Value Collection R83924924 5/16-18 X 2 in Round Head Screw

Product Description

The VALUE COLLECTION R83924924 is a 5/16-18 x 2 inch stainless steel machine screw with a round head and slotted drive. Built from 18-8 stainless steel with a bright, uncoated finish, this fastener is suited for general mechanical assembly where corrosion resistance and a clean appearance matter. The 5/16-18 thread designation indicates a 5/16 inch nominal diameter with 18 threads per inch in the Unified National Coarse (UNC) series. Length is measured under the head at 2 inches. No washer is included or integrated. This screw is used by HVAC technicians, plumbers, electricians, and general maintenance professionals in a wide range of equipment assembly and panel-mounting applications.

This fastener is appropriate for light to medium-duty mechanical connections in both residential and commercial service environments. It is commonly used in equipment panels, junction boxes, access covers, and structural hardware where stainless steel is preferred over zinc-plated carbon steel for longevity in humid or corrosive conditions. The slotted drive is compatible with standard flat-blade screwdrivers and is a common configuration in legacy and current equipment. Sold individually, with a minimum order quantity of 5 units.

Key Features

• 5/16-18 UNC thread — widely compatible with standard tapped holes in trade equipment
• 2 inch length under head for adequate engagement in typical panel and bracket assemblies
• 18-8 stainless steel construction offers corrosion resistance in humid and wet service environments
• Round head profile provides a low-profile bearing surface without a washer
• Slotted drive accepts standard flat-blade screwdrivers — no specialty tooling required
• Bright, uncoated finish — no added plating that can flake or interfere with electrical bonding

Compatibility

Designed as a standard 5/16-18 UNC machine screw suitable for any application requiring a round head slotted fastener in this thread size and length.

Installation Notes

Install using a flat-blade screwdriver sized to fit the slotted head fully to avoid cam-out and fastener damage. De-energize any electrical equipment and shut off fluid systems before replacing or installing fasteners in live assemblies. Do not overtighten stainless steel fasteners, as 18-8 alloy is susceptible to galling when torqued without lubrication — apply an anti-seize compound to the threads when the application allows. Follow applicable equipment manufacturer torque guidelines and relevant codes such as the NEC or IPC where fasteners are used in regulated assemblies.
