Value Collection W57756PS 1/4-20 X 1/2 in Flat Head Phillips Screw

Product Description

The VALUE COLLECTION W57756PS is a 1/4-20 UNC machine screw with a flat head and Phillips drive, manufactured from Grade 316 stainless steel with a bright, uncoated finish. The 1/4-20 thread designation indicates a 0.25-inch nominal diameter with 20 threads per inch on a unified coarse thread form. Overall length is 0.5 inches, measured from the tip to the top of the head. Grade 316 stainless steel provides enhanced corrosion resistance compared to 304-series alloys, making it suitable for wet, chlorinated, or chemically aggressive environments. This screw is installed by mechanics, plumbers, electricians, and maintenance technicians across residential, commercial, and industrial applications.

This fastener is used where a flush or countersunk fastening point is required. The flat head profile seats into a countersunk hole to sit flush with or below the surface of the mating material. Grade 316 stainless steel is a standard material choice for pool equipment, marine hardware, coastal HVAC enclosures, chemical processing panels, and any service environment where chloride exposure or moisture contact is a concern. Phillips drive is compatible with standard No. 2 Phillips bits and drivers commonly carried by trade professionals.

Key Features

• Grade 316 stainless steel construction for strong chloride and corrosion resistance
• 1/4-20 UNC thread form for compatibility with standard unified coarse threaded inserts and nuts
• Flat head profile designed for countersunk installations requiring a flush surface finish
• Phillips drive accepts standard No. 2 Phillips bits and screwdrivers
• Bright uncoated finish preserves natural stainless steel surface without added plating
• 0.5-inch overall length suitable for light-duty panel, bracket, and enclosure fastening

Compatibility

Designed as a standard 1/4-20 UNC flat head machine screw for use in any application requiring a countersunk fastener with unified coarse threading and Grade 316 stainless steel material.

Installation Notes

Installation requires a properly countersunk or flat-bottomed clearance hole sized for a 1/4-20 fastener. Use a No. 2 Phillips bit to drive the screw; avoid over-torquing, which can strip the Phillips recess or damage the threaded hole. Power down or de-energize any electrical enclosure before fastening panels or covers. Follow applicable NEC or equipment manufacturer guidelines when securing electrical or HVAC hardware.
