Value Collection R52001029 Machine Screw 1/4-20 X 3/8 in

Product Description

The VALUE COLLECTION R52001029 is a 1/4-20 machine screw measuring 3/8 inches in length under head, featuring a round head with combination slotted and Phillips drive. Constructed from steel with a zinc-plated finish, this fastener meets ASME B18.6.3 and SAE J82 standards, making it a reliable choice for general mechanical assembly work. The zinc coating provides basic corrosion resistance in light-duty service environments. Maintenance technicians, millwrights, and trade professionals use this type of screw when securing panels, brackets, enclosures, and equipment covers where a round-head profile is required.

This screw suits a wide range of industrial, commercial, and light mechanical assembly applications. The 1/4-20 unified coarse thread engages standard tapped holes and threaded inserts commonly found in electrical enclosures, HVAC equipment frames, plumbing fixtures, and general structural assemblies. The combination slotted and Phillips drive accommodates both flathead and Phillips screwdrivers, adding flexibility on the job. Sold as a single package with a minimum order quantity of 100 pieces, this fastener is intended for professional use where consistent, standards-compliant hardware is required.

Key Features

• 1/4-20 unified coarse thread for broad compatibility with standard tapped holes and threaded inserts
• 3/8-inch length measured under head for precise fitment in shallow-clearance assemblies
• Round head profile provides a low-profile, finished appearance on exposed fastener locations
• Combination slotted and Phillips drive accepts both flathead and Phillips screwdrivers
• Steel construction with zinc-plated finish for basic corrosion resistance in light-duty service
• Meets ASME B18.6.3 and SAE J82 standards for dimensional and mechanical consistency

Compatibility

Designed for use in standard 1/4-20 tapped holes per inch system fastener applications across general mechanical, electrical, and HVAC assembly work.

Installation Notes

Installation is performed by hand or with a flathead or Phillips screwdriver of appropriate size. Ensure the mating tapped hole or nut is clean and free of debris before driving the screw. Do not overtighten, as this can strip the threads or distort the round head. Follow all applicable equipment manufacturer torque guidelines and relevant installation codes for the system being serviced.
