Value Collection W57540PS 10-24x1 Flat Phillips 316 Ss Screw

Product Description

The VALUE COLLECTION W57540PS is a 10-24 x 1 inch overall length flat head Phillips drive machine screw 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, making it well suited for applications where a smooth surface is required. Unified National Coarse (UNC) threading runs the full length of the shank. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, particularly in chloride-rich or marine environments. These fasteners are sold in multiples of 25.

This machine screw is appropriate for light mechanical assemblies, electrical enclosures, HVAC equipment panels, plumbing fixtures, and general industrial maintenance work. The Phillips drive is compatible with standard bit drivers and is widely used in production and service environments. The 10-24 UNC thread size is a common standard in trade applications and pairs with a corresponding 10-24 nut or threaded insert. The bright, uncoated finish leaves the base alloy exposed, which is acceptable where the inherent corrosion resistance of Grade 316 stainless is sufficient.

Key Features

• Grade 316 stainless steel construction for strong corrosion resistance in wet or marine-adjacent environments
• 10-24 UNC thread form, a widely standardized size in trade and light industrial fastener applications
• Flat head profile designed for countersunk holes to achieve a flush or sub-flush surface finish
• Phillips drive compatible with standard No. 2 Phillips bits and power drivers
• Bright, uncoated finish — no plating or coating that could introduce contamination or measurement variance
• 1 inch overall length equals 1 inch length under head on this flat head configuration

Compatibility

Designed for use in any application requiring a 10-24 UNC flat head Phillips machine screw in Grade 316 stainless steel. Suitable for countersunk holes conforming to standard 82-degree flat head dimensions per ASME B18.6.3.

Installation Notes

Installation is performed with a No. 2 Phillips bit driver, either manual or powered. The mating hole should be countersunk to the appropriate 82-degree angle to seat the flat head flush. Avoid over-torquing stainless steel fasteners, as the alloy is susceptible to galling — apply an anti-seize compound when threading into stainless or aluminum tapped holes. Ensure the mating threaded hole or nut matches the 10-24 UNC specification before driving.
