Value Collection 211011PR Flat Socket Cap Screw 2-56

Product Description

The VALUE COLLECTION 211011PR is a flat socket cap screw designed for precision fastening applications requiring a flush or countersunk head profile. Sized at 2-56 UNC thread with an overall length of 3/8 inches, this screw is fully threaded and driven by a hex socket. Constructed from alloy steel with a black oxide finish, it offers solid mechanical strength with moderate corrosion resistance in protected environments. The 82-degree flat head angle conforms to ASME/ANSI B18.3 and ASTM F835 standards, making it a reliable choice for applications where dimensional compliance matters.

This screw is suited for light-duty mechanical assemblies, electronic enclosures, instrumentation panels, and precision equipment where a low-profile or flush-mount fastener is required. The fine 2-56 thread size is common in small-scale machine work, PCB mounting hardware, and tight-tolerance assemblies found in HVAC controls, electrical panel components, and similar trade applications. Installation requires a properly sized hex socket driver to avoid cam-out on the small drive recess.

Key Features

• 82-degree flat head seats flush in standard countersunk holes per ASME/ANSI B18.3
• Fully threaded along the entire 3/8 inch length for maximum thread engagement
• Alloy steel construction provides high tensile strength relative to screw size
• Black oxide finish reduces light reflection and provides mild corrosion protection in dry environments
• Hex socket drive minimizes cam-out risk during installation in tight spaces
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard inch-series flat socket cap screw compatible with any countersunk hole machined to accept a 2-56 UNC thread and an 82-degree flat head profile per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a correctly sized hex key or socket driver matched to the 2-56 drive recess. Always de-energize and lock out equipment before fastening or removing hardware inside electrical or control enclosures. Do not over-torque small-diameter alloy screws, as thread stripping can occur in softer base materials. Countersunk holes should be machined or formed to the correct 82-degree angle to ensure full head seating.
