Overview

The NSI Industries QK55M is a zinc-plated steel screw designed for heavy-duty fastening in industrial, construction, and maintenance applications. Measuring 8 x 1/2 inches with a 1/4-inch hex washer head and slotted drive, this screw delivers reliable performance in wood, metal, and composite materials. The sharp point enables self-starting installation, reducing pre-drilling requirements in softer substrates. The integrated washer head distributes clamping force across a larger surface area, preventing pull-through in softer materials like plywood or drywall. The zinc plating provides corrosion resistance, ensuring long-term durability in indoor and outdoor environments. Packaged in bulk (5,000 units per carton), the QK55M is ideal for large-scale projects requiring cost-effective, high-volume fastening solutions. Common applications include HVAC ductwork, electrical enclosures, furniture assembly, and general carpentry. Compatible with standard slotted screwdrivers and compatible with power tools for efficient installation.
