Value Collection SMPPI0-400250-100BX Sheet Metal Screw 100pk

Product Description

The VALUE COLLECTION SMPPI0-400250-100BX is a No. 4 pan head sheet metal screw with a Phillips drive, sold in a box of 100. The screw measures 1/4 inch in length under the head and is manufactured from Grade 2 steel with a zinc finish. The Type AB point allows for self-starting in thin sheet metal, light-gauge steel, and similar substrates without a pre-drilled pilot hole in many applications. The zinc finish provides basic corrosion resistance in standard indoor and sheltered environments. These fasteners are sized for light-duty mechanical assembly work across HVAC, electrical, and general sheet metal fabrication.

This screw is suited for securing sheet metal panels, duct covers, electrical enclosures, access doors, and similar thin-gauge metal components. Its compact 1/4-inch under-head length makes it appropriate for shallow-depth applications where a longer fastener would bottom out or pierce through. HVAC technicians, electricians, and sheet metal workers commonly use No. 4 pan head screws in cabinet assembly, equipment enclosures, and field fabrication tasks.

Key Features

• Type AB point for self-starting in thin sheet metal without a pre-drilled pilot hole in most applications
• Pan head profile provides a broad bearing surface and low-profile sit against the workpiece
• Phillips drive compatible with standard and powered screwdrivers
• Grade 2 steel construction with zinc finish for basic corrosion resistance
• 1/4-inch length under head suits shallow-depth sheet metal fastening
• Box quantity of 100 supports production and service work without frequent reordering

Compatibility

Designed for use in thin sheet metal, light-gauge steel panels, and similar substrates typical of HVAC equipment, electrical enclosures, and general sheet metal fabrication assemblies.

Installation Notes

Installation is performed with a Phillips-tip screwdriver or a powered driver set to an appropriate clutch setting to avoid stripping the head. Power down and de-energize any electrical enclosure or HVAC unit before fastening panels or covers. Avoid over-torquing, which can strip the thread form in thin-gauge material or crack the head. Follow applicable codes such as the NEC or local mechanical codes when securing electrical or HVAC enclosure panels.
