14g X 50mm T17 Hex Flange with Seal Roofing Screw + Washer SS316 External Hex Drive 500 Pack

This pack of 500, 14 gauge by 50mm roofing screws are designed to provide a reliable, long-lasting hold in roofing applications. Each screw features a Type 17 slash point, meaning you get fast, self-drilling action straight into the material, saving you time and effort on site. The 316 grade stainless steel construction ensures superior corrosion resistance, critical for Australian conditions, especially in coastal areas. They're built to handle the harsh sun, rain, and salt air without compromising their integrity.

The hex flange head provides a large bearing surface, distributing clamping force evenly and preventing over-tightening. This reduces the risk of damage to roofing sheets. Integral to the design is the high-quality seal and washer, creating a watertight barrier against moisture ingress and leaks. These screws are driven with a standard 3/8" hex socket (nutsetter), making them compatible with most impact drivers and nut runners commonly used on building sites. With 10 threads per inch, you can expect a secure, strong hold.
