Hillman Fasteners 560376 Self-drilling Screw 100 Pack

Product Description

The HILLMAN FASTENERS 560376 is a zinc-plated hex washer head self-drilling screw designed for fast, reliable fastening without a pilot hole. Sold in a 100-pack, the screw measures 1/4-14 x 1 inch, meaning it carries a 1/4-inch major diameter, 14 threads per inch, and a 1-inch length. The hex washer head provides a broad bearing surface and positive drive engagement using a standard hex socket or nut driver. The self-drilling tip bores through light-gauge metal and similar substrates in a single operation, cutting installation time on the job. Zinc plating delivers basic corrosion resistance suitable for interior and sheltered applications. These fasteners are a standard choice for HVAC sheet metal, electrical panel work, and general trade fabrication.

This screw is well suited for light-gauge sheet metal assembly in residential and commercial HVAC ductwork, electrical enclosures, metal framing, and similar trade applications. The self-drilling point eliminates the separate drill step on thin metal stock, making it practical for high-volume fastening tasks where speed matters. The 100-pack quantity supports production installs and service calls alike.

Installation Notes

Install using a hex-head nut driver or socket bit sized for a 1/4-inch hex drive. Power down or de-energize any electrical enclosure or HVAC unit before fastening into panels or covers. Do not overdrive: excess torque can strip the self-drilled thread in thin gauge metal. Follow applicable local codes and manufacturer guidelines for fastener spacing in ductwork and enclosure applications.
