Value Collection 586787PS 3/8-16 X 1-1/2 Flat Head Phillips Screw

Product Description

The VALUE COLLECTION 586787PS is a 3/8-16 flat head Phillips drive machine screw designed for general mechanical assembly and structural fastening applications. Manufactured from steel with a zinc finish, this screw meets ASME B18.6.3 and SAE J82 dimensional and material grade standards. The flat head profile sits flush with or below the mating surface when installed in a countersunk hole, making it well-suited for assemblies where a low-profile or flush fastener is required. The 3/8-16 thread is a coarse-pitch Unified National thread, providing strong engagement in steel, aluminum, and other common structural materials. Licensed trades and general contractors regularly use fasteners of this type in equipment mounting, panel assembly, and machinery repair.

This screw is appropriate for residential and commercial mechanical, electrical, and structural assembly work where a flush-mount fastener is needed. The 1-1/2 inch overall length and 3/8-16 thread size suit medium-duty clamping applications in steel fabrication, equipment frames, enclosures, and general industrial maintenance. No washer is included or required under the head for standard countersunk installations. The zinc finish provides baseline corrosion resistance for interior and protected exterior environments.

Key Features

• Flat head profile seats flush in countersunk holes for low-profile assemblies
• Phillips drive compatible with standard and impact Phillips bits
• 3/8-16 coarse-thread pitch for strong engagement in most structural materials
• Steel construction with zinc finish for corrosion resistance in protected environments
• Meets ASME B18.6.3 and SAE J82 standards for dimensional accuracy and material grade
• Overall length of 1-1/2 inches with full-length thread under the head

Compatibility

Designed as an OEM-style replacement or general-use fastener compatible with any application requiring a 3/8-16 coarse-thread flat head Phillips machine screw with a 1-1/2 inch overall length.

Installation Notes

Installation requires a properly sized countersunk hole to seat the flat head flush. Use a Phillips bit sized for a 3/8 fastener and apply appropriate torque for the mating material to avoid stripping the drive or over-stressing the thread. Always de-energize and lock out equipment before replacing or installing fasteners in electrical enclosures or powered machinery. Follow applicable codes such as the NEC or relevant ASME standards for fastener selection in code-governed assemblies.
