Value Collection 701201PR Button Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION 701201PR is a button socket cap screw designed for mechanical assemblies where a low-profile head and high clamping strength are both required. It features a 1/2-13 UNC thread with a 2-1/2 inch length under the head, a 5/16 inch hex socket drive, and a button-style head that sits closer to the surface than a standard cap screw. Made from alloy steel with a black oxide coating, it delivers hardness in the 36 to 43 HRC range and resists mild corrosion in protected environments. Installation requires a matching hex key or socket driver. This fastener meets ANSI/ASME B18.3 and ASTM F835 standards.

This screw suits general industrial, mechanical, and structural applications where a flush or recessed fastener head is preferred. Common uses include machine frames, brackets, jigs, fixtures, and equipment panels. The black oxide finish provides a clean appearance alongside light surface protection, making it appropriate for indoor or sheltered installations. It is sold individually but carries a minimum order quantity of 5 units, making it practical for both single-point repair and small-batch production work.

Key Features

• Button head profile reduces protrusion and snag risk in tight clearance areas
• 1/2-13 UNC thread class 3A for consistent fit and reliable engagement
• Alloy steel construction with 36 to 43 HRC hardness for high load applications
• 5/16 inch hex socket drive compatible with standard hex keys and socket drivers
• Black oxide coating for mild corrosion resistance and low-glare appearance
• Conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC button socket cap screw for use in any application requiring a 1/2-13 thread and 2-1/2 inch grip length with a low-profile button head.

Installation Notes

Installation is performed using a 5/16 inch hex key or matching socket driver. Ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from engineering documentation or fastener manufacturer reference tables for 1/2-13 alloy steel fasteners. Avoid overtightening, which can strip threads or reduce clamp load integrity.
