threaded or partially threaded?
✅ All bolts in this series are fully threaded from under the head to the tip. This provides maximum grip strength and adaptability for any material thickness. Partial thread available upon request for bulk custom orders.
What wrench size do I need for each bolt?
📐 M5 → 8mm wrench, M6 → 10mm, M8 → 13mm, M10 → 15mm. Use standard metric combination wrenches, sockets, or ratchets. The hex head is standard across DIN6921.
Can I order custom lengths? What lengths are commonly available?
📦 Absolutely! “Package Included: As per Your Choice” means you select the length you need when ordering. Common lengths range from 10mm up to 100mm (e.g., 10, 12, 16, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100mm). Bulk custom lengths are also possible — just let us know your requirement.
