Value Collection 201211PR Button Socket Cap Screw 1/2-13x2

Product Description

The VALUE COLLECTION 201211PR is a button socket cap screw designed for mechanical fastening applications that require a low-profile head and high clamping strength. Built from alloy steel with a black oxide coating, this screw offers corrosion resistance and a clean, finished appearance suitable for exposed or semi-exposed assemblies. The 1/2-13 UNC thread and 2-inch length under the head make it a common choice for medium-duty structural and machine assembly work. Drive engagement is through a 5/16-inch hex socket, and the thread fit is Class 3A for precise, tight tolerances. Hardness is rated at 36-43 HRC, meeting ANSI/ASME B18.3 and ASTM F835 standards.

This screw is used across a wide range of industrial, mechanical, and manufacturing applications where a flush or low-profile fastening point is needed. Typical install scenarios include machine frames, equipment panels, brackets, and fixtures where a standard hex head cap screw would protrude too far. The black oxide finish suits both indoor and moderate-exposure environments. Right-hand thread direction is standard for universal compatibility with off-the-shelf nuts and tapped holes. This fastener is sold individually per package with a minimum order quantity of 50 pieces.

Key Features

• Button head profile reduces protrusion in tight or cosmetically sensitive assemblies
• Alloy steel construction with 36-43 HRC hardness for high-load applications
• Black oxide coating provides mild corrosion resistance and a matte finish
• 5/16-inch hex socket drive for positive torque transfer with standard Allen keys
• Class 3A thread fit for tight tolerances and reliable engagement
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in standard 1/2-13 UNC tapped holes or with 1/2-13 UNC hex nuts. Suitable for general mechanical assembly applications where ANSI/ASME B18.3 button socket cap screws are specified.

Installation Notes

Installation requires a 5/16-inch hex socket driver or Allen key. Power down or de-energize any equipment before fastener work in electrical or mechanical enclosures. Confirm hole thread class and depth before installation to ensure proper engagement. Do not exceed rated hardness limits by substituting this fastener in applications requiring Grade 8 or SAE Class 10.9 hex cap screws without engineering review.
