OEM-Grade Exterior Panel Fasteners — Sold by the Pound Secure trailer siding panels with confidence using these OEM-grade #10 double square self-tapping screws — the same fastener used by Forest River, Cargo Mate, AmeraLite, and most major enclosed trailer manufacturers. Available in 3/4" and 1" lengths, and six panel-matching colors. These screws are self-drilling — the fluted tip bores its own pilot hole through aluminum or thin-gauge steel siding without pre-drilling. The double square (Robertson No. 2) recess delivers excellent torque transfer with virtually zero cam-out, making them significantly faster to drive than Phillips-head alternatives. 📐 Specifications Specification 3/4" Length 1" Length Screw Size #10 Drive Type Double Square (Robertson No. 2) Point Type Self-Drilling (Type 17 fluted tip) Finish Zinc Plated — corrosion resistant Head Style Truss / Modified Pan Head Package Weight 1 lb Est.

This is the most common size for standard panel replacement or repair. 1" screws are used where extra bite is needed: thicker composite panels, corrugated aluminum siding, or heavier-gauge steel framing. Also commonly used in floor-to-wall transition trim installation. When in doubt, check the screws you're replacing — the length is stamped or printed on the head or packaging. Most Forest River, Cargo Mate, and AmeraLite trailers use 3/4". 🎨 Color Matching Guide Select the color that matches your trailer's exterior panel color for a factory-finish appearance: Black — Standard black aluminum skin trailers; most cargo trailers White — White panel enclosed trailers, horse trailers, cargo vans Steel — Brushed aluminum / natural metal finish panels Dove Gray — Light gray exterior panels; common on Forest River units Silver Frost — Bright silver finish panels; AmeraLite and similar Charcoal — Dark gray / charcoal exterior panels 💪 Key Features ✔ Self-Drilling — No Pre-Drilling Required Fluted tip cuts through aluminum and light-gauge steel siding on contact.
