Value Collection 063143PS Flat Socket Cap Screw 316 Ss

Product Description

The VALUE COLLECTION 063143PS is a flat socket cap screw designed for fastening applications that require a flush or countersunk head profile. The screw features a 5/16-inch hex socket drive and an 82-degree flat head angle, making it suitable for installations where a low-profile fastener is needed. Manufactured from 316 stainless steel, this screw offers strong resistance to corrosion, including exposure to chlorides and marine environments. The 1/2-13 UNC thread is fully threaded across the 1-1/4-inch overall length, providing consistent thread engagement through the full shank.

This flat socket cap screw is well-suited for use in plumbing, marine, food processing, chemical handling, and industrial maintenance applications where corrosion resistance is a primary concern. The 316 stainless steel grade performs reliably in wet and chemically active environments where standard carbon steel or 18-8 stainless fasteners may be insufficient. It is a practical choice for mechanical assemblies, structural connections, and equipment fabrication requiring countersunk fastening with hex drive access.

Key Features

• 82-degree flat head profile for flush and countersunk installations
• 5/16-inch hex socket drive for standard Allen key or hex bit access
• 316 stainless steel construction for superior corrosion and chemical resistance
• 1/2-13 UNC thread standard for broad compatibility with inch-system hardware
• Fully threaded over 1-1/4-inch overall length for maximum thread engagement

Compatibility

Designed as an OEM-style replacement or standard-fitment fastener for applications requiring a 1/2-13 UNC flat socket cap screw in 316 stainless steel with an 82-degree head angle.

Installation Notes

Installation is typically performed by millwrights, pipefitters, plumbers, or maintenance technicians using a 5/16-inch hex key or socket bit. Countersink the mating material to the correct 82-degree angle before driving the screw to ensure proper seating. Apply appropriate anti-seize compound when fastening into stainless or dissimilar metals to prevent galling. Follow applicable mechanical or structural codes for torque requirements based on joint design and material.
