🔒 Why Nyloc nuts? The nylon insert creates friction against the male thread, making these nuts ideal for high-vibration applications like engines, pumps, and outdoor equipment. They can be reused several times while still retaining good locking performance.
❓ Frequently Asked Questions – Button Head Screw Kits with Nyloc Nuts & Washers
What is included in each kit? Do I get the screwdriver bits for free?
✅ Each screw is supplied with one Nyloc nut and one flat washer. Additionally, we include the necessary Allen (hex) screwdriver bits to drive the screws (one bit per size, or a multi-bit tool depending on pack size). No need to buy extra tools – you're ready to assemble right out of the box.
Can I reuse the Nyloc nuts after removing them?
🔄 Yes, Nyloc nuts can be reused several times. The nylon insert deforms slightly to grip the threads, so after 5-10 cycles, the locking torque may reduce. For safety-critical or high-vibration applications, we recommend replacing them with fresh nuts. For general DIY, reuse is perfectly fine.
Are these screws fully threaded? What lengths are available?
📏 Yes, all screws are fully threaded for maximum grip. Lengths are measured from under the head. Common lengths include 10mm, 12mm, 16mm, 20mm, 25mm, 30mm, 40mm, 50mm – you choose the exact length when ordering. Custom lengths available upon request for bulk orders.
What materials are these fasteners suitable for?
⚙️ The A2-70 stainless steel construction provides excellent corrosion resistance, making it ideal for outdoor furniture, marine hardware, automotive trim, industrial machinery, and food processing equipment. The included washer protects softer materials (aluminum, plastic, wood) from surface damage.
What spanner/wrench size do I need for the Nyloc nuts?
🔧 M4 nut uses 7mm spanner, M5 uses 8mm, M6 uses 10mm. Standard metric combination wrenches or sockets work perfectly. The hex head of the button screw requires Allen keys (included).
