Value Collection R83924438 Slotted Round Head Machine Screw

Product Description

The VALUE COLLECTION R83924438 is a 10-24 UNC machine screw with a round head and slotted drive, manufactured from 18-8 stainless steel with a bright, uncoated finish. The 7/8-inch length is measured under the head. This screw delivers reliable corrosion resistance in demanding applications where moisture, chemicals, or outdoor exposure are factors. It is suitable for general mechanical assembly work performed by millwrights, maintenance technicians, HVAC installers, electricians, and plumbers requiring standard UNC fasteners.

This machine screw is used in light to medium-duty mechanical assemblies across residential and commercial applications. The round head profile provides a low-profile finished appearance and broad bearing surface for through-fastening applications. The slotted drive is compatible with standard flat-blade screwdrivers and power bits. The 18-8 stainless steel composition makes it well suited for environments where mild corrosive exposure is expected, such as equipment panels, junction boxes, HVAC housings, and plumbing fixtures.

Key Features

• 10-24 UNC thread form for compatibility with standard inch-series tapped holes and nuts
• 18-8 stainless steel construction for corrosion resistance in wet or chemical-exposed environments
• Round head profile with broad bearing surface for clean through-fastening applications
• Slotted drive works with standard flat-blade screwdrivers and common power tool bits
• Bright uncoated finish — no surface treatment that could introduce dimensional variation at the thread
• Length measured under head at 7/8 inches for predictable grip-length planning

Compatibility

Designed as a standard inch-series UNC machine screw for use with any 10-24 tapped hole or hex nut in general mechanical, electrical, HVAC, and plumbing assembly applications.

Installation Notes

Install using a flat-blade screwdriver or appropriate slotted power bit. Verify the mating tapped hole or nut is 10-24 UNC before driving. Avoid over-torquing stainless steel fasteners — galling can occur if run in dry at high speed. Apply an anti-seize compound to the threads when fastening into stainless or aluminum to reduce the risk of thread seizure.
