Value Collection 3740MPR Round Head Phillips Machine Screw

Product Description

The VALUE COLLECTION 3740MPR is a round head Phillips drive machine screw designed for general-purpose fastening in metal assemblies. Manufactured from steel with a zinc finish, it offers corrosion resistance suitable for indoor and light-duty industrial applications. The screw features a 3/8-16 unified coarse thread and measures 2-1/2 inches in length under the head, making it appropriate for thicker material stacks where extra thread engagement is needed. Conforms to ASME B18.6.3 and SAE J82 standards. No washer is included or integrated. This fastener is used by machinists, millwrights, electricians, and general maintenance trades across commercial and light industrial settings.

This machine screw is suited for metal-to-metal fastening in equipment panels, electrical enclosures, machine frames, and structural brackets. The round head profile sits above the work surface and is appropriate where a low-profile flat head is not required. The Phillips drive allows for quick installation with standard hand or power tools. Sold individually per package, with a minimum order quantity of 5 units.

Key Features

• 3/8-16 unified coarse thread for secure engagement in standard tapped holes
• 2-1/2 inches length under head for use in thicker material applications
• Round head profile with Phillips drive for fast, tool-compatible installation
• Steel construction with zinc finish for corrosion resistance in indoor environments
• Meets ASME B18.6.3 and SAE J82 fastener standards
• No integrated washer — use with a separate flat or lock washer as required

Compatibility

Designed for use in standard 3/8-16 tapped holes per ASME B18.6.3 specifications, compatible with any application requiring a unified coarse thread machine screw of this diameter and length.

Installation Notes

Installation is performed by qualified machinists, maintenance technicians, or tradespeople using a Phillips screwdriver or bit driver sized for a 3/8 inch drive head. Ensure the receiving hole is properly tapped to 3/8-16 UNC before installation. Do not overtighten, as this can strip threads in softer base materials. Verify fastener length is appropriate for the combined material thickness to avoid bottoming out before full clamping force is achieved.
