Overview

The Minerallac Company 79240 is a #12-14 x 2-1/2" Hex Washer Head Tek Screw, zinc-plated for corrosion resistance. These self-starting screws feature a sharp tek point for direct penetration into metal substrates without pre-drilling. The hex washer head design ensures even clamping force distribution, preventing material damage and ensuring a secure connection. Constructed from zinc-plated steel, these fasteners offer protection against rust and corrosion, making them suitable for indoor and protected outdoor applications. With a #12-14 thread size and a 2.5-inch length, they are ideal for a range of construction tasks including framing, decking, and mounting electrical boxes. The hex drive head is compatible with standard hex or impact drivers, reducing the likelihood of cam-out compared to Phillips-head fasteners. Manufactured in the US.
