Value Collection SMHWI-1200500SL-100BX Sheet Metal Screw No. 12

Product Description

The VALUE COLLECTION SMHWI-1200500SL-100BX is a No. 12 sheet metal screw with a hex washer head and slotted drive, designed for fastening sheet metal and light-gauge materials in mechanical, HVAC, and general trade applications. The screw measures 0.5 inches in length under the head and is manufactured from Grade 2 steel with a zinc finish for corrosion resistance. The Type AB point provides easy thread engagement on pre-punched or drilled holes in thin metal sheet. This box contains 100 screws, suited for high-volume field and shop use by HVAC technicians, sheet metal workers, and general contractors.

No. 12 hex washer head sheet metal screws are a standard fastener in ductwork assembly, equipment panel installation, electrical enclosures, and light structural sheet metal work. The hex washer head combines a built-in washer bearing surface with hex drive geometry, allowing installation with a nut driver, hex bit, or open-end wrench. The slotted drive provides a secondary drive option in tight spaces where a flat-head screwdriver is more practical. These screws are commonly used wherever a secure, removable metal-to-metal connection is needed on thin-gauge sheet stock.

Key Features

• No. 12 thread size for reliable grip in standard sheet metal gauges
• Hex washer head with integrated bearing surface reduces pull-through risk
• Slotted drive accepts flat-blade screwdriver or slotted bit in addition to hex drive
• Type AB point for fast engagement in pre-punched or drilled thin-metal holes
• Zinc finish provides basic corrosion protection for indoor and sheltered installations
• Grade 2 steel construction suitable for light-duty mechanical fastening applications

Compatibility

Designed as a standard No. 12 Type AB sheet metal screw for use in residential and commercial HVAC ductwork, equipment panels, electrical enclosures, and general light-gauge sheet metal assemblies.

Installation Notes

Sheet metal screws of this type are installed by qualified sheet metal workers, HVAC technicians, and electricians following applicable trade codes. Ensure the workpiece is de-energized and secured before fastening in electrical or HVAC panel applications. Use a properly sized hex nut driver or hex bit to avoid stripping the head during installation. Do not overtighten in thin-gauge material, as the hex washer head can deform the substrate if excessive torque is applied.
