Description
Product Overview
The #10 x 3.0 in. Hex Head SMS Zinc Fastener is a color-matched sheet metal screw designed for aluminum-to-aluminum fastening applications. It is commonly used in screen enclosure systems for securing perimeter 1×2 extrusions to framing members, providing a strong and reliable connection.
Applications & Compatibility
This fastener is primarily used with aluminum screen enclosure extrusions, particularly perimeter 1×2 profiles. While commonly supplied with screen enclosure components, it may also be used in other aluminum fastening applications where a longer SMS fastener is required.
Installation Notes
This is an SMS (sheet metal screw) fastener and is not self-drilling. A pilot hole may be required when fastening into thicker-walled aluminum or dense substrates. Installation is performed using a 1/4 in. hex driver.
Durability & Finish
Manufactured with a zinc coating and available in factory color-matched finishes or mill, this fastener offers corrosion resistance and a clean, uniform appearance when installed with aluminum screen enclosure components.
