Value Collection 3720MPR Machine Screw 3/8-16 X 1-1/4 in Round Head

Product Description

The VALUE COLLECTION 3720MPR is a round head Phillips drive machine screw intended for general-purpose mechanical assembly. It is manufactured from steel with a zinc finish and follows the ASME B18.6.3 and SAE J82 standards for inch-series machine screws. The 3/8-16 thread size and 1-1/4 inch length under head make it suitable for medium-duty fastening applications in metal, wood, and composite assemblies. No washer is included. This fastener is typically installed by maintenance technicians, millwrights, and trade professionals working on equipment panels, brackets, and enclosures where a low-profile round head is required.

This screw is appropriate for use in residential and light commercial applications where inch-series fasteners are specified. Common install scenarios include HVAC equipment panels, electrical enclosures, pump and motor mounting brackets, and general structural assembly. The Phillips drive is compatible with standard No. 3 Phillips bits and drivers. Sold individually with a minimum order quantity of 10 units.

Installation Notes

Install with a No. 3 Phillips screwdriver or compatible power driver bit. Ensure the mating hole is tapped to 3/8-16 UNC before installation.
