Value Collection 0408IPP 4-40 X 1/2 in Pan Head Phillips Screw

Product Description

The VALUE COLLECTION 0408IPP is a 4-40 pan head machine screw designed for precision fastening in light mechanical assemblies. It features a Phillips drive and measures 1/2 inch in length under the head. Manufactured from steel with a zinc finish, this screw conforms to ASME B18.13a and SAE J82 standards, making it suitable for applications where dimensional consistency and corrosion resistance are required. The internal tooth washer style provides added resistance to loosening under vibration. Sold in multiples of 100, this screw is a standard choice for technicians and assemblers working with small-frame components across HVAC, electrical, and general mechanical equipment.

This screw is used in residential and commercial equipment assembly and service work where 4-40 threaded fasteners are specified. Common applications include control board mounting, panel hardware, small enclosure assembly, and light-duty mechanical assemblies. The pan head profile provides a low-profile bearing surface suitable for thin materials and close-tolerance installations. The Phillips drive is compatible with standard power and manual screwdrivers, making installation straightforward in the field or on the bench.

Installation Notes

Installation is performed by technicians and assemblers using standard Phillips screwdrivers or compatible power drivers. Always power down and de-energize equipment before servicing panels or control boards where these screws are used. Do not overtighten into thin sheet metal or plastic standoffs, as thread stripping can occur. Follow equipment manufacturer torque guidance where specified in service documentation.
