Value Collection R56000966 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION R56000966 is a hex socket cap screw designed for high-strength fastening applications where corrosion resistance is essential. Manufactured from 316 stainless steel with a bright, uncoated finish, this fastener features a 1/2-13 UNC thread size and measures 4 inches in length under the head. It accepts a 3/8-inch hex drive, making it compatible with standard hex keys and socket drive tools. The 316 stainless steel construction provides superior resistance to chlorides and harsh environments compared to 304 grades. This screw is suited for mechanical assemblies, structural connections, and equipment installations handled by machinists, pipefitters, millwrights, and maintenance technicians.

This fastener is commonly used in industrial, marine, chemical processing, and food-service environments where standard carbon steel hardware would be prone to corrosion. The 1/2-13 UNC coarse thread is a widely used standard pitch, making this screw appropriate for general-purpose tapped-hole applications and through-bolt assemblies in both light and heavy-gauge components. It is sold individually with a minimum order quantity of 5 pieces.

Key Features

• 316 stainless steel construction for enhanced corrosion resistance in marine and chemical environments
• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 4-inch length under head suits deep-reach fastening applications
• 3/8-inch hex socket drive for use with standard hex keys and socket drivers
• Bright, uncoated finish — no coating to flake, chip, or interfere with dimensional tolerances

Compatibility

Designed as an OEM-style replacement or standard-supply fastener for any assembly requiring a 1/2-13 UNC hex socket cap screw with a 4-inch length under head and 3/8-inch hex drive in 316 stainless steel.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 3/8-inch hex key or socket driver. Verify that mating threads are clean and free of debris before installation. When installing 316 stainless fasteners into stainless threaded holes, apply an anti-seize compound to prevent galling. Follow applicable torque specifications from your assembly drawings or engineering standards — do not use impact drivers at full power on stainless fasteners.
