The VALUE COLLECTION 3128MPP is a pan head machine screw designed for general-purpose mechanical fastening in metal and non-metal assemblies. Sized at 5/16-18 thread with a 1-3/4 inch length under head, it uses a Phillips drive and is manufactured from steel with a zinc finish. The zinc coating provides basic corrosion resistance for interior and sheltered applications. Conforming to ASME B18.6.3 and SAE J82, this fastener meets standard dimensional and mechanical requirements for inch-series machine screws. It is commonly installed by maintenance technicians, assemblers, and trade professionals across HVAC, electrical, and general mechanical applications.
This screw is suited for use in light to medium-duty fastening tasks where a pan head profile is required to distribute clamping load over a wider surface area. Typical applications include equipment panels, junction boxes, light structural brackets, and similar assemblies that require a 5/16-18 coarse-thread fastener. The Phillips drive is compatible with standard Phillips screwdrivers and power drivers with the appropriate bit size. Sold individually per package with a minimum order quantity of 100 pieces.
Designed as an OEM-style replacement or general-use fastener for assemblies requiring a 5/16-18 x 1-3/4 inch pan head Phillips machine screw with zinc finish and no washer face.
Installation should be performed by qualified technicians or assemblers familiar with proper fastener torque practices for 5/16-18 steel screws. Ensure mating threads are clean and free of debris before installation. Do not exceed appropriate drive torque for the Phillips head, as over-driving can strip the recess. Follow applicable equipment manufacturer guidelines and relevant codes such as NEC or ASME standards when installing fasteners in electrical or mechanical enclosures.
