Value Collection 211219P Flat Socket Cap Screw 3/8-16x2 in

Product Description

The VALUE COLLECTION 211219P is a flat socket cap screw designed for flush or countersunk fastening applications in metal fabrication, machinery, and structural assemblies. Sized at 3/8-16 x 2 inches with full threading along the entire length, this screw is driven by a 7/32-inch hex socket and seats at an 82-degree flat angle. It is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces light reflection. Machinists, millwrights, and general contractors install this fastener where a low-profile, flush head is required and where a standard hex head would obstruct clearance.

This flat socket cap screw suits a wide range of industrial and mechanical applications including machine frames, fixture plates, jigs, and equipment panels. The 3/8-16 UNC thread pattern is among the most common inch-series coarse thread sizes, making it compatible with standard tapped holes in steel, aluminum, and cast iron components. The fully threaded shank maximizes thread engagement across short-grip applications. It meets ASME/ANSI B18.3 and ASTM F835 fastener standards, making it appropriate for use in precision and load-bearing assemblies.

Key Features

• 82-degree flat head profile for flush or countersunk seating
• 7/32-inch hex socket drive for standard Allen wrench or hex bit installation
• Fully threaded 3/8-16 UNC shank over 2-inch overall length
• Alloy steel construction for strength in load-bearing fastening
• Black oxide finish for reduced reflectivity and light surface protection
• Meets ASME/ANSI B18.3 and ASTM F835 standards

Compatibility

Designed for use in standard 3/8-16 UNC tapped holes in inch-series mechanical and structural assemblies requiring a countersunk flat head fastener.

Installation Notes

Installation requires a 7/32-inch hex key or Allen-drive bit; ensure the mating countersink is machined to an 82-degree included angle for full head seating. Power down or de-energize any equipment before fastener service on live assemblies. Black oxide finish offers limited corrosion protection and is not a substitute for plated or stainless fasteners in wet or outdoor environments. Follow applicable ASME or facility torque guidelines for 3/8-16 fasteners based on the joint material and preload requirements.
