Value Collection SMHWI-1201250SL-100BX Sheet Metal Screw

Product Description

The VALUE COLLECTION SMHWI-1201250SL-100BX is a No. 12 sheet metal screw with a hex washer head and slotted drive, sold in a box of 100. Built from Grade 2 steel with a zinc finish, it measures 1.25 inches in length under the head and features a Type AB point for reliable thread engagement in sheet metal and light-gauge materials. The zinc coating provides basic corrosion resistance suitable for general indoor and light-duty applications. Licensed trades and general contractors use these fasteners in HVAC ductwork, electrical enclosures, and light-gauge metal panel assemblies where a hex-drive or slotted driver can be applied.

These screws are commonly used in residential and light commercial construction and service work. Typical applications include securing sheet metal duct sections, attaching junction box covers, fastening metal brackets, and assembling thin-gauge steel components. The hex washer head provides a broad bearing surface that resists pull-through on thin metal. The slotted drive accommodates a flat-blade screwdriver or a slotted hex-washer bit when a power driver is used.

Key Features

• No. 12 thread size for strong holding power in sheet metal and light-gauge steel
• 1.25-inch length under head suits standard sheet metal panel thicknesses
• Type AB point for fast thread engagement without pre-drilling in most light-gauge applications
• Hex washer head distributes clamping load and resists pull-through
• Slotted drive compatible with flat-blade screwdrivers and standard slotted bits
• Zinc finish for basic corrosion resistance in dry or protected environments

Compatibility

Designed as a general-purpose sheet metal fastener for use in light-gauge steel, HVAC ductwork, electrical enclosures, and similar thin-metal assemblies where a No. 12 hex washer head slotted screw is specified.

Installation Notes

These screws are installed by HVAC technicians, electricians, and general sheet metal workers using a flat-blade screwdriver or a slotted hex-washer power bit. Ensure the base material thickness is appropriate for a Type AB point before driving without a pilot hole. De-energize any electrical enclosure or system before fastening covers or panels. Follow applicable codes such as the NEC or SMACNA guidelines for fastener spacing and application requirements.
