6.3x50mm Tek Roofing Screws – Self Drilling with EPDM Washer (Zinc)

6.3x50mm Self Drilling Tek Screws are designed for fixing metal sheets and roofing panels where maximum strength and deep, secure fixing are required.

The larger 6.3mm diameter provides superior holding power, while the 50mm length allows deep penetration into timber, thick materials, or multi-layer roofing systems, ensuring a strong and reliable connection.

The sharp self drilling tip eliminates the need for pre-drilling, while the hex head allows fast and secure installation using a socket driver.

Each screw is fitted with a bonded EPDM washer to create a watertight seal and help prevent leaks in roofing and cladding applications.

• Self drilling point – no pilot hole required
• Bright zinc plated steel construction
• Bonded EPDM washer for a watertight seal
• Hex head drive for secure installation
• Suitable for metal to metal and metal to timber fixing
