Value Collection 94591 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION 94591 is a 1/4-20 x 1-1/2 inch flat head Phillips machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. It features a Unified National Coarse (UNC) thread form and is measured by overall length at 1-1/2 inches. The flat head profile sits flush with or below the mating surface when countersunk, making it well-suited for assemblies where a low-profile fastener is required. This screw is used by mechanical contractors, maintenance technicians, and fabricators working on equipment panels, brackets, and structural assemblies that require corrosion-resistant fastening hardware.

This machine screw is appropriate for general-purpose fastening applications in residential, commercial, and light industrial settings. The 18-8 stainless steel construction provides solid resistance to corrosion and oxidation, making it a practical choice for use in moist or moderately corrosive environments. The Phillips drive allows use with standard hand and power tools. It is sold individually with a minimum order quantity of 50 pieces, consistent with typical fastener procurement for service trucks and shop stock.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and hex nuts
• Flat head profile designed for countersunk applications where a flush surface is needed
• 18-8 stainless steel construction resists corrosion and oxidation
• Phillips drive works with standard screwdrivers and bit drivers
• Bright uncoated finish — no additional plating to chip, peel, or react with mating materials
• Without washer style — straightforward install with no integrated washer to misalign

Compatibility

Designed as a standard 1/4-20 UNC machine screw for use in any application requiring a flat head Phillips fastener in that thread size and 1-1/2 inch overall length.

Installation Notes

A licensed technician or qualified mechanic should confirm the mating hole is properly countersunk to the correct angle before driving a flat head screw to avoid cracking the surrounding material or cross-threading. Disengage power or de-energize equipment before accessing fastened panels or covers. Use a correctly sized Phillips bit to reduce cam-out and prevent drive recess damage. Stainless fasteners can gall under high torque — use appropriate anti-seize compound when the application demands repeated removal.
