Metal Roofing Screws 3in #10, 320-PCS - Ruspert Rust Protection

Our review of these metal roofing screws focuses on durability and everyday usefulness for DIYers and contractors. The 320-PCS pack of #10 x 3in screws stood out primarily for its long-term corrosion protection thanks to the Ruspert coating, which the manufacturer says passes a 1500-hour salt spray test; that single advantage makes them a sensible choice for outdoor roofing and siding projects where rust is a concern. The set also includes a magnetic hex socket and a plastic storage box, which adds practical value for on-site work.

Key Features

• Ruspert anti-corrosion coating: Provides extended rust resistance, useful for exposed roofing and siding in coastal or wet climates.
• Self-drilling sharp point: The drill tip and high-low thread design let the screws penetrate metal and wood without pre-drilling for faster installation.
• EPDM rubber washer with stainless ring: Offers a tight, leak-proof seal and added corrosion resistance around fastener penetrations.
• Convenient kit packaging: Comes with 320 screws, a 5/16in magnetic hex socket, and a plastic storage box to keep fasteners organized on the job.
• Versatile application: Suitable for metal roofing panels, corrugated roofing, tin sheds, pole barns, and attaching metal to wood or metal.

Who It's For

These screws are aimed at homeowners doing roof or siding repairs, small contractors, and hobbyists working on outbuildings who need a reliable, rust-resistant fastener that reduces the need for pre-drilling. The included magnetic hex socket and storage box make it convenient for people who work with power tools and want a ready-to-use kit.

Those who should look elsewhere are professionals needing specialty fasteners beyond #10 x 3in or stainless steel fasteners for guaranteed lifetime corrosion immunity, and projects that demand exacting structural specifications where engineered fasteners with certified load ratings are required.

Pros & Cons

Pros

• Durable Ruspert coating that delivers long-lasting rust protection for outdoor use.
• Sharp, self-drilling point and high-low threads that speed installation without pre-drilling in many cases.
• EPDM washer with stainless steel support that improves water sealing and corrosion resistance.
• The kit includes a magnetic hex socket and a plastic box, which adds practical convenience on site.

Cons

• Some buyers report mixed impressions about sharpness, so performance can vary with very thick steel or dense timbers.
• Not marketed as full stainless steel fasteners, so extreme marine environments may still require different materials.
