Value Collection 837367PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 837367PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assembly, structural connections, and industrial fabrication. This fastener features a 1/2-13 UNC thread size and measures 2.5 inches in length under the head. It is partially threaded, which provides a shank section that resists shear forces and allows for controlled clamp load. The 3/8-inch hex drive requires a standard hex key or socket driver. Constructed from alloy steel with a zinc-plated finish, this screw is suited for environments where moderate corrosion resistance is required. Machinists, millwrights, and maintenance technicians are the typical end users.

This screw is used in residential and commercial mechanical equipment, industrial machinery, and structural assemblies where a socket-drive cap screw with a 1/2-13 UNC thread form is specified. The partial thread design makes it well suited for through-bolt applications and installations requiring a bearing surface along the shank. It meets ASTM B695 fastener standards. This screw is sold individually per package, with a minimum order quantity of 10 pieces.

Key Features

• 1/2-13 UNC thread size for compatibility with standard inch-series tapped holes
• 2.5-inch length under head accommodates thicker material stacks
• Partially threaded shank improves shear strength and alignment in through-bolt applications
• 3/8-inch hex drive for use with standard hex keys or socket drivers
• Alloy steel construction provides high tensile and yield strength
• Zinc-plated finish offers moderate corrosion protection per ASTM B695

Compatibility

Designed as a standard replacement or new-installation hex socket cap screw for applications specifying a 1/2-13 UNC partially threaded alloy steel fastener with a 3/8-inch hex drive.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 3/8-inch hex key or socket driver. Ensure the receiving tapped hole is clean and free of debris before threading to avoid cross-threading or damage to the zinc coating. Apply thread lubricant or thread-locking compound as required by the assembly specification. Always follow the equipment manufacturer torque specifications for 1/2-13 UNC fasteners in the relevant material and joint configuration.
