Value Collection 583867PS 3/8-16 Round Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 583867PS is a 3/8-16 UNC machine screw with a round head and slotted drive, manufactured from alloy steel with a zinc finish. Measuring 2-1/4 inches in length under head, this fastener is sized for applications requiring a full-grip bearing surface under the head without a washer face. The zinc coating provides basic corrosion resistance suitable for indoor and general mechanical assemblies. Machinists, millwrights, maintenance technicians, and general tradespeople install this screw type when assembling equipment panels, brackets, fixtures, and machine components where a slotted drive is specified or preferred.

This screw is suited for general-purpose mechanical assembly in both light industrial and commercial maintenance environments. The 3/8-16 UNC thread is one of the most widely used coarse-thread inch-series sizes, making it a common replacement or build-out fastener across a broad range of equipment. Typical applications include panel mounting, structural bracket assembly, and equipment fabrication where alloy steel strength and a standard inch thread form are required. Sold individually as a single piece with a minimum order quantity of 50 units.

Key Features

• 3/8-16 UNC coarse thread for broad inch-series compatibility
• 2-1/4 inch length measured under the head for accurate fit in threaded assemblies
• Round head profile provides a wide, low-profile bearing surface
• Slotted drive accommodates standard flat-blade screwdrivers and bits
• Alloy steel construction for strength in mechanical fastening applications
• Zinc finish provides basic corrosion resistance for general indoor use

Compatibility

Designed as a general-purpose inch-series machine screw compatible with any standard 3/8-16 UNC tapped hole or threaded nut in mechanical assemblies requiring a round head slotted fastener without a washer face.

Installation Notes

Install using a flat-blade screwdriver or slotted bit of appropriate width to avoid cam-out and slot damage. Ensure the mating tapped hole or nut is clean and thread-chased before installation. Apply appropriate thread lubricant or thread-locking compound per the assembly specification. De-energize and lock out any equipment before accessing fastener locations in live electrical or mechanical systems.
