Value Collection 586793PR Machine Screw 3/8-16 X 3-1/2

Product Description

The VALUE COLLECTION 586793PR is a 3/8-16 flat head Phillips drive machine screw designed for general mechanical assembly and fastening applications. It measures 3-1/2 inches in overall length and carries a 3/8-16 unified coarse thread form. The screw is manufactured from steel with a zinc finish that provides basic corrosion resistance in dry indoor environments. The flat head profile sits flush with the mating surface when installed in a countersunk hole, making it well suited for assemblies where a low-profile fastener is required. Licensed trades and maintenance technicians across HVAC, electrical, and general mechanical work regularly use this fastener type for panel mounting, equipment enclosures, and structural bracketing tasks.

This screw is used in light to medium-duty mechanical assembly wherever a 3/8-16 coarse thread fastener is called for. Typical applications include equipment mounting, junction box fabrication, structural steel framing connections, and general MRO maintenance tasks. It installs with a standard Phillips screwdriver or a Phillips bit in a power driver. The without-washer style and flat head geometry suit countersunk clearance holes in steel, aluminum, or composite panels.

Key Features

• 3/8-16 unified coarse thread for broad compatibility with standard nuts and tapped holes
• Flat head with Phillips drive for flush-mount installation in countersunk applications
• Steel construction with zinc finish for basic corrosion resistance
• Material grade J82 per ASME B18.6.3 and SAE J82 standards
• Overall length of 3-1/2 inches equals length under head measurement
• Without washer style for clean countersink seating

Compatibility

Designed as a standard 3/8-16 coarse thread machine screw suitable for use with any 3/8-16 threaded nut, insert, or tapped hole conforming to ASME B18.6.3 dimensional standards.

Installation Notes

Install using a properly sized Phillips screwdriver or Phillips-tipped power driver to avoid cam-out and fastener damage. Prepare the receiving material with a correctly sized countersink to achieve a flush seating surface before driving. Ensure the mating nut or tapped hole is clean and free of debris before assembly. Apply appropriate torque for the grade and material; do not exceed the fastener's rated capacity in shear or tension applications.
