Value Collection 0407EPP 4-40 Pan Head Phillips Machine Screw

Product Description

The VALUE COLLECTION 0407EPP is a 4-40 pan head machine screw with a Phillips drive, manufactured from steel with a zinc finish. The screw measures 7/16 inches in length under the head and follows the inch system of measurement. It is designed for general-purpose mechanical assembly and fastening applications where a low-profile pan head and corrosion-resistant zinc coating are required. This fastener meets ASME B18.13a and SAE J82 standards and carries a material grade of J82. An external tooth washer style is incorporated into the design. Installation is straightforward and suits machinists, maintenance technicians, and assembly professionals working with standard 4-40 threaded hardware.

This machine screw is suited for light-duty mechanical and electrical enclosure assemblies where small-diameter inch-series fasteners are standard. The 4-40 thread size is common in instrumentation, control panels, small appliance housings, and electronic equipment chassis. The Phillips drive allows use with standard hand or power screwdrivers, and the zinc finish provides basic corrosion protection in indoor or sheltered environments. This SKU is sold in a package quantity of 1 with a minimum order quantity of 100 units.

Installation Notes

Installation requires a Phillips head screwdriver or bit sized for a number 4 screw. Ensure the mating thread or nut is tapped or rated for 4-40 UNC before installation. Do not overtighten, as the small thread diameter is susceptible to stripping in soft materials. Power down any electrical enclosure or equipment before replacing or installing fasteners in live assemblies.
