Value Collection 581834BR Hex Socket Cap Screw 1-14 Unf

Product Description

The VALUE COLLECTION 581834BR is a fully threaded hex socket cap screw designed for high-strength fastening applications where a recessed drive is required. It features a 1-14 UNF thread and measures 2.5 inches in length under the head. The screw is machined from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. A 0.75-inch hex drive socket is required for installation. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding mechanical assemblies across industrial, manufacturing, and maintenance applications.

This cap screw is used in applications requiring a flush or recessed fastener head with high tensile strength. Typical installations include machine frames, jigs, fixtures, tooling plates, and structural assemblies where a fine-thread engagement is specified for vibration resistance or precise clamping force. The 1-14 UNF fine thread pitch provides greater thread engagement per inch compared to coarse thread equivalents, which is advantageous in metal-to-metal assemblies subject to dynamic loads.

Key Features

• Fully threaded 1-14 UNF fine thread for maximum thread engagement
• 2.5-inch length under head for deep fastening applications
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish for mild corrosion resistance and low-glare appearance
• 0.75-inch hex socket drive for high-torque installation
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 1-14 UNF fully threaded fastener with a 0.75-inch hex drive.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 0.75-inch hex key or socket driver. Ensure the mating threaded hole is clean and free of debris before installation. Apply thread lubricant or anti-seize compound as required by the assembly specification to achieve accurate clamp load. Follow applicable torque specifications from the equipment manufacturer or relevant ASME fastener standards.
