Value Collection W57816PS 1/4-20 X 2.5 in Flat Head Phillips Screw

Product Description

The VALUE COLLECTION W57816PS is a 1/4-20 machine screw designed for general fastening applications where corrosion resistance is a priority. Measuring 2.5 inches in overall length, this flat head Phillips drive screw is manufactured from Grade 316 stainless steel with a bright, uncoated finish. The flat head profile sits flush with or below the mating surface when countersunk correctly, making it well suited for assemblies where a low-profile fastener is required. The 1/4-20 UNC thread form is a standard unified coarse thread, compatible with widely available hardware and tapped holes in that specification. Typically installed by maintenance technicians, fabricators, and trade professionals in marine, chemical, or food-service environments where 316 stainless is specified for its elevated resistance to chlorides and corrosive media.

This screw is appropriate for light to medium structural and panel fastening tasks in residential and commercial applications. Grade 316 stainless steel is commonly specified in coastal installations, HVAC equipment enclosures, plumbing fixture mounting, and any environment where standard 18-8 stainless does not provide adequate corrosion protection. The Phillips drive accepts standard Phillips bits and screwdrivers available in any trade kit. This item ships in a minimum order quantity of 10 units.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in harsh or marine environments
• 1/4-20 UNC thread form for compatibility with standard tapped holes and nuts
• 2.5-inch overall length with full-length threading specification
• Flat head profile designed for flush or countersunk installations
• Bright, uncoated finish — no surface treatment to interfere with torque or fit
• Phillips drive for use with standard Phillips bits

Compatibility

Designed as a standard UNC fastener replacement or new-installation screw for any application requiring a 1/4-20 x 2.5-inch flat head Phillips machine screw in Grade 316 stainless steel.

Installation Notes

Installation should be performed by a qualified technician familiar with proper fastener torque practices for stainless steel hardware. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound to the threads before installation to reduce this risk. Ensure the mating hole is correctly tapped to 1/4-20 UNC specification and that countersunk surfaces match the flat head angle before driving. Do not use impact drivers at high torque settings, as this can damage the Phillips drive recess or cause galling on stainless threads.
