Value Collection 40786 Pan Head Sheet Metal Screw No. 11

Product Description

The VALUE COLLECTION 40786 is a No. 11 pan head sheet metal screw designed for fastening thin metal panels, ductwork, enclosures, and related light-gauge steel assemblies. It features a square drive recess, a Type AB point for thread-forming entry into pre-punched or drilled sheet metal, and a zinc finish for basic corrosion resistance. Measuring 1.25 inches under the head, it is fabricated from Grade 2 steel and sold in multiples of 50. HVAC technicians, electricians, and sheet metal workers routinely specify this screw type for securing equipment panels, junction boxes, and duct connections.

This screw is suited for light-gauge sheet metal applications in both residential and commercial settings. Typical uses include securing HVAC cabinet panels, equipment enclosures, electrical boxes, and duct sections where a flush-sitting pan head profile is required. The square drive reduces cam-out during installation, making it a practical choice for high-volume fastening tasks on the job site or in a fabrication shop.

Key Features

• No. 11 thread size for light-gauge sheet metal fastening
• Pan head profile sits low and distributes clamping load across a wider bearing surface
• Square drive recess minimizes cam-out under power tool torque
• Type AB point self-starts in pre-punched or drilled holes without a pilot tap
• Zinc finish provides basic protection against oxidation in dry indoor environments
• Grade 2 steel construction suits standard light-duty sheet metal assembly

Compatibility

Designed as a standard No. 11 pan head Type AB sheet metal screw suitable for light-gauge steel panels and enclosures typical in HVAC, electrical, and general sheet metal fabrication applications.

Installation Notes

Sheet metal screws of this type are installed by HVAC technicians, electricians, and sheet metal workers using a square-drive bit in a power drill or impact driver. De-energize and lock out any electrical or mechanical equipment before fastening panels to energized enclosures or live duct systems. Ensure the receiving material is pre-punched or drilled to the correct pilot hole diameter for a No. 11 Type AB point before driving. Do not overtorque, as stripping is possible in thin-gauge material.
