Value Collection R83920446 Machine Screw 3/8-16 X 1-3/4 in

Product Description

The VALUE COLLECTION R83920446 is a 3/8-16 UNC round head slotted machine screw designed for use in mechanical assemblies, equipment fabrication, and structural fastening applications. Constructed from Grade 18-8 stainless steel with a bright, uncoated finish, this fastener delivers reliable corrosion resistance in environments where mild chemical exposure or moisture is a concern. The screw measures 1-3/4 inches in length under head and carries a 3/8-16 thread form, making it a standard inch-system fastener suitable for a wide range of industrial and trade applications. Installation is straightforward with any standard slotted screwdriver or flat-blade bit.

This fastener is appropriate for residential and light commercial mechanical work, including HVAC equipment panels, plumbing fixture mounting, electrical enclosure assembly, and general equipment maintenance. The round head profile provides a low-profile bearing surface without requiring a countersunk or recessed hole, making it well suited for through-hole applications in sheet metal, plastics, and light structural members. Technicians working in corrosive or wet service environments frequently specify 18-8 stainless fasteners as a direct replacement for carbon steel screws prone to rust and seizing.

Key Features

• Grade 18-8 stainless steel construction provides corrosion resistance in wet and mildly corrosive environments
• 3/8-16 UNC thread form is a standard inch-system coarse thread for broad compatibility
• Round head style suits through-hole installations without countersinking
• Slotted drive accepts standard flat-blade screwdrivers and bits
• Bright, uncoated finish with no added plating that could compromise thread tolerances
• Sold without washer — fastener length measured from under the head at 1-3/4 inches

Compatibility

Designed as a standard 3/8-16 UNC inch-system machine screw suitable for use in any application requiring a round head slotted fastener of this thread size and length. Verify mating thread, material, and load requirements before installation.

Installation Notes

This fastener is installed by maintenance technicians, HVAC service pros, electricians, and plumbers during equipment assembly or field repair. Always verify that the mating threaded hole or nut matches the 3/8-16 UNC thread specification before driving the screw. Apply appropriate torque using a calibrated torque wrench or driver when fastener joint integrity is critical to equipment safety. De-energize electrical equipment and shut off fluid systems before accessing any panel or enclosure requiring fastener replacement.
