The VALUE COLLECTION SMHWHI0310075B0SL-100BX is a hex washer head sheet metal screw designed for fastening thin metal materials in HVAC, electrical, and general sheet metal fabrication work. This screw features a slotted drive, a Type B point for self-starting into pre-punched or pre-drilled sheet metal, and a zinc finish for corrosion resistance in typical indoor applications. The 5/16 inch thread size and 3/4 inch length under head make it a standard choice for light-gauge metal panel assembly and ductwork connections. It is constructed from Grade 2 steel and ships in a box quantity of 100 screws, ordered in multiples of 10.
This screw is suited for residential and light commercial applications where sheet metal panels, enclosures, HVAC duct components, or electrical cabinets require secure mechanical fastening. The hex washer head provides a broad bearing surface that resists pull-through on thin-gauge material and accepts a standard hex driver or nut driver for installation. Trade professionals including HVAC technicians, sheet metal workers, and electricians commonly use this fastener type when assembling or securing metal panels in the field.
Designed as a standard Type B sheet metal screw for use in pre-punched or pre-drilled light-gauge steel panels and components typical of HVAC ductwork, electrical enclosures, and general sheet metal assemblies.
Installation is performed with a flat-blade screwdriver, hex nut driver, or power driver set to a controlled torque to avoid stripping the slotted drive or the base material. Ensure the receiving material is pre-punched or pre-drilled to the correct diameter for a Type B thread form before driving. Power down all electrical equipment and depressurize any associated systems before fastening panels on live enclosures or HVAC components. Follow applicable codes including NEC and local mechanical codes when securing electrical or HVAC enclosure panels.
