Value Collection 31884 Sheet Metal Screw 5/16 Hex Washer 25pk

Product Description

The VALUE COLLECTION 31884 is a 5/16-inch hex washer head sheet metal screw designed for fastening thin metal panels, ductwork, housings, and sheet metal assemblies. The slotted drive accepts a standard flat-blade screwdriver or bit, and the Type AB point self-starts into pre-drilled or punched holes without a separate tapping step. Finished in zinc plating for basic corrosion resistance, this screw is manufactured from Grade 2 steel and measures 1 inch in length under the head. Each package contains 25 screws. HVAC technicians, sheet metal workers, and general tradespeople reach for this fastener in everyday panel and enclosure work.

This screw is suited for light-gauge sheet metal applications common in residential and commercial HVAC installations, electrical enclosures, and general sheet metal fabrication. The hex washer head provides a broad bearing surface that resists pull-through on thin material, while the Type AB thread form bites cleanly into steel sheet. Typical use cases include securing duct sections, equipment access panels, junction box covers, and metal framing components where a reusable, tool-driven fastener is preferred over a self-drilling type.

Key Features

• Type AB point self-starts in pre-drilled or punched sheet metal without a separate tap
• Hex washer head provides a wide bearing surface and reduces pull-through on thin gauges
• Slotted drive compatible with standard flat-blade bits and screwdrivers
• Zinc-plated Grade 2 steel construction for general indoor fastening applications
• 1 inch length under head suits common light-gauge sheet metal stack-ups
• Sold in a 25-screw package for jobsite convenience

Compatibility

Designed as a standard 5/16-inch Type AB sheet metal screw suitable for general light-gauge steel sheet metal fastening applications in HVAC, electrical, and metal fabrication work.

Installation Notes

Sheet metal screws of this type are installed by HVAC technicians and sheet metal workers using a flat-blade screwdriver or a slotted bit in a power driver. Ensure the receiving material is pre-drilled or punched to the correct pilot hole diameter for 5/16-inch Type AB thread engagement before driving. De-energize any electrical equipment and shut down HVAC systems before accessing panels or enclosures. Do not overdrive — excessive torque will strip the thin sheet metal and compromise the fastener hold.
