Modified Truss Screws

Popular in HVAC applications, modified truss zip screws (also known as self-piercing screws) combine easy installation and consistent threads for impressive reliability. Here at All Points Fasteners, our modified truss head zip screws are available in zinc plated or stainless steel and with the option of painted heads. We’re able to offer great prices on our bulk screw and fastener orders, giving you domestic quality at an imported price.

To better suit your needs and cover a greater range of HVAC applications, we offer a variety of different modified truss head screws for sale that combine features such as:

• Zinc plated for corrosion resistance
• Needlepoint point for fast and easy piercing without a pilot hole
• Twin lead thread for consistent screwing every time
• Modified truss head provides a wider bearing surface

You’re getting quality screws that are not only easy to install in your HVAC ducting, but that will also stay in place and avoid corrosion even in humid environments. That’s the benefit of turning to a trusted screw and fastener supplier like All Points Fasteners.

Painted Heads Available

If your installation has a specific appearance requirement, you can choose from our painted-head modified truss screws. Available in black, white or beige, these screws look great on colored ducts and provide a clean, discrete finish. If needed, we can also have these custom painted to match any paint chip that you send to us. You save time since you don’t need to follow up with painting the screw heads after installation.

You can choose from a range of sizes that cover all possible HVAC installation requirements. We offer multiple lengths of #8 modified truss head wood screws, including popular lengths such as 1/2”, 3/4”, 1”, 2” and 3”.
