Value Collection 0412MSP 4-40 Pan Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 0412MSP is a 4-40 unified coarse thread machine screw with a pan head and slotted drive, manufactured from steel with a zinc finish. It measures 0.75 inches in length under the head and conforms to ASME B18.6.3 and SAE J82 standards. The zinc coating provides basic corrosion resistance for general indoor fastening applications. This screw is a standard inch-series fastener used by electricians, HVAC technicians, panel fabricators, and general tradespeople for light-duty assembly and component mounting tasks.

The 0412MSP is suited for light-gauge metal assemblies, electrical enclosures, control panel interiors, junction boxes, and similar applications where a small-diameter threaded fastener is required. The pan head profile provides a low-profile bearing surface and is compatible with standard slotted screwdrivers. It is sold in multiples of 100 pieces minimum order quantity, making it appropriate for shop stock, service van inventory, or production assembly use.

Key Features

• 4-40 unified coarse thread for reliable engagement in tapped holes and threaded inserts
• Pan head profile distributes clamping load across a wider bearing surface than flat head styles
• Slotted drive accepts standard flat-blade screwdrivers
• Steel construction with zinc finish for general-purpose indoor corrosion resistance
• Conforms to ASME B18.6.3 and SAE J82 dimensional and material standards
• Inch-system fastener with 0.75-inch length measured under the head

Compatibility

Designed as a standard 4-40 inch-series machine screw for use in any application requiring an ASME B18.6.3-compliant pan head slotted fastener in steel with zinc finish.

Installation Notes

Install using a flat-blade screwdriver sized to fit the slotted drive without slipping to avoid cam-out and head damage. Ensure the mating tapped hole or threaded insert is clean and free of debris before driving. Do not overtorque small-diameter machine screws, as steel threads in light-gauge materials can strip with excessive force. Follow applicable assembly or electrical enclosure standards when using this fastener in code-governed installations.
