Value Collection 0504MPR 5-40 X 1/4 in Round Head Phillips Screw

Product Description

The VALUE COLLECTION 0504MPR is a 5-40 unified coarse thread machine screw designed for light-duty fastening applications in metal assemblies. The round head profile and Phillips drive make it compatible with standard screwdrivers and power drivers. Manufactured from steel with a zinc finish, the screw delivers corrosion resistance suitable for indoor mechanical and electrical enclosure work. At 1/4 inch length under head, this fastener fits compact panel and chassis applications. Conforming to ASME B18.6.3 and SAE J82 standards, it meets dimensional and mechanical requirements expected in professional trade and light industrial use. Sold in a minimum order quantity of 100 pieces per package.

This screw is commonly used in HVAC control panel assemblies, electrical enclosures, switchgear, and light-gauge sheet metal applications where a No. 5-40 thread is specified. The round head sits flush above the material surface, making it a practical choice where a low-profile dome head is preferred over a flat or pan head. Installation is straightforward and does not require tapping beyond a pre-threaded hole or a clearance hole paired with a nut. Trade professionals including electricians and HVAC technicians will find this size appropriate for securing light components and small brackets within equipment cabinets.

Installation Notes

Installation should be performed by a qualified technician following applicable codes such as the NEC for electrical enclosure work. Power down all equipment and de-energize panels before fastening or removing hardware inside control cabinets. Use a properly sized Phillips driver to avoid cam-out and head damage. Do not over-torque into thin sheet metal or thermoplastic standoffs, as the fine thread engagement on light-gauge material is limited.
