Clamping Fastener with Pierce Point - CXLW-48 - Austenitic Stainless Steel Fasteners

CXLW-4,8 clamping fastener is made from A4 or A2 austenitic stainless steel and supplied with aluminum AV shaped washers. The head form types are available in the industry standard 8 mm hex head and 10 mm pan head.

Features and benefits:

• Fast and chip-free installation.
• FastTip® self-drilling fastener suitable for fastening of overlaps and flashings.
• Hybrid fastener suitable for fastening onto metal and timber sub construction.
• No scratches on painted metal surfaces thanks to the sharp FastTip®.
• Secured against unwinding given by cut-off thread-end and free-spin zone.
• No torque control required given by free-spin zone.
• Cost saving installation due to pre-drilling of metal sheets no longer necessary.
• High quality ethylene propylene diene monomer (EPDM) sealing washer with special AV-shaped for highest clamping range and long-term weather sealing.
