Value Collection R52001189 Machine Screw 3/8-16 X 4 in

Product Description

The VALUE COLLECTION R52001189 is a flat head Phillips drive machine screw designed for general industrial and mechanical fastening applications. It features a 3/8-16 unified coarse thread and measures 4 inches in overall length. The screw is manufactured from steel to Grade J82 and finished with a zinc plating that provides basic corrosion resistance in standard service environments. It conforms to ASME B18.6.3 and SAE J82 dimensional and performance standards. The flat head profile sits flush with or below the surface of the mating material when countersunk correctly, making it a common choice where a low-profile fastener is required. Sold individually, with a minimum order quantity of 5 units.

This screw is suited for use in light machinery, equipment assemblies, enclosures, and structural fastening tasks where a 3/8-16 coarse-thread fastener is specified. The Phillips drive is compatible with standard power drivers and hand tools, making it practical for production environments and field maintenance work alike. The zinc finish is appropriate for indoor or lightly protected outdoor settings where mild corrosion protection is acceptable.

Key Features

• 3/8-16 unified coarse thread for broad hardware compatibility
• 4-inch overall length with no washer face
• Flat head profile allows flush or countersunk installation
• Phillips drive compatible with standard power and hand drivers
• Zinc-plated steel construction meets ASME B18.6.3 and SAE J82 standards

Compatibility

Designed as a standard 3/8-16 coarse-thread machine screw for use in any application specifying an ASME B18.6.3 flat head Phillips fastener in that thread size and length.

Installation Notes

Install using a properly sized Phillips driver bit to avoid cam-out and fastener head damage. For flush or recessed seating, ensure the receiving material is countersunk to the correct angle before driving. De-energize or lock out any equipment before performing fastener work on live assemblies. Apply thread torque consistent with Grade J82 steel specifications per the applicable mechanical or structural standard for the job.
