Overview

The Minerallac 78812-2500 is a high-efficiency 8-18 x 3/4" Hex Washer Head TEK (self-drilling) sheet metal screw designed for rapid metal-to-metal fastening in electrical and mechanical installations. This zinc-plated fastener features a #2 drill point for self-starting capability, eliminating the need for pre-drilled holes in sheet metal up to 18-gauge thickness. The hex washer head provides an increased bearing surface area, distributing torque evenly and reducing the risk of pull-through in thin materials. Supplied in a bulk box of 2,500 units, this SKU is optimized for high-volume applications where speed and reliability are critical. Typical uses include panel mounting, conduit attachment, HVAC ductwork, and light-duty structural assemblies. The zinc plating offers basic corrosion resistance suitable for indoor environments, making it a cost-effective solution for general-purpose fastening tasks. Compatible with standard 1/4" hex drivers, these screws install quickly with minimal tooling requirements, reducing labor time in assembly operations. The self-drilling design minimizes secondary operations, streamlining workflows in production environments. For applications requiring stainless steel corrosion resistance, refer to Minerallac’s 18-8 stainless steel TEK screw variants.
