Value Collection R52001178 3/8-16 X 2 in Flat Head Phillips Screw

Product Description

The VALUE COLLECTION R52001178 is a 3/8-16 flat head Phillips machine screw designed for general-purpose mechanical fastening in metal and metal-to-metal assemblies. Manufactured from steel with a zinc plating finish, it meets ASME B18.6.3 and SAE J82 standards for dimensional accuracy and material grade. The flat head profile sits flush with or below the mating surface when countersunk, making it suited for applications where a low-profile fastener is required. At 2 inches in overall length with a 3/8-16 UNC thread, this screw covers a wide range of medium-duty fastening tasks encountered in equipment assembly, machine maintenance, and structural panel work.

This screw is appropriate for use in light to medium industrial assemblies, machinery enclosures, equipment frames, and structural components where a flush-mount fastener is needed. The Phillips drive is compatible with standard Phillips screwdrivers and power drive bits, making installation straightforward on the bench or in the field. Trades including millwrights, maintenance technicians, and electricians commonly use this size and style when assembling panel enclosures, mounting hardware, or fabricating support structures.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes and hex nuts
• Flat head profile allows flush or countersunk installation in mating surfaces
• Phillips drive accepts standard No. 3 Phillips bits for hand or power installation
• Zinc plating provides corrosion resistance in indoor and light-duty environments
• Meets ASME B18.6.3 and SAE J82 for dimensional and material grade compliance
• Steel construction rated to Grade J82 for consistent tensile performance

Compatibility

Designed as a standard 3/8-16 UNC flat head Phillips machine screw for use in any application requiring ASME B18.6.3 compliant fasteners of this thread size and length.

Installation Notes

Installation should be performed by a qualified technician or tradesperson familiar with fastener torque practices for the mating material. Ensure the receiving hole is properly tapped or fitted with a compatible nut before driving. Use a correctly sized No. 3 Phillips driver or bit to avoid cam-out and head damage. For countersunk installations, verify the countersink angle and depth match the flat head geometry before final assembly.
