Value Collection R50000174 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION R50000174 is a 1/4-20 x 1-1/2 inch flat head Phillips drive machine screw designed for general fastening applications in metal, wood, and composite materials. Manufactured from Grade 2 steel with a zinc plating finish, this screw resists corrosion and meets standard dimensional tolerances for UNC (Unified National Coarse) thread systems. The flat head profile sits flush with or below the mating surface, making it a common choice when a clean, recessed finish is required. Sold in a minimum order quantity of 100 pieces, this fastener suits production, maintenance, and repair work across mechanical, HVAC, electrical, and plumbing service trades.

This fastener is appropriate for light-to-medium duty clamping and assembly tasks in residential and commercial settings. The 1/4-20 UNC thread is one of the most widely used coarse-thread standards in North American trade work, compatible with standard 1/4-20 nuts, inserts, and tapped holes. Typical applications include panel mounting, bracket assembly, equipment enclosures, and general mechanical assembly where a flush-mounted fastener is specified. The Phillips drive allows use with standard hand drivers and power tools.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard nuts and tapped holes
• Flat head profile sits flush with the mating surface for a clean finish
• Phillips drive accepts standard hand screwdrivers and power bit drivers
• Grade 2 steel construction provides adequate tensile strength for general fastening duty
• Zinc plating provides corrosion resistance in typical indoor service environments
• Overall and under-head length both measure 1-1/2 inches, indicating full-thread configuration

Compatibility

Designed as a standard 1/4-20 UNC machine screw compatible with any 1/4-20 tapped hole, threaded insert, or hex nut conforming to Unified National Coarse thread standards.

Installation Notes

Installation does not require licensed trade credentials, but proper torque control is recommended to avoid stripping the zinc-plated steel threads or the Phillips drive recess. Use a correctly sized Phillips bit to prevent cam-out. Ensure the mating hole is properly tapped or fitted with a compatible insert before driving. When used in electrical enclosures or panels, verify compliance with applicable NEC requirements for fastener type and material.
