Description
This 1/4-Inch-14 x 2-1/2-Inch self-drilling screw from Timberline is designed for fast, reliable fastening where you need a strong, corrosion-resistant connection. Its hex washer head delivers firm bearing surface and easy wrench or socket driving for consistent torque, while the zinc finish gives a bright silver appearance that resists rust in general-use applications. Use these screws when joining metal framing, attaching roofing and siding materials, or securing heavy trim where a larger #14 diameter and 14 TPI provide extra holding power. The self-drilling point eliminates the need for predrilling in many thin-gauge metals, speeding installation on job sites and DIY projects alike. Built for contractors and homeowners who want efficient, dependable performance, these screws make repetitive fastening quicker and more precise without sacrificing strength.
