Value Collection 581696BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 581696BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical, industrial, and structural assemblies. The screw features a 3/4-10 UNC thread size and measures 4-1/4 inches in length under the head. Drive engagement is through a 5/8-inch internal hex socket. Constructed from alloy steel and finished with a black oxide coating, this fastener delivers solid tensile strength and moderate corrosion resistance in protected environments. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for applications where specification compliance is required.

This fastener is suited for general industrial and mechanical assembly work where a flush or low-profile cap head is preferred over an external hex configuration. Partial threading provides a shank bearing surface useful in close-tolerance joints and shear-load applications. Typical installation environments include machinery frames, jigs, fixtures, and structural brackets. Machinists, millwrights, and maintenance technicians are the primary installers in production and field service settings.

Key Features

• 3/4-10 UNC thread form for compatibility with standard unified coarse-thread nuts and tapped holes
• 4-1/4 inches length under head with partial threading to provide a load-bearing shank section
• 5/8-inch hex socket drive for use with Allen keys or hex bit drivers
• Alloy steel construction rated to ASTM A574 for high-proof-load and tensile-strength requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection in exposed assemblies
• Conforms to ASME/ANSI B18.3 dimensional standards for consistent fit across standard tooling

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for machinery, structural fixtures, and industrial equipment requiring a 3/4-10 UNC socket cap screw with a 4-1/4 inch length under head.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a 5/8-inch hex key or hex socket bit. Ensure the tapped hole or mating nut is clean and free of debris before installation. De-energize and lock out all equipment per applicable OSHA lockout/tagout procedures before fastener replacement in powered machinery. Do not substitute a lower-grade fastener in applications specifying ASTM A574 compliance.
