Value Collection 211299PR Flat Socket Cap Screw 1/2-13x2

Product Description

The VALUE COLLECTION 211299PR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head driven by a 5/16-inch hex socket, providing secure torque transfer in tight or recessed installations. The fastener is fully threaded with a 1/2-13 UNC thread form and measures 2 inches in overall length. Manufactured from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance suitable for general industrial and mechanical assembly work. Installation is performed with a standard hex key or Allen driver of the matching drive size.

This flat socket cap screw is suited for residential and commercial mechanical assemblies, machinery, tooling fixtures, and structural components where a low-profile countersunk head is required. The 1/2-13 UNC thread is a common coarse-thread standard found across a wide range of American fastener applications. The black oxide finish blends into dark or finished surfaces and provides light surface protection. Licensed tradespeople and skilled assemblers working in manufacturing, maintenance, and mechanical contracting will encounter this fastener type regularly.

Key Features

• 82-degree flat head for flush or countersunk seating in mating surfaces
• 5/16-inch hex socket drive for precise torque application
• Fully threaded 1/2-13 UNC coarse thread for maximum thread engagement
• Alloy steel construction for high tensile strength
• Black oxide finish for light corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 1/2-13 UNC flat socket cap screw per ASME/ANSI B18.3, compatible with any tapped or through-hole application specifying an 82-degree countersunk flat socket cap screw in that thread size and length.

Installation Notes

Installation requires a 5/16-inch hex key or Allen driver in good condition to avoid rounding the socket. Ensure the mating countersink is machined to an 82-degree included angle to achieve proper head seating. De-energize or lock out any equipment before fastener replacement or assembly work on live machinery, following applicable OSHA lockout/tagout procedures. Do not exceed the rated torque specification for the fastener grade as defined by the applicable ASME or ASTM standard.
