The MALCO 55467 is a pack of 100 hex head self-tapping sheet metal screws in a 10-16 x 3/4 inch configuration. These screws are designed to drive into sheet metal without a pre-tapped hole, using a sharp point and aggressive thread pitch to create their own thread on penetration. The hex head format allows fast installation with a nut driver or hex-drive bit. This pack format reduces restocking trips during high-volume jobs and keeps installation moving. HVAC installers and sheet metal workers will recognize this as a standard fastener for duct assembly, equipment panels, and enclosure work.
These screws are suited for light-gauge sheet metal applications common in residential and commercial HVAC ductwork, air handler enclosures, equipment cabinets, and similar fabrication and service work. The 10-16 thread designation indicates a No. 10 diameter with 16 threads per inch, appropriate for joining sheet metal panels and thin-gauge steel components. The 3/4 inch length provides adequate thread engagement without excessive protrusion on standard-gauge sheet metal.
Designed as a standard self-tapping hex head screw for light-gauge sheet metal applications including HVAC ductwork, equipment panels, and metal enclosures.
Sheet metal screws of this type are typically installed by HVAC technicians and sheet metal workers using a nut driver or drill with a hex-drive bit. Avoid overdriving, which can strip threads in thin-gauge material or distort the panel. Ensure the base material gauge is appropriate for the 10-16 thread pitch before driving. No special tools or permits are required for standard fastener installation.
