Value Collection R63003926 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R63003926 is a hex socket cap screw designed for fastening applications that require a clean, recessed drive profile and corrosion resistance. Threaded 3/8-16 UNC with a 1-inch length under head, this fastener is fully threaded from end to bearing face. It is driven with a 5/16-inch hex key. Manufactured from 316 stainless steel, it provides strong resistance to rust, oxidation, and chemical exposure. This screw is suited for mechanical assemblies, equipment fabrication, and maintenance tasks across HVAC, plumbing, electrical, and general industrial applications where a socket-drive fastener is specified.

This fastener is commonly used in equipment enclosures, mounting brackets, pump housings, and structural assemblies where access favors an internal hex drive over a hex head. The 316 stainless steel grade makes it appropriate for wet or corrosive environments, including outdoor installations, coastal locations, chemical handling equipment, and pool or water treatment systems. Trade professionals in HVAC, plumbing, and pool service regularly stock this size for field repairs and equipment assembly.

Key Features

• 3/8-16 UNC thread form for broad compatibility with standard tapped holes and nuts
• Fully threaded body provides maximum thread engagement along the entire 1-inch shank
• 5/16-inch internal hex drive accepts standard Allen keys and hex bit drivers
• 316 stainless steel construction resists corrosion in wet, saline, and chemical environments
• Low-profile socket cap head suits flush or recessed installation layouts

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw for use in any tapped hole or with any nut conforming to 3/8-16 UNC thread standards.

Installation Notes

Install using a 5/16-inch hex key or socket bit driver. Ensure the mating tapped hole or nut is clean and free of debris before driving. Apply appropriate thread lubricant or anti-seize compound when installing stainless steel fasteners into stainless tapped holes to reduce the risk of galling. De-energize and isolate any equipment before accessing fasteners on live assemblies.
