Value Collection 31872 Hex Washer Sheet Metal Screw 1/4in

Product Description

The VALUE COLLECTION 31872 is a 1/4-inch hex washer head sheet metal screw designed for fastening sheet metal and light-gauge materials in trade and industrial applications. The slotted drive accepts a standard flat-blade driver or bit. Made from Grade 2 steel with a zinc finish, this screw resists corrosion in typical indoor and light-duty environments. The Type AB point self-starts in pre-punched, pre-drilled, or self-drilling applications on thin sheet metal. At 3/4 inch length under head, it is suited for shallow-material fastening tasks common in HVAC ductwork assembly, electrical enclosures, and sheet metal fabrication.

This screw is used in residential and commercial trade work wherever light-gauge sheet metal panels, brackets, or enclosures need to be joined or secured. HVAC installers commonly use hex washer head sheet metal screws for duct assembly, access panel attachment, and equipment cabinet work. Electricians use them for metal enclosure and junction box assembly. The hex washer head provides a broad bearing surface that resists pull-through on thin-gauge material, and the slotted drive allows use with basic hand tools or power drivers.

Key Features

• Type AB point self-starts in pre-punched or thin-gauge sheet metal without a separate pilot hole in many applications
• Hex washer head provides a wide bearing surface to resist pull-through on light-gauge material
• Slotted drive compatible with standard flat-blade screwdrivers and bits
• Grade 2 steel construction for reliable strength in standard fastening applications
• Zinc finish provides corrosion resistance for typical indoor and sheltered installations
• 3/4 inch length under head suits shallow-stack sheet metal joints common in HVAC and electrical work

Compatibility

Designed as a standard 1/4-inch Type AB sheet metal screw for use in light-gauge steel sheet metal applications typical of HVAC ductwork, electrical enclosures, and general sheet metal fabrication.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or electricians using a flat-blade screwdriver or hex-drive power tool. De-energize any electrical enclosure or HVAC system before fastening or removing screws on live equipment panels. Avoid overtightening, which can strip the threads in light-gauge material or deform the washer head seating surface. Follow applicable codes such as SMACNA standards for duct assembly or NEC requirements for electrical enclosure work.
