Value Collection R83920424 3/8-16 Machine Screw Round Head

Product Description

The VALUE COLLECTION R83920424 is a 3/8-16 UNC machine screw with a round head and slotted drive, manufactured from 18-8 stainless steel with a bright uncoated finish. It measures 1-1/4 inches under the head and is sold individually. The 18-8 stainless steel construction provides solid corrosion resistance in wet, marine, and general industrial environments. This screw is installed by machinists, maintenance mechanics, HVAC technicians, plumbers, and electricians wherever a standard inch-series threaded fastener is required in a corrosion-prone application.

This fastener is suited for general mechanical assembly, equipment maintenance, and panel or bracket fastening in residential and commercial applications. The 3/8-16 UNC thread is one of the most common coarse-thread sizes in inch-standard work, making this screw a practical stock item for service trucks and shop inventory alike. The slotted drive is compatible with standard flat-blade screwdrivers and is commonly found in legacy equipment and fixtures.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• 3/8-16 UNC coarse thread for broad compatibility with standard inch-series tapped holes
• Round head profile provides a low-profile bearing surface without a washer
• Slotted drive works with standard flat-blade screwdrivers and is compatible with legacy hardware
• Bright uncoated finish — no plating to chip, flake, or contaminate threads
• Length under head: 1-1/4 inches for consistent grip-length calculation

Compatibility

Designed as a standard inch-series replacement or stock fastener for equipment, panels, brackets, and assemblies requiring a 3/8-16 UNC round-head slotted machine screw in stainless steel.

Installation Notes

Install with a flat-blade screwdriver sized to the slotted head to avoid cam-out and slot damage. Ensure the mating tapped hole or nut is 3/8-16 UNC thread form before installation. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when threading into stainless or aluminum components. Follow applicable mechanical codes and equipment manufacturer specifications for required torque and fastener count.
