Hillman Fasteners 47227 Self-drilling Screw 1/4x2 in Box 12

Product Description

The HILLMAN FASTENERS 47227 is a zinc-plated hex washer head self-drilling screw designed for fast, reliable fastening in metal-to-metal and metal-to-substrate applications. At 1/4 inch diameter and 2 inches in length, this screw combines a built-in drill point with a hex washer head, eliminating the need for a separate pilot hole. The zinc coating provides basic corrosion resistance for general interior and exterior applications. Sold in a box of 12, this fastener is a standard choice for contractors, HVAC installers, and sheet metal fabricators working in commercial and light industrial settings.

Self-drilling screws of this size and head style are commonly used in HVAC ductwork assembly, metal stud framing, electrical enclosure mounting, and general sheet metal work. The hex washer head allows for consistent torque application with a nut driver or hex-drive bit, making installation faster on production or repetitive-fastening tasks. These screws are suited for residential and light commercial projects where a pre-drilled pilot hole is not practical or desired.

Key Features

• 1/4 inch diameter by 2 inch length — suitable for moderate-depth metal fastening applications
• Self-drilling point eliminates the need for a pre-drilled pilot hole
• Hex washer head provides a wide bearing surface and consistent drive engagement
• Zinc plating offers corrosion resistance for general-purpose use
• Box of 12 — practical quantity for small jobs or field repairs

Compatibility

Designed as a general-purpose self-drilling fastener suitable for metal-to-metal and light metal-to-substrate applications where a 1/4 inch hex washer head drive style is required.

Installation Notes

Install using a hex-drive nut driver or impact driver set to a controlled torque to avoid stripping the head or overdriving into thin material. Power down or de-energize any equipment in the work area before fastening near electrical components or live panels. Follow applicable local building codes and manufacturer specifications for fastener spacing and load requirements. Do not use these screws as structural anchors unless confirmed compatible with the substrate and load rating by a qualified professional.
