Value Collection R40692408 Hex Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION R40692408 is a hex socket cap screw designed for secure, flush-head fastening in applications where a standard hex bolt head would interfere with surrounding components. Featuring a 3/8-24 UNF thread form, this fastener provides fine-thread engagement suited to applications requiring precise clamping force and vibration resistance. The 5/16-inch hex drive accepts standard Allen keys and hex bit drivers. Constructed from 18-8 stainless steel, the screw offers corrosion resistance in wet or mildly corrosive environments. It is commonly installed by HVAC technicians, plumbers, electricians, and mechanical contractors during equipment assembly, panel mounting, and component fastening tasks.

This cap screw is well suited for light to medium-duty mechanical assemblies in both residential and commercial settings. The fine 3/8-24 UNF thread pitch makes it appropriate for use in tapped metal components where thread stripping risk must be minimized or where fine adjustment is needed. The 18-8 stainless steel construction holds up in damp mechanical rooms, outdoor enclosures, and equipment exposed to moisture. Typical install scenarios include securing control panels, mounting brackets, and equipment covers where a recessed drive head is preferred for clearance or aesthetic reasons.

Key Features

• 3/8-24 UNF fine thread for precise engagement and vibration resistance
• 5/16-inch hex socket drive compatible with standard Allen keys and hex bit sets
• 18-8 stainless steel construction provides corrosion resistance in wet or damp environments
• Low-profile socket cap head allows installation in tight clearance areas
• 1/2-inch length under head suits shallow mounting depths in sheet metal and machined components

Compatibility

Designed as a standard UNF hex socket cap screw for use in any tapped 3/8-24 threaded hole in metal components, brackets, or mechanical assemblies requiring a recessed hex drive fastener.

Installation Notes

Installation requires a 5/16-inch hex key or Allen-style bit driver. Ensure the receiving threads are clean and properly tapped to 3/8-24 UNF specification before driving the screw. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when threading into stainless or aluminum tapped holes. Always de-energize equipment and follow relevant NEC or equipment manufacturer lockout procedures before fastening or removing hardware on electrical or mechanical assemblies.
