## Overview

The GRK 45079 RT Trim #8 by 2-1/2-inch PHEINOX 316 Stainless Steel Marine Grade Fasteners come in a bulk box of 3,500 screws, designed for superior performance in seaside construction. These self-tapping, trim head screws feature a w-cut thread design and reverse threads to eliminate mushrooming, making them ideal for composite decking and wood applications.

## Description

GRK RT trim head screws have the smallest screw head available and work great for most fine carpentry applications. 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.

## Features

- 316 stainless Steel for the ultimate performance in all seaside construction
- Uses GRK T10 bit
- Reverse Threads for composite decking eliminate mushrooming
- Self-tapping, trim head screws; w-cut thread design
