Value Collection R40682409 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R40682409 is a hex socket cap screw designed for secure mechanical fastening in a wide range of industrial and trade applications. Threaded at 3/8-16 UNC, this screw features a 5/16 inch hex drive socket and a 1/2 inch length under head. The cap head design allows flush or recessed installation using a standard hex key or Allen driver. Constructed from 18-8 stainless steel, it resists corrosion in both wet and dry environments. Weighing 0.034 pounds per unit, it is suited for applications where weight and material integrity are both considerations.

This screw is a standard fastener for mechanical assemblies, equipment mounting, and structural connections across HVAC, plumbing, electrical, and general industrial work. The 3/8-16 UNC thread pattern is a common coarse-thread specification found in a broad range of equipment frames, brackets, and enclosures. The 18-8 stainless steel grade makes it appropriate for interior and exterior installations where moisture or chemical exposure is a factor. It is typically installed by maintenance technicians, millwrights, and trade professionals during equipment assembly or field repair work.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• 5/16 inch hex socket drive for use with standard Allen keys or hex bit drivers
• 1/2 inch length under head for controlled fastening depth in typical bracket and panel applications
• 18-8 stainless steel construction provides corrosion resistance in wet and chemically exposed environments
• Cap head profile allows countersunk or flush-mount installation in machined or drilled surfaces

Compatibility

Designed as a standard UNC coarse-thread fastener suitable for use in any application requiring a 3/8-16 threaded socket cap screw in stainless steel.

Installation Notes

Install using a properly sized 5/16 inch hex key or Allen bit driver. De-energize and lock out all equipment before fastener work on live assemblies. Do not overtighten stainless steel fasteners, as galling can occur without proper lubrication or anti-seize compound on the threads. Fastener installations on structural or pressure-bearing assemblies should follow applicable equipment manufacturer torque guidance and relevant code requirements.
