Value Collection 581732BR Hex Socket Cap Screw 3/4-16 Unf

Product Description

The VALUE COLLECTION 581732BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and a clean, low-reflectance appearance suitable for precision assemblies. The screw features a 3/4-16 UNF thread size and measures 3 inches in length under the head, with a 5/8-inch hex drive for use with standard Allen or hex key tools. Machinists, maintenance technicians, and assembly professionals install this type of fastener where fine-thread engagement and high tensile load capacity are required.

This screw is suited for applications in general industrial machinery, tooling fixtures, and mechanical assemblies where a fine-thread UNF pattern provides superior holding strength and vibration resistance compared to coarse-thread alternatives. Partial threading allows for a smooth shank section, which is common in applications requiring precise hole alignment or where the fastener must pass through a clearance bore before engaging the threaded receiver. It conforms to ASME/ANSI B18.3 and ASTM A574 standards.

Key Features

• 3/4-16 UNF fine-thread profile for high tensile strength and vibration resistance
• 3-inch length under head with partial threading for clearance-bore applications
• 5/8-inch hex socket drive compatible with standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or standard fastener for industrial machinery, tooling, and mechanical assemblies requiring a 3/4-16 UNF partially threaded hex socket cap screw per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 5/8-inch hex key or socket drive. Ensure the mating thread is clean and free of debris before fastening, and confirm the threaded insert or tapped hole meets the UNF 3/4-16 specification. De-energize and lock out any equipment before servicing fasteners in mechanical assemblies. Do not use an impact driver without verifying torque requirements for the specific application through published engineering data.
