Value Collection 0407MPF 4-40 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION 0407MPF is a 4-40 unified coarse thread machine screw with a flat head and Phillips drive, manufactured from steel with a zinc finish. It measures 7/16 inches in overall length and is built to ASME B18.6.3 and SAE J82 standards. The flat head countersinks flush with the mating surface, making it suitable for applications where a smooth, low-profile fastener is required. This screw is installed by electricians, HVAC technicians, panel assemblers, and mechanical contractors working with light-gauge metal, electronics enclosures, and equipment panels.

This fastener is suited for light-duty mechanical assembly in residential and commercial applications. Common uses include securing control boards, terminal strips, junction box covers, and equipment panels where a 4-40 thread is specified. The zinc finish provides basic corrosion resistance in dry indoor environments. This item is sold in a minimum order quantity of 100 pieces per order, with a package quantity of 1.

Installation Notes

Install using a Phillips screwdriver or a Phillips bit in a power driver set to an appropriate torque clutch setting to avoid stripping the head. Ensure the mating material is tapped or pre-threaded to 4-40 specifications before driving. De-energize and lock out any equipment before replacing or installing fasteners on live panels or enclosures. Follow applicable NEC or equipment manufacturer guidelines for fastener requirements in electrical assemblies.
