Value Collection MSC-67570929 Machine Screw 4-40 5/16in Pan Phillips

Product Description

The VALUE COLLECTION MSC-67570929 is a 4-40 UNC machine screw designed for precision fastening in light-duty mechanical and electrical assemblies. The pan head profile provides a low-profile, wide-bearing surface suitable for thin materials and panel applications. The Phillips drive allows for easy installation with standard hand and power tools. Constructed from 18-8 stainless steel with a bright, uncoated finish, this screw resists corrosion in moderately demanding environments. At 5/16 inches in length under head, it is well suited to shallow-clearance fastening situations encountered in control panels, enclosures, and equipment housings.

This screw is used in residential and commercial applications where a small-diameter, fine-thread fastener is required. Typical installations include electrical enclosures, HVAC control boards, instrumentation panels, and light mechanical assemblies. The 4-40 thread size is a standard unified coarse thread (UNC) commonly found in OEM equipment requiring secure, repeatable fastening in thin metal or plastic substrates. Sold in a minimum order quantity of 100 pieces per package.

Installation Notes

Install using a Phillips screwdriver or a power driver with appropriate bit to avoid cam-out on the small head. De-energize and lock out any electrical equipment before fastening screws in control panels or enclosures per NFPA 70 (NEC) guidelines. Do not overtighten into plastic substrates, as the fine thread may strip under excessive torque. Verify tapped hole thread size and depth before installation to ensure proper engagement.
