Value Collection 37884 1/4-20 X 1-1/4 in Flat Head Phillips Screw 50pk

Product Description

The VALUE COLLECTION 37884 is a 1/4-20 x 1-1/4 inch flat head Phillips machine screw designed for general fastening applications in mechanical assemblies, enclosures, and equipment housings. Manufactured from Grade 2 steel with a zinc-plated finish, this screw resists light corrosion and meets standard UNC (Unified National Coarse) thread specifications. The countersunk flat head sits flush with the mating surface when installed into a properly chamfered hole, making it well-suited for applications where a low-profile finish is required. Sold in a package of 50 units, this fastener is a practical stocking item for shops, service vehicles, and maintenance departments.

This screw is appropriate for use in light- to medium-duty metal and plastic assemblies where 1/4-20 UNC threading is specified. Typical applications include mounting panels, securing equipment covers, and general mechanical assembly work. The zinc plating provides a baseline level of corrosion resistance suited for indoor or sheltered environments. The overall length of 1-1/4 inches is measured from tip to the top of the head, and the length under the head is also 1-1/4 inches as specified for flat head geometry.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and nuts
• Flat countersunk head allows flush installation in chamfered surfaces
• Phillips drive for use with common power and hand drivers
• Grade 2 steel construction provides standard tensile strength for general-purpose use
• Zinc-plated finish for light corrosion resistance in indoor environments
• Packaged in quantities of 50 for bench stock and service inventory

Compatibility

Designed as a standard 1/4-20 UNC flat head Phillips machine screw compatible with any application requiring that thread size, head style, and drive type per inch-system fastener standards.

Installation Notes

Installation is performed with a Phillips screwdriver or Phillips-bit driver of the appropriate size. The mating material should have a pre-tapped 1/4-20 UNC hole or a matching nut; the receiving hole for the flat head should be countersunk to the correct angle to achieve a flush seating surface. Avoid over-torquing Grade 2 fasteners, as this grade has lower proof load ratings than Grade 5 or Grade 8 equivalents. Ensure mating threads are clean and free of debris before installation.
