Hillman Fasteners 48634 Trim Screw 9x4 in Ceramic Coated 12pk

Product Description

The HILLMAN FASTENERS 48634 is a ceramic coated star drive trim screw designed for exterior trim and finish fastening applications. Measuring 9 x 4 inches, this screw features a 1000-hour ceramic coating that resists corrosion and extends service life in exposed conditions. The star drive recess reduces cam-out during installation, making it a reliable choice for carpenters, siding installers, and general contractors working on trim applications where holding strength and finish appearance both matter. Sold in a box of 12.

This trim screw is suited for residential and light commercial exterior trim work, including fascia, soffit, and decorative board installations. The ceramic coating is particularly relevant in coastal or high-humidity environments where standard fasteners are prone to early corrosion and staining. The 4-inch length provides deep penetration into framing members through standard trim stock. Installers working with composite, PVC, or wood trim materials will find the star drive format reduces tool slippage compared to Phillips or square drive alternatives.

Key Features

• 1000-hour ceramic coating for extended corrosion resistance in exterior applications

Compatibility

Designed as an OEM-style trim fastener suitable for use with wood, composite, and PVC exterior trim materials in residential and light commercial construction.

Installation Notes

Installation is performed by carpenters, siding contractors, or general tradespeople using a star drive bit matched to the screw recess size. Pre-drilling a pilot hole is recommended when fastening near board ends to prevent splitting, particularly in hardwood or composite trim. Follow applicable building codes for exterior fastener corrosion resistance ratings in your climate zone. Do not overdrive — countersink only as deep as needed to maintain trim surface integrity.
