Itw Buildex 560101 Hex Washer Head Sheet Metal Screw 9

Product Description

The ITW BUILDEX 560101 is a No. 9 hex washer head sheet metal screw designed for secure fastening in metal-to-metal and metal-to-substrate applications. Measuring 1-1/2 inches in length under the head, this screw features a hex drive and hex washer head profile that delivers consistent torque transfer and a broad bearing surface to resist pull-through. Constructed from steel, it provides the structural strength required in HVAC, electrical enclosure, and general sheet metal work. Each package contains 100 screws, making it a practical quantity for service techs and installers working production or repetitive fastening tasks.

This screw is suited for residential and light commercial installations where sheet metal panels, ductwork, junction boxes, or equipment housings need to be joined or secured. It is a common fastener in HVAC ductwork assembly, electrical panel work, and mechanical room applications where a reliable hex-drive fastener is required. The hex washer head style is compatible with standard nut drivers and hex sockets, which are tools already carried by most trade professionals.

Installation Notes

Installation is performed by HVAC technicians, electricians, and sheet metal workers using a nut driver or hex-bit driver sized to match the fastener head. De-energize all electrical equipment and shut down any HVAC systems before fastening panels or enclosures. Avoid over-driving, which can strip the sheet metal or damage the fastener head. Follow applicable local codes and manufacturer guidelines for fastener spacing and load requirements.
