Value Collection C52000675 1/4-20 X 2.5 in Round Head Phillips Screw

Product Description

The VALUE COLLECTION C52000675 is a 1/4-20 x 2.5-inch round head Phillips machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. The 1/4-20 UNC thread designation means 1/4-inch nominal diameter with 20 threads per inch, making this a standard coarse-thread fastener. The 18-8 stainless alloy provides corrosion resistance suitable for general-purpose applications in wet, outdoor, or mildly corrosive environments. Sold in a package of 10. Length is measured under the head at 2.5 inches. These screws are appropriate for mechanical assembly, HVAC panel fastening, electrical enclosure work, and similar trade applications requiring a reliable stainless fastener.

This machine screw is used wherever a 1/4-20 coarse-thread fastener with a round Phillips head is required. Common applications include securing equipment panels, junction box covers, HVAC access doors, and general mechanical assemblies in residential and light commercial settings. The Phillips drive is compatible with standard power drivers and hand screwdrivers. The round head profile sits above the work surface and is suited to through-hole fastening without a countersink. No washer is included or integrated into this fastener.

Installation Notes

Installation requires a No. 2 Phillips bit or screwdriver. Ensure the mating hole is correctly tapped to 1/4-20 UNC before driving to avoid cross-threading. When fastening stainless steel screws into stainless hardware, apply an anti-seize compound to prevent galling. Tighten to the structural requirement of the assembly — do not over-torque, as stainless fasteners are susceptible to thread shear under excessive force.
