Value Collection -31859-3/4 No. 8 Sheet Metal Screw

Product Description

The VALUE COLLECTION -31859-3/4 is a No. 8 sheet metal screw designed for light-gauge metal fastening applications. It features a hex washer head with a slotted drive and a Type AB point for self-starting penetration into sheet metal, thin steel panels, and similar substrates. The screw measures 3/4 inches in length under the head. Constructed from Grade 2 steel with a zinc finish, it offers baseline corrosion resistance suitable for general indoor mechanical and electrical enclosure assembly. HVAC technicians, electricians, and sheet metal workers use this fastener for securing ductwork flanges, panels, and access covers.

This screw is suited for residential and light commercial trade applications where a standard No. 8 hex washer head sheet metal fastener is required. The slotted drive accommodates a flat-blade screwdriver or hex driver, and the Type AB thread form is compatible with light-gauge ferrous sheet metal. Sold in a minimum order quantity of 50 pieces per package, this fastener is a practical stocking unit for service vehicles, panel shops, and maintenance operations.

Compatibility

Designed as a standard No. 8 Type AB sheet metal screw for use in light-gauge ferrous sheet metal, ductwork panels, electrical enclosures, and similar thin-metal assemblies.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or electricians using a flat-blade screwdriver or a hex driver bit. Confirm the base material gauge is appropriate for a No. 8 Type AB thread form before driving. Do not overdrive hex washer head screws, as excessive torque can strip the thread engagement in thin sheet metal. Follow applicable NEC or SMACNA guidelines when fastening electrical or ductwork panels.
