Collection: Metal To Metal Self-Drilling Roofing Screws

Lock Metal Panels to Steel That Holds

When you're fastening straight into structural steel, you need a screw engineered for the job. Our metal-to-metal roofing screws bite through steel roofing, siding, and panels for a strong, leak-resistant hold that stands up to high-stress conditions. A self-drilling tip powers through metal with no pre-drilling for fast, precise installation, while anti-corrosion coatings fight rust so your connections last through the harshest weather.

Why Choose Metal-to-Metal Roofing Screws from EcoFoil?

In construction and agriculture, a roof is only as secure as its fasteners. These screws deliver the durable, weather-tight connections that barns, stables, warehouses, and other steel-framed buildings depend on. Self-drilling points cut installation time, aggressive threads grip firmly against high winds and driving rain, corrosion-resistant finishes hold up in every climate, and a full range of lengths and diameters means there's a match for whatever gauge you're working with. Driven correctly, they clamp roofing and sidewall panels into a waterproof seal that keeps leaks out and rust at bay.

Maxx Steelbinder — Powers Through Thick Steel

A #12 screw with a 5/16" cupped hex washer head. Its self-drilling MicroBit point drives into steel up to .210" thick, and the EPDM washer holds a secure seal even on an angled drive. Reach for the Maxx Steelbinder 7/8" stitch screws to lock overlapped panels together and to fasten metal roof pipe boots.

ZXL Steelbinder — Lifetime Rust Protection, 40-Year Warranty

A #12 screw with a 5/16" cupped hex washer head cast from ZAMAC 5 zinc-aluminum alloy for lifetime protection against red rust, backed by a 40-year warranty. The washer face captures the EPDM washer for a waterproof seal, making it a strong match for metal roof panels and silicone pipe flashing boots. Install with a spring-loaded nutsetter.

Eclipse Steelbinder — Smooth, Low-Profile Finish

A #12 truss-head screw driven with a T30 6-lobe recess for a clean, low-profile look. It's built for sidewall metal in animal shelters, where its smooth finish won't scratch or tear hide. Install with a T30 6-lobe driver bit.

HG Steelbinder — Maximum Pull-Out Strength.

A #12-24 heavy-gauge screw with a 5/16" hex washer head, made for steel from .210" to .500" thick. Engineered for maximum pull-out strength, it's the right call for metal decks and structural steel attachment.

ZXL HG Steelbinder — Heavy-Gauge Strength That Won't Rust

A #12-24 heavy-gauge screw with a 5/16" cupped hex washer head in ZAMAC 5 zinc-aluminum for lifetime rust protection and added strength, backed by a 40-year warranty. It anchors metal roof panels to structural steel joists from .210" to .500" thick, and the head and washer face capture the EPDM washer securely even at an angle. Install with a spring-loaded nutsetter.

Tapping Steelbinder — The Rescue Screw

Designed to attach metal roofing and siding to metal purlins, and equally at home as a rescue screw that replaces loosened fasteners in older structures.

What Makes Steelbinder Screws Perform

Every Steelbinder screw is built around a self-drilling point that penetrates metal cleanly without pre-drilling to cut installation time. Zinc-plated coatings guard against rust to extend life in harsh conditions, high-tensile construction handles heavy loads across roofing, siding, and structural work, and aggressive threading grips metal tightly so screws won't back out over time. Paired with sealing washers, they shut out leaks and moisture to protect the integrity of your roof.

How to Choose the Right Screw

Start with the gauge of your roofing, and match screw length and diameter to the panel thickness. Confirm your substrate as well: these screws are made strictly for metal-to-metal applications, and metal-to-wood jobs call for a different fastener. In high-humidity or saltwater environments, choose a high-corrosion-resistance option so the elements don't cut your connections short.

Install Right and Keep It Tight

Use a screw gun with a depth-sensing nosepiece to seat each screw to the correct depth; pre-drilling is optional and generally unnecessary. Test a screw or two before you commit to confirm your drill setting is dialed in, then inspect periodically and replace any worn fasteners to keep the structure sound.

Pair with the Right Accessories

Set yourself up with the right tools and sealants: a spring-loaded socket nutsetter, required for ZXL and ZXL HG Steelbinders because of their aluminum coating; a magnetic socket nutsetter that works with every metal-to-metal screw except the ZXL and Eclipse; a T30 6-lobe driver bit for smooth, low-profile driving of Eclipse Steelbinders; NovaFlex Silicone Metal Roof Sealant for added protection at joints and fasteners; and metal roof boots to seal pipe penetrations for a fully watertight roof.
