Value Collection 0404EPP 4-40 X 1/4 in Pan Head Phillips Screw

Product Description

The VALUE COLLECTION 0404EPP is a 4-40 x 1/4 inch pan head machine screw designed for secure fastening in light-duty assemblies. Made from steel with a zinc-plated finish, this screw meets ASME B18.13a and SAE J82 standards for dimensional accuracy and material grade (J82). The Phillips drive makes installation straightforward with standard hand or power tools. The pan head profile provides a low-profile, wide-bearing surface suited for thin material applications. Length is measured under the head at 1/4 inch. This screw is sold in a minimum order quantity of 100 units per order, packaged as a single unit quantity.

This screw is used in general mechanical assembly, electronics enclosures, sheet metal work, and light industrial fabrication where a 4-40 thread form is specified. The external tooth washer style provides added locking capability to resist loosening from vibration. Suitable for applications requiring an inch-system fastener conforming to ASME B18.13a standards. Installers, machinists, and assembly technicians working with 4-40 tapped holes will find this screw a direct fit for standard applications.

Compatibility

Designed as a standard inch-system replacement or production fastener for any application requiring a 4-40 threaded pan head machine screw per ASME B18.13a and SAE J82 specifications.

Installation Notes

Installation is performed by machinists, assembly technicians, or qualified maintenance personnel. Ensure the mating tapped hole is clean and free of debris before driving the screw. Use a correctly sized Phillips screwdriver or bit to avoid cam-out and head damage. Do not overtighten, as the small 4-40 thread form is susceptible to stripping in soft materials.
