Value Collection 31868 No. 12 Sheet Metal Screw Hex Washer

Product Description

The VALUE COLLECTION 31868 is a No. 12 sheet metal screw designed for fastening sheet metal and light-gauge materials in HVAC, electrical, and general mechanical applications. It features a hex washer head with a slotted drive, a Type AB self-tapping point, and a zinc finish for basic corrosion resistance. The shank measures 1 inch in length under the head. Constructed from Grade 2 steel, this screw delivers reliable holding strength in standard-duty installations. It is sold individually but subject to a minimum order quantity of 50 pieces.

This screw is commonly used in HVAC ductwork assembly, sheet metal enclosure fabrication, electrical junction box mounting, and light structural fastening. The hex washer head provides a large bearing surface that resists pull-through on thin sheet stock, while the slotted drive accommodates both flathead screwdrivers and hex-drive nut drivers. The Type AB point thread form is suited for use in sheet metal, resinous plywood, and some plastics.

Key Features

• No. 12 thread size for high pull-out resistance in sheet metal
• Hex washer head with slotted drive accepts standard nut drivers and screwdrivers
• Type AB self-tapping point for use in sheet metal and light-gauge materials
• 1 inch length under head suits standard sheet metal panel thickness ranges
• Zinc finish provides basic corrosion protection in indoor applications
• Grade 2 steel construction for general-duty mechanical strength

Compatibility

Designed as a standard No. 12 Type AB sheet metal screw suitable for use in residential and light commercial HVAC ductwork, electrical enclosures, and general sheet metal fabrication applications.

Installation Notes

Installation is performed by HVAC technicians, electricians, and sheet metal workers using a hex nut driver or flathead screwdriver. Ensure the receiving material is properly supported before driving to prevent distortion of thin sheet stock. Pre-drilling a pilot hole is not required with Type AB point screws but may be used in harder materials to prevent walking. Follow applicable codes such as the IMC or NEC when fastening ductwork or electrical enclosures.
