Value Collection 31877 Sheet Metal Screw 1/4 in Hex Washer

Product Description

The VALUE COLLECTION 31877 is a 1/4-inch hex washer head sheet metal screw designed for fastening sheet metal and light-gauge material in HVAC, electrical, and general trade applications. The slotted drive accepts a standard flat-blade screwdriver or bit. The Type AB point provides self-starting penetration into pre-punched or pre-drilled sheet metal without requiring a separate tapping step. Finished in zinc for basic corrosion resistance, this Grade 2 steel screw measures 1-1/2 inches in length under the head and is sold in a minimum order quantity of 25 pieces.

This screw is suited for light-duty sheet metal assembly work common in residential and commercial HVAC ductwork, electrical enclosures, and equipment panels. The hex washer head provides a broad bearing surface that resists pull-through on thin-gauge sheet metal. HVAC technicians, sheet metal workers, and electricians routinely use this fastener when securing duct sections, access panels, and junction box covers. The slotted hex washer configuration allows driving with either a nut driver or a flat-blade bit, offering flexibility on the job.

Key Features

• Type AB point for self-starting entry into sheet metal without pre-tapping
• Hex washer head style provides wide bearing surface and reduces pull-through
• Slotted drive accepts flat-blade screwdriver or standard flat bit
• Grade 2 steel construction for reliable mechanical strength in light-duty applications
• Zinc finish offers basic corrosion protection in dry indoor environments
• 1-1/2 inch length under head suits standard sheet metal panel thicknesses

Compatibility

Designed as a standard 1/4-inch Type AB sheet metal screw suitable for use in light-gauge sheet metal assemblies including HVAC ductwork, electrical enclosures, and equipment access panels.

Installation Notes

Sheet metal screws of this type are installed by HVAC technicians, sheet metal workers, and electricians as part of routine panel and duct assembly. De-energize all electrical equipment and shut down HVAC systems before fastening enclosures or panels. A nut driver or flat-blade bit at the appropriate torque setting prevents stripping the slotted drive. Follow applicable SMACNA, NEC, or local mechanical codes for fastener spacing and installation requirements.
