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.

🔍 Which Length Do I Need?

3/4" screws are the OEM standard for most enclosed cargo trailer aluminum skin panels — thin-gauge aluminum over a steel or wood frame. 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. Faster installation, no separate drill step.

✔ Double Square (Robertson No. 2) Drive

Dramatically reduces cam-out vs. Phillips. Fits standard Robertson No. 2 square drive bits — available at any hardware store or included with most screw guns.
