Value Collection R40692434 Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION R40692434 is a hex socket cap screw designed for precision fastening in applications where a flush, recessed drive is required. Sized at 3/8-24 UNF thread with a 3/4 inch length under the head and a 5/16 inch hex drive, this fastener is manufactured from 18-8 stainless steel for corrosion resistance in wet, chemical, or outdoor environments. It is installed using a hex key or Allen driver and is suited for mechanical assemblies, HVAC equipment mounting, plumbing fixtures, and general industrial use. Machinists, millwrights, HVAC technicians, and plumbers routinely spec this type of fastener where tool clearance is limited and a clean fastener profile is needed.

This screw is appropriate for light to medium-duty fastening tasks across residential and commercial applications. The fine 3/8-24 UNF thread pitch provides better torque control and vibration resistance compared to coarse-thread equivalents, making it a preferred choice in equipment panels, brackets, and precision mechanical assemblies where secure clamping is critical.

Key Features

• 3/8-24 UNF fine thread for precise torque control and vibration resistance
• 5/16 inch internal hex drive accepts standard hex keys and Allen drivers
• 3/4 inch length under head for reliable clamping depth in typical bracket and panel applications
• 18-8 stainless steel construction resists corrosion in wet and chemically active environments
• Low-profile socket cap head allows installation in recessed or tight-clearance locations

Compatibility

Designed as a standard UNF hex socket cap screw suitable for use in any 3/8-24 threaded bore or tapped hole requiring a 5/16 inch hex drive fastener.

Installation Notes

Installation requires a calibrated hex key or Allen driver in 5/16 inch size. Confirm the receiving threads are clean and free of debris before driving. Avoid cross-threading fine UNF threads by starting the screw by hand. Apply appropriate thread lubricant or anti-seize compound when installing stainless fasteners into stainless threaded components to prevent galling.
