Value Collection 40776 Sheet Metal Screw 8 X 3/4 in 100 Pk

Product Description

The VALUE COLLECTION 40776 is a No. 8 pan head sheet metal screw with a square drive recess, designed for fastening light-gauge sheet metal, HVAC ductwork, electrical enclosures, and similar thin-material assemblies. Made from Grade 2 steel with a zinc-plated finish, these screws measure 3/4 inches in length under the head and use a Type AB point for easy thread engagement in pre-drilled or self-piercing applications. Sold in a 100-count pack, they are a standard fastener for trade work where consistent, corrosion-resistant fastening is required.

These sheet metal screws are commonly used by HVAC technicians for duct assembly and panel fastening, electricians for securing electrical enclosures and junction box covers, and plumbers for light sheet metal brackets and supports. The square drive reduces cam-out during installation, making them well suited for production or repetitive fastening tasks. The pan head profile provides a wide bearing surface without sharp edges, appropriate for exposed or semi-exposed installations.

Key Features

• No. 8 thread size with Type AB point for reliable engagement in sheet metal
• 3/4 inch length under head suits standard light-gauge sheet metal applications
• Square drive recess reduces cam-out compared to slotted or Phillips drive
• Grade 2 steel construction with zinc-plated finish for corrosion resistance
• Pan head profile provides broad clamping surface on thin materials
• 100-count pack supports high-volume trade and service work

Compatibility

Designed as a standard No. 8 x 3/4 inch Type AB sheet metal screw suitable for light-gauge steel ductwork, electrical enclosures, HVAC equipment panels, and similar thin-metal fastening applications.

Installation Notes

Installation is performed by HVAC technicians, electricians, and general trade professionals using a square-drive bit and power screwdriver or hand driver. Confirm the correct drill or pilot hole size for the gauge of material being fastened before driving. Do not overdrive screws into thin sheet metal, as stripping threads reduces holding strength. Follow applicable codes such as SMACNA standards for duct assembly when used in HVAC ductwork applications.
