Value Collection 31942 5/16 Hex Head Sheet Metal Screw 25-pack

Product Description

The VALUE COLLECTION 31942 is a 5/16 inch hex head sheet metal screw designed for fastening into sheet metal, light-gauge steel, and similar thin-material assemblies. The hex drive and hex head profile allow for high-torque installation using a standard nut driver or socket. At 1/2 inch in length under head, this screw is suited for thin-stack applications where thread engagement must be precise and positive. The Type AB point self-starts into pre-drilled or punched pilot holes without requiring a separate tapping step. Made from Grade 2 steel with a zinc finish, this fastener offers basic corrosion resistance appropriate for indoor and light-exposure applications. Sold in a pack of 25.

These screws are commonly used in HVAC ductwork assembly, electrical enclosures, light-gauge metal framing, and general sheet metal fabrication. HVAC technicians, sheet metal workers, and electricians use this type of fastener when securing panels, covers, and flanged connections in both residential and light commercial installations. The compact 1/2 inch under-head length makes them well suited for thin sheet metal gauges where a longer fastener would bottom out or over-penetrate.

Key Features

• 5/16 inch thread size with hex head for high-torque nut driver or socket installation
• 1/2 inch length under head for precise engagement in thin-gauge sheet metal
• Type AB point self-starts in pre-drilled or punched pilot holes
• Hex drive matches hex head, allowing single-tool installation
• Zinc finish provides basic corrosion resistance for indoor and light-exposure use
• Grade 2 steel construction for standard load-bearing fastener applications

Compatibility

Designed as a standard Type AB sheet metal screw suitable for use in light-gauge steel, sheet metal ductwork, electrical enclosures, and general thin-material metal assemblies where a 5/16 inch hex head fastener is specified.

Installation Notes

Installation is performed using a nut driver or socket sized for a hex head fastener. Ensure the correct pilot hole diameter is used for the 5/16 inch thread to avoid stripping the parent material. Power down or de-energize any electrical enclosure or HVAC unit before fastening panels or covers. Do not overtighten into thin sheet metal, as thread stripping can occur in light-gauge stock.
