Value Collection 199509 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 199509 is a 1/2-13 UNC hex socket cap screw constructed from 18-8 stainless steel with a partially threaded shank. At 3 inches in length under the head, this fastener is driven with a standard hex key or Allen wrench and is well suited for mechanical assemblies, structural connections, and equipment installations where corrosion resistance is required. The 18-8 stainless steel alloy offers solid resistance to rust and oxidation, making it a reliable choice in wet or chemically exposed environments. Trade professionals in plumbing, HVAC, and general mechanical service regularly use this screw type for panel fastening, bracket mounting, and equipment securing applications.

This screw is appropriate for use in residential and commercial applications where a UNC-threaded, socket-drive fastener is specified. The partially threaded shank allows it to clamp two materials together with a smooth shank section passing through the clearance hole, providing a stronger clamping force than a fully threaded equivalent of the same length. Typical install scenarios include machinery mounting, equipment frames, and structural brackets where stainless steel is preferred over zinc-plated or plain steel fasteners.

Key Features

• 1/2-13 UNC thread specification for broad compatibility with standard tapped holes
• 3-inch length under head provides ample grip range for thicker assemblies
• Partially threaded shank improves clamping force and shank shear strength
• 18-8 stainless steel construction resists corrosion and oxidation
• Hex socket drive allows installation in confined spaces where a wrench cannot reach

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw for use in any application requiring a 1/2-13 UNC tapped hole and a socket-drive fastener.

Installation Notes

Installation is performed with a properly sized hex key or Allen wrench matching the socket drive of the screw head. Ensure the receiving tapped hole is clean and free of debris before threading. Do not overtighten, as stainless steel fasteners are susceptible to galling — applying an anti-seize compound to the threads is recommended practice. Follow all applicable mechanical and structural codes for the specific application.
