An M6 carbon steel four-claw nut is a fastener with an M6 internal thread, made from durable carbon steel. Its four sharp prongs bite into soft materials like wood or particle board when tightened, creating a permanent, high-strength connection that resists pull-out and rotation. Ideal for furniture and structural applications in woodworking.

Hexagon drill-tail screws (also known as self-drilling hex head screws) paired with transparent washers are integrated fasteners designed for quick, leak-proof installation on metal, aluminum, or PVC profiles. The drill-tail tip eliminates pre-drilling, while the transparent washer (typically made of EPDM or PC) provides excellent sealing, corrosion resistance, and invisible aesthetics—ideal for outdoor or moisture-prone applications.

Invisible Guardians of Industrial Sealing Systems Designed for industrial flange connections, M10 304 stainless steel flat washers are a reliable choice for high-pressure pipeline systems. Forged from 304 stainless steel with 18% chromium and 8% nickel alloy, they form a dense oxide film, ensuring stability in pH 2-9 environments and resisting industrial steam, coolant, and mild chemical corrosion. Precise Specifications for Secure Sealing Compliant with GB/T 97.1 and DIN 125 standards, these 10mm nominal diameter washers (ID 10.5mm, OD 20mm, thickness 1.6mm) fit M10 bolts perfectly. They evenly distribute bolt preload, prevent seal surface damage, and feature a passivated matte finish to reduce installation friction and enhance airtightness. Versatile Industrial Applications Ideal for PN16 chemical pipelines and high-vibration power plant steam flanges, these washers ensure leak-proof sealing with 0.01mm precision. The 40% high ductility of 304 stainless steel absorbs thermal expansion stress, lasting 3 times longer than carbon steel washers. Packed 100 pieces per vacuum-sealed pack, they're ready for bulk use and rust-free storage. Why Choose 304 Stainless Steel? In harsh industrial environments, 304 stainless steel outperforms rubber and carbon steel. With a -20℃ to 150℃ temperature range, it meets food-grade safety standards, costs 80% of 316 stainless steel, and balances economy with reliability.
