Value Collection 94590 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION 94590 is a 1/4-20 UNC flat head Phillips machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. It measures 1-1/4 inches in overall length, with the full length measured under the head. The flat head profile sits flush with or below the mating surface when fully driven, making it a common choice where a smooth, low-profile fastener face is required. The Phillips drive accepts standard #2 Phillips bits. Grade 18-8 stainless steel provides corrosion resistance suitable for general indoor and moderate outdoor applications. This screw ships individually but carries a minimum order quantity of 50 units.

This fastener suits a wide range of light to medium-duty assembly tasks encountered by HVAC technicians, plumbers, electricians, and general maintenance trades. Typical applications include securing panels, brackets, junction box covers, equipment enclosures, and sheet metal components where a flush-mount fastener is specified. The 1/4-20 UNC thread is one of the most commonly specified coarse-thread sizes in North American trade work, and the stainless steel construction holds up in damp mechanical rooms, rooftop units, and similar service environments.

Key Features

• 1/4-20 UNC coarse thread — widely compatible with standard tapped holes and hex nuts
• Flat head profile seats flush with the mating surface for low-profile assemblies
• Phillips drive accepts a standard #2 Phillips screwdriver or bit
• Grade 18-8 stainless steel construction resists corrosion in damp or humid environments
• Bright, uncoated finish — no added plating that could flake or interfere with grounding contacts
• No washer — bare shank for use where a separate washer or countersunk hole is specified

Compatibility

Designed as a standard 1/4-20 UNC flat head Phillips machine screw for use in any tapped or through-hole application calling for this thread size, head style, and drive type in inch-measurement fastener specifications.

Installation Notes

Install using a #2 Phillips screwdriver or a #2 Phillips power bit rated for the torque of the application. De-energize any electrical equipment and relieve system pressure before accessing panels or enclosures fastened with these screws. Do not over-drive — the flat head countersink angle must match the mating material to avoid cracking or stripping. When installing into tapped aluminum or plastic, verify thread engagement depth to prevent pull-out.
