Itw Buildex 560105 Hex Washer Head Sheet Metal Screw

Product Description

The ITW BUILDEX 560105 is a No. 9 hex washer head sheet metal screw designed for reliable fastening in light-gauge metal applications. Measuring 1 inch in length under the head, this screw features a hex drive for positive wrench engagement and reduced cam-out during installation. Constructed from steel, it delivers consistent holding strength in metal-to-metal and metal-to-substrate connections. Each package contains 100 screws, making it practical for production work, service calls, and job-site restocking. This fastener is a standard choice for HVAC, electrical enclosure, and sheet metal fabrication work.

This screw is suited for residential and commercial applications where sheet metal panels, ductwork, junction boxes, and metal framing components require secure mechanical fastening. The hex washer head provides a wide bearing surface that distributes clamping load and resists pull-through in thin-gauge sheet metal. The hex drive accepts standard nut drivers and hex bit drivers, which are common tools across HVAC, electrical, and general sheet metal trades. Sold in a 100-count package to support higher-volume installation tasks.

Key Features

Compatibility

Designed as an OEM-style replacement and general-use fastener for sheet metal assemblies requiring a No. 9 hex washer head screw with a 1-inch length under head.

Installation Notes

Installation is typically performed by HVAC technicians, electricians, and sheet metal fabricators using a standard nut driver or hex-bit driver. Power down all electrical equipment and de-energize any associated systems before fastening near live components. Use a driver with controlled torque settings to avoid stripping the material or over-driving the screw into thin-gauge sheet metal. Always follow applicable local codes and manufacturer assembly guidelines for the equipment or enclosure being serviced.
