Value Collection 586059PR 5-40x5/16 Flat Head Phillips Screw

Product Description

The VALUE COLLECTION 586059PR is a 5-40 x 5/16 inch flat head Phillips machine screw manufactured from steel with a zinc finish. The flat head profile sits flush with or below the mating surface, making it a standard choice for assemblies where a low-profile fastener is required. It meets ASME B18.6.3 and SAE J82 standards, ensuring dimensional consistency across production runs. The zinc finish provides basic corrosion resistance for general indoor mechanical assemblies. This screw is sold in multiples of 100 and is used by machinists, maintenance technicians, electricians, and assemblers working with light-gauge metal or plastic components.

This fastener is suited for light mechanical assemblies, electrical enclosure work, equipment panels, and general-purpose machine applications where a No. 5-40 thread form is specified. The overall length of 5/16 inch is also the length under head, making it appropriate for thin-stock fastening where thread engagement depth is limited. It installs with a standard Phillips driver and does not require a washer.

Key Features

• 5-40 thread size with 5/16 inch overall length for thin-stock applications
• Flat head profile allows flush or countersunk installation
• Phillips drive for compatibility with standard power and hand drivers
• Steel construction with zinc finish for general corrosion resistance
• Meets ASME B18.6.3 and SAE J82 dimensional standards
• No washer required; washer style is without washer

Compatibility

Designed as a standard inch-series machine screw for general mechanical assemblies requiring a No. 5-40 thread and flat head Phillips drive configuration.

Installation Notes

Install with a Phillips head screwdriver or power driver set to appropriate torque to avoid stripping the head. When used in countersunk applications, ensure the mating material is pre-drilled and countersunk to the correct angle to seat the flat head flush. De-energize any electrical equipment before installing fasteners in or around live enclosures. Follow applicable assembly drawings and torque specifications provided by the equipment manufacturer.
