Value Collection 581704BR Hex Socket Cap Screw 1-12 Unf

Product Description

The VALUE COLLECTION 581704BR is a hex socket cap screw designed for high-strength bolted joint applications in industrial, mechanical, and structural assemblies. Manufactured from alloy steel with a black oxide finish, this fastener provides good corrosion resistance in moderate environments while maintaining the mechanical strength expected from an ASME/ANSI B18.3 and ASTM A574 compliant cap screw. The 3/4-inch hex drive accepts a standard hex key or socket driver. With a 7-inch length under head and a 1-12 UNF thread form, this screw is suited for applications requiring fine thread engagement and high clamping force. Installation is performed by qualified mechanical or maintenance trades.

This cap screw is appropriate for use in machinery, tooling fixtures, hydraulic assemblies, and structural connections where fine unified thread (UNF) engagement is specified. The partially threaded shank allows the unthreaded portion to serve as a precision locating surface within a bored hole. The black oxide finish reduces light reflection and offers light surface protection in dry or lightly oiled service environments.

Key Features

• 1-12 UNF thread form for fine-thread, high-clamping-force applications
• 7-inch length under head with partial threading for shank-fit installations
• 3/4-inch hex socket drive compatible with standard hex keys and drive sockets
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides light corrosion resistance and reduced reflectivity
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style or replacement hex socket cap screw for industrial and mechanical assemblies specifying a 1-12 UNF partially threaded fastener with a 3/4-inch hex drive.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel familiar with fastener torque specifications for the application. Always verify thread engagement depth and hole condition before installation. Use the correct 3/4-inch hex key or socket driver to avoid drive damage. Follow applicable machine or structural assembly specifications for proper torque values, as none are specified for this fastener in isolation.
