Value Collection 011340PR Hex Socket Cap Screw 7/16-20 Unf

Product Description

The VALUE COLLECTION 011340PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 7/16-20 UNF thread size with full threading along a 1-1/4-inch length under head, driven by a 3/8-inch hex socket drive. Constructed from alloy steel with a black oxide finish, this screw delivers solid corrosion resistance and maintains dimensional integrity under load. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for applications where fastener grade and traceability matter. Machinists, millwrights, and maintenance technicians are the primary installers.

This fastener is suited for use in precision mechanical assemblies, hydraulic component mounting, and machine tool applications where a fine-thread UNF pattern is required for tighter thread engagement and vibration resistance. The black oxide coating helps control surface corrosion in moderate-exposure environments. The 7/16-20 UNF thread specification makes it a common choice in applications that demand finer thread pitch over standard UNC fasteners of the same diameter.

Key Features

• 7/16-20 UNF fine thread for increased thread engagement and vibration resistance
• 1-1/4-inch length under head, fully threaded
• 3/8-inch hex socket drive for standard Allen key or hex bit installation
• Alloy steel construction meeting ASTM A574 specification
• Black oxide finish for moderate corrosion and surface protection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style hex socket cap screw for mechanical assemblies and industrial equipment requiring a 7/16-20 UNF fine-thread fastener with a 3/8-inch hex drive.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a calibrated hex key or hex socket driver sized at 3/8 inch. De-energize and lock out all equipment before fastener replacement or torquing operations in live machinery. Apply thread lubricant or thread-locking compound as required by the equipment manufacturer. Follow applicable ASME B18.3 torque guidelines for alloy steel socket cap screws of this diameter and thread class.
