Value Collection 583815PR Machine Screw 3/8-16 X 1/2 in

Product Description

The VALUE COLLECTION 583815PR is a 3/8-16 round head slotted machine screw with a 1/2 inch length under head, manufactured from Grade 2 alloy steel with a zinc finish. This fastener uses Unified National Coarse (UNC) thread form and is designed for general-purpose mechanical assembly where a low-profile rounded head and simple slotted drive are appropriate. The zinc coating provides baseline corrosion resistance in typical indoor or sheltered environments. Sold in minimum order quantities, this screw suits production assembly lines, maintenance shops, and field repair kits where standard inch-series fasteners are commonly specified.

This screw is suited for light- to medium-duty mechanical assemblies in HVAC equipment, electrical enclosures, plumbing fixtures, and general industrial applications where 3/8-16 UNC threading is called out. The round head profile sits flush against flat surfaces without requiring a countersink, making it a practical choice for panel attachment, bracket mounting, and equipment covers in both residential and light commercial trade work. A standard flat-blade screwdriver is all that is required for installation.

Key Features

• 3/8-16 UNC thread for compatibility with standard inch-series tapped holes and nuts
• 1/2 inch length under head for shallow-grip applications
• Round head profile requires no countersink preparation
• Slotted drive accepts standard flat-blade screwdrivers
• Grade 2 alloy steel construction for general-purpose mechanical strength
• Zinc finish provides basic corrosion resistance in typical service environments

Compatibility

Designed as a standard inch-series UNC machine screw for use in any tapped hole or with any nut specified for 3/8-16 thread in general mechanical and trade applications.

Installation Notes

Installation requires only a flat-blade screwdriver sized for a 3/8-inch head slot. Always de-energize or shut down the equipment before fastening or removing hardware on electrical or mechanical assemblies. Do not overtighten alloy steel screws into softer base materials such as aluminum or plastic, as thread stripping can occur. Follow applicable equipment manufacturer torque guidelines where specified in service documentation.
