GRK RT Composite Exterior Trim Screws

GRK Fasteners has modified its innovative FIN/TrimTM Head screw to include reverse threading under the head of the fastener. This combination makes the RT Composite Trim Screw the ideal solution for a composite and cellular PVC trim fastener.

• Interior / Exterior Use: No stripping due to six points of contact
• Recessed Star Drive: Eliminates any change of mushrooming
• Trim Head: Presents a clean, finished look
• W-CutTM: Low torque created a smoother drive
• Zip-TipTM: No pre-drilling required means faster penetration
• ESR-3201: Approved for structural application
• Case Hardened Steel: Creates high tensile, torque and shear strength
• ClimatekTM Coating is AC257 code approved for use in treated lumber
• For use in exterior PVC trim (Azek, Kleer, Koma) with no pre-drilling required. ClimatekTM coated fasteners work well with CAMO system. Also great for use in interior applications.
• Available in ClimatekTM or white powder coated finish.
• Also available in PHEINOXTM 305 grade Stainless Steel

Based on extensive tests, data shows that the reverse thread in GRK Fasteners' RT CompositeTM screws help the head disappear beneath the surface of classic wood composite material, eliminating reducing the dimple that can occur when using FIN/TrimTM screws.

RT CompositeTM screws that measure 2" to 3-1/8" in length offer the reverse thread feature, and are available in both regular ClimatekTM coating and in white powder coated finish, perfect for blending into popular white exterior cellular PVC and composite trim.
