Value Collection W98450PS 4-40 X 3/16 Pan Head Phillips Screw

Product Description

The VALUE COLLECTION W98450PS is a 4-40 x 3/16 inch pan head machine screw with a Phillips drive, manufactured from 18-8 stainless steel. It meets ASME B18.13 standards and is sized for light-duty mechanical assemblies where corrosion resistance and a low-profile head are required. The length measurement is taken under the head, putting the threaded shank at 3/16 inch. The pan head profile distributes clamping load evenly across the mating surface. An internal tooth washer style is integrated into the design. These screws are sold in multiples of 100 and are suited for production, maintenance, and repair work across industrial, electrical, and mechanical applications.

This screw is used in applications requiring a fine 4-40 unified inch thread in stainless steel. Typical installations include small electrical enclosures, instrument panels, electronic assemblies, and light mechanical fixtures where resistance to rust and mild corrosion is a factor. The Phillips drive accepts standard Phillips screwdrivers and bits. The compact 3/16 inch shank length suits thin-panel and shallow-boss installations. Electricians, mechanical assemblers, and maintenance technicians working on control panels and enclosures commonly specify this fastener size.

Key Features

• 4-40 unified fine thread for secure engagement in small tapped holes
• 18-8 stainless steel construction provides corrosion resistance in moderate environments
• Pan head profile with Phillips drive for standard screwdriver or bit compatibility
• Internal tooth washer style integrated into fastener per ASME B18.13
• Length under head measured at 3/16 inch for shallow-depth installations
• Sold in multiples of 100 to support production and maintenance quantity needs

Compatibility

Designed as a standard 4-40 x 3/16 inch pan head machine screw suitable for use in any tapped or pre-threaded 4-40 hole where an ASME B18.13 Phillips pan head fastener in 18-8 stainless steel is specified.

Installation Notes

Install with a Phillips screwdriver or power driver fitted with a PH0 or PH1 bit sized for a number 4 screw. De-energize any electrical equipment before fastening screws inside control panels or enclosures per applicable NEC requirements. Avoid over-torquing small-diameter machine screws, as 4-40 threads are susceptible to stripping in soft or thin base materials. Verify thread engagement depth in the receiving material before final assembly.
