InterVac F-18 Intake Screw – #8 x 1/2″ Phillips Head Screw

Main Product Description

The InterVac F-18 Intake Screw is a #8 x 1/2″ Phillips head screw that secures the intake on InterVac Pro central vacuum units. Many people don’t realize how important the right screw is for a tight seal, so this fastener keeps the intake firmly attached and prevents air leaks that reduce suction power.

What is the F-18 Intake Screw and Why Do You Need One?

This silver Phillips head screw holds the intake component in place on InterVac Pro models. When the original screw gets lost, strips, or becomes loose, you replace it with the F-18. Therefore, you restore a secure, airtight connection that maintains strong vacuum performance. So your central vacuum system works efficiently without leaks or weak spots.

How the F-18 Intake Screw Works

You insert the F-18 screw into the designated hole on the intake and tighten it with a Phillips screwdriver. The #8 x 1/2″ size provides the perfect length and grip for the Pro intake. After tightening, the screw creates a firm hold that keeps the intake stable and prevents vibration or loosening over time.

Key Features of the InterVac F-18 Intake Screw

This screw features a Phillips head for easy driving and sharp threads for excellent grip. It uses durable metal that resists stripping and rust. Plus, the precise #8 x 1/2″ size makes it ideal for the InterVac Pro intake while remaining versatile for other applications.

Who Uses the F-18 Intake Screw?

Professional installers, DIY homeowners, and RV owners use this screw when assembling or repairing InterVac Pro central vacuum systems. Because it also works well for other general applications that require this exact size, many people keep spares in their toolbox. After you install the F-18, you achieve a clean, secure connection every time.

Easy to Use and Versatile

You can use the F-18 as a direct replacement on the InterVac Pro intake or for other projects needing a #8 x 1/2″ Phillips head screw. Whether you perform maintenance, make repairs, or build a new setup, this screw delivers reliable fastening. InterVac includes it in many assemblies, so having extras prevents delays during installation.
