Value Collection 0403EPP 4-40 Pan Head Phillips Machine Screw

Product Description

The VALUE COLLECTION 0403EPP is a 4-40 pan head machine screw with a Phillips drive, manufactured from steel with a zinc finish. Designed for secure fastening in light-duty mechanical and electrical assemblies, this screw measures 3/16 inches in length under the head and conforms to ASME B18.13a and SAE J82 standards. The pan head profile provides a low-profile bearing surface suited for thin-panel and sheet-metal applications. The zinc coating delivers corrosion resistance suitable for indoor and general-use environments. This fastener is installed by machinists, electricians, HVAC technicians, and field service professionals working on equipment enclosures, control panels, and small mechanical assemblies.

The 0403EPP screw is used in residential and commercial applications wherever a 4-40 threaded fastener is required. Typical installations include control board mounting, terminal block fastening, equipment cover attachment, and general light-duty assembly work. This screw is sold in lots of 100, making it practical for bench stock, service vans, and production assembly operations. The external tooth washer style provides added locking performance in vibration-prone assemblies.

Installation Notes

Installation requires a matching 4-40 tapped hole or nut. De-energize any electrical equipment before fastening control boards or panel components. Use a correctly sized Phillips driver to avoid cam-out and head damage. Follow applicable equipment manufacturer torque guidelines and applicable NEC or equipment-specific code requirements when fastening within electrical enclosures.
