Value Collection 0410MPR 4-40 X 5/8 in Round Head Phillips Screw

Product Description

The VALUE COLLECTION 0410MPR is a 4-40 unified coarse thread machine screw designed for precision fastening applications in light-gauge metal, electronics, and equipment assembly. The round head profile provides a low-profile dome shape suitable for through-hole and clearance-hole installations. Driven by a Phillips bit, the screw measures 5/8 inches in length under head. It is manufactured from steel with a zinc-plated finish that provides corrosion resistance in indoor and light-duty environments. Conforming to ASME B18.6.3 and SAE J82 standards, this fastener is sold in minimum order quantities of 100 pieces per transaction.

This screw is used across a wide range of trade and light industrial applications including HVAC control panel assembly, electrical enclosure fabrication, small appliance repair, and electronic equipment maintenance. The 4-40 thread size is common in instrument panels, junction boxes, and low-voltage control boards where compact fasteners are required. Technicians and assemblers working with sheet metal chassis or plastic housings will find this a standard replacement or assembly fastener for #4 tapped holes.

Key Features

• 4-40 unified coarse thread for reliable engagement in standard #4 tapped holes
• Round head profile with Phillips drive for easy installation with a standard bit
• 5/8-inch length under head suits moderate material stack thicknesses
• Zinc-plated steel construction provides indoor corrosion resistance
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards
• No washer — clean underhead bearing surface for direct contact fastening

Compatibility

Designed as a standard 4-40 machine screw for any application requiring a #4-40 unified coarse thread fastener with a round Phillips head per ASME B18.6.3 specifications.

Installation Notes

Install using a Phillips screwdriver or a No. 1 Phillips bit in a power driver set to a low torque clutch setting to avoid stripping the small-diameter thread. Ensure the mating tapped hole is clean and free of debris before driving. Do not overtighten — 4-40 threads are fine-pitch and the screw cross-section is small, making them susceptible to shear under excessive torque. For electrical panel applications, follow applicable NEC guidelines for fastener use in enclosures.
