Value Collection 0407MSP 4-40 X 7/16 in Pan Head Slotted Screw

Product Description

The VALUE COLLECTION 0407MSP is a 4-40 pan head machine screw designed for light-duty fastening applications in mechanical assemblies, enclosures, and equipment panels. Manufactured from steel with a zinc finish, this screw meets ASME B18.6.3 and SAE J82 standards, making it a reliable choice for work requiring dimensional consistency and corrosion resistance. The slotted drive accepts a standard flat-blade screwdriver. At 7/16 inches length under head and a 4-40 thread size, this fastener fits a wide range of small-component and sheet-metal applications common in electrical, HVAC, and general mechanical work.

This machine screw is suited for residential and light commercial applications where 4-40 thread fasteners are specified. Typical uses include securing control panels, junction box covers, instrument housings, and small equipment frames. The pan head profile provides a low-profile bearing surface without a washer requirement. It ships in a package quantity of one lot with a minimum order quantity of 100 pieces, making it appropriate for service shops, contractors, and maintenance operations that need a consistent supply of this fastener size.

Key Features

• 4-40 thread size with 7/16-inch length under head for precise dimensional fitment
• Pan head profile with slotted drive for use with standard flat-blade screwdrivers
• Steel construction with zinc finish for corrosion resistance in indoor applications
• Meets ASME B18.6.3 and SAE J82 fastener standards
• No washer required — designed for direct bearing against mating surface

Compatibility

Designed as a standard 4-40 pan head machine screw for use in any application with a 4-40 tapped hole or threaded insert requiring a slotted pan head fastener per ASME B18.6.3.

Installation Notes

Installation is appropriate for any trade or technician working with 4-40 threaded assemblies. Ensure the mating hole is properly tapped to 4-40 specifications before driving the screw. Use a correctly sized flat-blade screwdriver to avoid cam-out and head damage. Do not overtighten in soft materials or thin sheet metal — hand-snug plus a quarter turn is a common starting point for light-gauge applications.
