Value Collection SMHWI-1203000SL-100BX Sheet Metal Screw

Product Description

The VALUE COLLECTION SMHWI-1203000SL-100BX is a No. 12 sheet metal screw with a hex washer head and slotted drive, designed for fast, reliable fastening in light-gauge metal applications. The screw measures 3 inches in length under the head and features a Type AB point for easy thread engagement in pre-punched or self-drilled holes. Constructed from Grade 2 steel with a zinc finish, it resists corrosion in typical indoor and light-duty outdoor service environments. This box contains 100 screws. HVAC technicians, electricians, and sheet metal workers reach for this fastener size regularly when assembling ductwork, panels, and equipment enclosures.

No. 12 hex washer head sheet metal screws are a standard fastener in HVAC duct fabrication, electrical enclosure assembly, and general sheet metal work. The hex washer head provides a broad bearing surface that resists pull-through in thin-gauge material, while the slotted drive allows installation with a standard flat-blade bit or driver. The Type AB point thread form is suited for low-carbon steel sheet, light aluminum, and similar thin-gauge substrates commonly encountered in residential and light commercial mechanical installations.

Key Features

• No. 12 thread size with Type AB point for positive engagement in thin-gauge metal
• 3-inch length under head suits thicker stack-ups and layered sheet metal assemblies
• Hex washer head provides wide bearing surface and reduces pull-through risk
• Slotted drive compatible with standard flat-blade bits and manual screwdrivers
• Grade 2 steel construction with zinc finish for corrosion resistance in typical service conditions
• Box of 100 supports production or service work without frequent restocking

Compatibility

Designed as a standard No. 12 Type AB sheet metal screw suitable for light-gauge steel sheet, HVAC ductwork panels, electrical enclosures, and similar thin-metal fastening applications.

Installation Notes

Sheet metal screws of this type are installed by HVAC technicians, electricians, and general sheet metal tradespeople using a hex-head driver or flat-blade bit rated for the drive size. Pre-punch or pre-drill pilot holes in the substrate where required by the material gauge to prevent distortion. Avoid overtorquing, which can strip the thread engagement in thin material or deform the washer head bearing surface. Follow applicable mechanical and building codes for fastener spacing and pull-out requirements in duct and enclosure assemblies.
