Most material splitting is prevented because of the TRIM Head screw's exceptionally small head and the W-Cut thread design. The RT screws include a reverse threading under the head of the fastener. GRK has found that the reverse thread helps the screw head disappear beneath the surface of the classic wood composite material, reducing or eliminating the dimple that sometimes appears. Some sizes are available in PHEINOX Stainless Steel. ## Features - Specially designed for attaching composite and cellular PVC materials - Underhead reverse thread reduces or eliminates mushrooming - Trim Head for a clean finished look - For interior/exterior use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001SFFB4G | | Best Sellers Rank | #67,233 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #638 in Wood Screws | | Brand | GRK | | Color | Gold | | Customer Reviews | 4.6 4.6 out of 5 stars (253) | | Drive System | Torx | | Exterior Finish | Climatek | | Fastener Size | #8 x 2-1/2" | | Fastener Type | Deck Screws | | Finish Types | Coated | | Global Trade Identification Number | 00772691160799 | | Head Type | Trim | | Included Components | GRK FASTENERS 16079 RT COMPOSITE #8 x 2-1/2" SCREWS 605CT | | Item Diameter | 0.16 Inches | | Item Dimensions | 6 x 5 x 5 inches | | Item Type Name | GRK FASTENERS 16079 RT COMPOSITE #8 x 2-1/2" SCREWS 605CT | | Item Weight | 0.15 Pounds | | Manufacturer | GRK | | Material Type | Steel | | Metal Type | Alloy Steel | | Model | 772691160799 | | Number Of Items | 1 | | Number of Pieces | 605 | | Part Number | 772691160799 | | Screw Head Style | Trim | | Screw Point Style | Type A Point | | Set Screw Thread Type | Reverse | | Size Name | 8" | | Thread Coverage | Threaded at one end | | Thread Size | #8 | | Thread Style | Reverse Thread | | Thread Type | Reverse | | UPC | 772691160799 | | Unit Count | 605.0 Count | ## Product Details - **Exterior Finish:** Climatek - **Head Style:** Trim - **Item dimensions L x W x H:** 6 x 5 x 5 inches - **Material:** Steel - **Thread Size:** #8 ## Images ![GRK FASTENERS 16079 RT COMPOSITE #8 x 2-1/2" SCREWS 605CT - Image 1](https://m.media-amazon.com/images/I/51zE6+PkMpL.jpg) ![GRK FASTENERS 16079 RT COMPOSITE #8 x 2-1/2" SCREWS 605CT - Image 2](https://m.media-amazon.com/images/I/71D4ZO5tM4L.jpg) ![GRK FASTENERS 16079 RT COMPOSITE #8 x 2-1/2" SCREWS 605CT - Image 3](https://m.media-amazon.com/images/I/81wfwxfQbFL.jpg) ![GRK FASTENERS 16079 RT COMPOSITE #8 x 2-1/2" SCREWS 605CT - Image 4](https://m.media-amazon.com/images/I/61S4+dtJFQL.jpg) ## Available Options This product comes in different **Size** options. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.es/products/160154765-grk-fasteners-16079-rt-composite-8-x-2-1-2](https://www.desertcart.es/products/160154765-grk-fasteners-16079-rt-composite-8-x-2-1-2) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-07-15*
