Value Collection 0508MPR 5-40 X 1/2 in Round Head Phillips Screw

Product Description

The VALUE COLLECTION 0508MPR is a 5-40 x 1/2 inch round head Phillips machine screw manufactured from steel with a zinc finish. This fastener features a #5-40 unified coarse thread, a round head profile, and a Phillips drive recess for use with standard Phillips drivers or bits. It is sized by length under head at 1/2 inch and meets ASME B18.6.3 and SAE J82 dimensional and performance standards. Grade J82 designates it for general-purpose mechanical assembly applications. Sold in a minimum order quantity of 100 pieces, this screw is a staple in precision panel assembly, equipment enclosures, and light-duty mechanical fastening across industrial and trade settings.

This screw is suited for use in residential and commercial equipment assembly, electrical enclosures, control panels, HVAC unit casings, and other light mechanical assemblies requiring a small-diameter threaded fastener. The #5-40 thread size is common in instrumentation, control boards, and sheet-metal work throughout the HVAC, electrical, and mechanical trades. The zinc finish provides basic corrosion resistance for indoor and protected outdoor environments.

Key Features

• Thread size #5-40 unified coarse thread for reliable engagement in tapped holes and nuts
• 1/2 inch length under head for precise depth control in light-gauge assemblies
• Round head profile distributes clamping load across a wider surface area
• Phillips drive compatible with standard Phillips No. 1 or No. 2 drivers and bits
• Zinc finish provides corrosion resistance for general indoor use
• Meets ASME B18.6.3 and SAE J82 standards for dimensional accuracy and material grade

Compatibility

Designed for use in any application requiring a #5-40 threaded machine screw with a round head Phillips drive, including control panel assembly, electrical enclosures, HVAC equipment casings, and general mechanical fastening in inch-system assemblies without a washer face.

Installation Notes

Install using a Phillips No. 1 or No. 2 screwdriver or power driver bit appropriate for the head size. De-energize and lock out all electrical equipment before fastening or removing screws on control panels or energized enclosures per NFPA 70E safe work practices. Do not overtighten in tapped plastic or soft-metal holes, as the fine thread engagement on small-diameter screws can strip under excess torque. Confirm thread engagement depth is sufficient for the application before final assembly.
