Value Collection R63061441 Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R63061441 is a flat socket cap screw engineered for fastening applications that require a flush or countersunk head profile. It features an 82-degree flat head with a 7/32-inch hex socket drive, allowing installation with a standard hex key or Allen wrench. The thread size is 3/8-16 UNC, and the overall length is 3 inches. Constructed from 18-8 stainless steel, it offers solid resistance to corrosion in wet, humid, or mildly chemical environments. This fastener is suited for mechanical assemblies, structural connections, and equipment maintenance tasks where a low-profile head is required to sit flush with or below the mating surface.

This flat socket cap screw is used across a wide range of trade and industrial applications, including HVAC equipment panels, plumbing fixture mounting, electrical enclosures, and general mechanical assemblies. The 3/8-16 UNC thread pattern is one of the most common unified coarse thread sizes in inch-system hardware, making it straightforward to source matching nuts, threaded inserts, or tapped holes in standard steel, aluminum, or plastic components. The 18-8 stainless steel construction makes it appropriate for installations exposed to moisture or outdoor conditions.

Key Features

• 82-degree flat head sits flush with or below the surface for a low-profile installation
• 7/32-inch hex socket drive compatible with standard hex keys and Allen wrenches
• 3/8-16 UNC thread for broad compatibility with standard tapped holes and hex nuts
• 18-8 stainless steel construction resists corrosion in wet and humid environments
• Overall length of 3 inches suitable for medium-depth fastening applications

Compatibility

Designed as a standard inch-system flat socket cap screw for use in any application requiring a 3/8-16 UNC thread and an 82-degree countersunk head profile.

Installation Notes

Installation requires a properly countersunk hole matching the 82-degree head angle to achieve a flush seating surface. Use a 7/32-inch hex key and apply consistent torque to avoid stripping the socket. When fastening into aluminum or softer base materials, verify that the tapped hole thread engagement is sufficient for the load. Stainless steel fasteners are susceptible to galling during installation — applying an anti-seize compound to the threads is recommended practice.
