Why Choose Fastgrip™ Mechanical Galvanized Roofing Screws?
Fastgrip™ mechanical galvanized roofing screws are used when metal roofing or siding components need to be fastened into wood. They are designed for metal-to-wood roofing applications where the screw must pass through a metal panel and hold securely in wood purlins, wood framing, decking, or similar wood substrates.
This category includes Fastgrip™ roofing screws in mechanical galvanized steel with painted and unpainted finish options. These screws are commonly selected for exposed-fastener roofing and siding projects where the installer needs the right combination of point style, thread design, washer seal, coating, color, and length.
Common Uses for Fastgrip™ Roofing Screws
Fastgrip™ roofing screws are commonly used for fastening metal roofing panels, siding panels, trim, flashing, closures, and other sheet metal roofing components into wood substrates.
They are often used on pole barns, garages, sheds, agricultural buildings, residential metal roofing projects, commercial siding, and repair work where metal panels are being secured to wood. Color-matched Fastgrip™ screws are useful when the screw head will remain visible on the finished roof or wall surface.
Fastgrip™ Hi-Lo Thread and Type 17 Point
Fastgrip™ roofing screws include options with Hi-Lo thread and a Type 17 point. The Hi-Lo thread helps the screw engage wood, while the Type 17 point helps start the screw and reduce wood splitting in many metal-to-wood roofing applications.
These features make Fastgrip™ screws a practical choice when fastening metal panels into wood substrates. Choose the screw length, diameter, washer style, and finish based on the panel thickness, wood substrate, exposure level, and finished appearance needed for the job.
Mechanical Galvanized vs Stainless Steel Fastgrip™ Roofing Screws
Mechanical galvanized Fastgrip™ roofing screws are a common choice for metal-to-wood roofing and siding applications where a galvanized coating is suitable for the project environment. They are available in painted and unpainted head options for exposed-fastener installations.
Stainless steel Fastgrip™ roofing screws may be preferred for applications where stainless material is required for corrosion resistance, material compatibility, or job specifications. Choose the material and coating based on the environment, panel type, substrate, and project requirements.
Painted vs Unpainted Fastgrip™ Roofing Screws
Painted Fastgrip™ roofing screws are a good choice when the screw head will remain visible against painted metal roofing panels, siding panels, trim, or flashing. Color-matched options help the fastener blend into the finished installation.
Unpainted Fastgrip™ roofing screws are often used for utility fastening, hidden or less-visible locations, repairs, unpainted panels, or applications where color matching is not required. Choose the finish based on whether the screw head will be visible after installation.
Fastgrip™ vs Fastgrip MINI-DRILLER™ Roofing Screws
Fastgrip™ roofing screws are used for metal-to-wood roofing and siding applications where the fastener secures metal panels into wood. Fastgrip MINI-DRILLER™ roofing screws are related metal-to-wood options used when the screw needs to work through metal before anchoring into wood.
The best option depends on the panel thickness, connection type, substrate, drill point, screw length, washer style, and installation requirements. If the screw is being installed into wood purlins, wood framing, decking, or another wood substrate, choose a metal-to-wood roofing screw style.
Sealing Washers and Exposed Roofing Applications
Many Fastgrip™ roofing screws are used with bonded sealing washers for exposed roofing and siding applications. The washer helps seal around the fastener head when the screw is installed through metal panels, trim, or flashing.
Proper washer installation matters. The washer should be compressed enough to seal without being overdriven, crushed, or distorted. Overdriving can damage the washer, while underdriving may leave the seal too loose.
How to Choose the Right Fastgrip™ Mechanical Galvanized Roofing Screw
Choose the screw based on the material being fastened, wood substrate, panel thickness, screw diameter, length, washer style, head color, coating, and exposure level. For exposed metal roofing and siding, confirm whether the screw needs a bonded sealing washer and whether the head color should match the panel.
After confirming the screw style, choose the finish that best fits the project. Painted Fastgrip™ screws are useful for visible color-matched installations, while unpainted mechanical galvanized screws are useful when color matching is not required.

Fastgrip™ Mechanical Galvanized Roofing Screw FAQs
What are Fastgrip™ mechanical galvanized roofing screws?
Fastgrip™ mechanical galvanized roofing screws are metal-to-wood roofing fasteners used to attach metal roofing panels, siding panels, trim, flashing, and other metal components into wood purlins, framing, decking, or other wood substrates.
When should I use Fastgrip™ roofing screws?
Use Fastgrip™ roofing screws when fastening metal roofing or siding components into wood. They are commonly used for exposed-fastener roofing, siding, trim, flashing, and other metal-to-wood roofing applications.
What is a Type 17 point used for?
A Type 17 point helps the screw start into wood and can help reduce splitting in many wood fastening applications. It is commonly used on metal-to-wood roofing screws that pass through metal panels before anchoring into wood.
What is the difference between painted and unpainted Fastgrip™ screws?
Painted Fastgrip™ screws are used when the screw head needs to match or complement painted metal roofing panels, siding panels, trim, or flashing. Unpainted Fastgrip™ screws are used when color matching is not needed.
What is the difference between mechanical galvanized and stainless steel Fastgrip™ screws?
Mechanical galvanized Fastgrip™ screws use a galvanized coating, while stainless steel Fastgrip™ screws use stainless material. The right choice depends on the environment, panel material, substrate, corrosion requirements, and project specifications.
Do Fastgrip™ roofing screws need a sealing washer?
Many exposed roofing and siding applications use Fastgrip™ roofing screws with bonded sealing washers. The washer helps seal around the fastener head when installed through metal panels, trim, or flashing.
Can Fastgrip™ roofing screws be used for metal to metal applications?
Fastgrip™ roofing screws are grouped under metal-to-wood roofing screws. For fastening metal roofing components to steel or another compatible metal substrate, use a metal-to-metal roofing screw instead.
How do I choose the right Fastgrip™ roofing screw?
Choose the screw based on the wood substrate, panel thickness, diameter, length, washer style, coating, material, head color, and exposure level. For visible roofing and siding applications, confirm both the fastening performance and the finished appearance before ordering.
