Value Collection 0416MPR 4-40 X 1 in Round Head Phillips Screw

Product Description

The VALUE COLLECTION 0416MPR is a 4-40 x 1 inch round head Phillips machine screw designed for precision fastening in light-duty mechanical and electronic assemblies. Manufactured from steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J82 standards for dimensional and material consistency. The round head profile provides a low-profile bearing surface suitable for thin panels and enclosures. Length is measured under the head. This screw is sold in a minimum order quantity of 100 pieces per order, making it practical for shop stock and repeat service calls.

This fastener is used across a wide range of applications including electrical panel assemblies, HVAC control boards, light-gauge sheet metal enclosures, and small equipment housing. The 4-40 thread size is common in instrument panels, terminal boxes, and electronic component mounting. It is installed by electricians, HVAC technicians, and equipment assemblers wherever a small-diameter, corrosion-resistant machine screw with a Phillips drive is required.

Key Features

• 4-40 thread size x 1 inch length under head for precise fit in standard tapped holes
• Round head Phillips drive for easy installation with common hand and power tools
• Steel construction with zinc-plated finish for corrosion resistance in indoor environments
• Meets ASME B18.6.3 and SAE J82 dimensional and material grade standards
• No washer included; designed for use without a washer where clean seating is needed
• Inch measurement system; compatible with standard imperial tapped hardware

Compatibility

Designed as a standard imperial machine screw for use in any application requiring a 4-40 tapped hole with a round head Phillips fastener per ASME B18.6.3 specifications.

Installation Notes

Install using a Phillips screwdriver or bit sized for a number 4 screw to avoid cam-out and head damage. Ensure the mating hole is properly tapped to 4-40 specifications before installation. Do not overtighten; steel screws in small diameters are susceptible to thread stripping in softer base materials. Follow applicable NEC or equipment manufacturer guidelines when fastening within electrical enclosures.
