Value Collection 581604BR Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 581604BR is a hex socket cap screw designed for high-strength fastening in mechanical, industrial, and structural assemblies. Manufactured from alloy steel with a black oxide finish, this fully threaded fastener offers corrosion resistance and a clean, low-reflectance appearance suited to precision applications. The 5/8-11 UNC thread size and 1-3/8 inch length under head make it appropriate for medium-to-heavy load connections where reliable clamping force is required. Installation is performed with a 1/2-inch hex (Allen) key or socket driver. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, confirming dimensional accuracy and minimum tensile strength requirements expected in professional-grade fastener stock.

This socket cap screw is used across a wide range of trade and industrial applications, including machinery assembly, equipment mounting, fixture fabrication, and general mechanical maintenance. The recessed hex drive is well-suited to confined spaces where a standard hex head wrench cannot be used. Machinists, millwrights, maintenance technicians, and general contractors regularly stock this thread size and drive configuration for recurring repair and assembly work.

Key Features

• 5/8-11 UNC fully threaded profile for secure thread engagement along the full shank length
• 1-3/8 inch length under head for medium-depth fastening applications
• 1/2-inch hex drive for use with standard Allen keys or socket drive tools
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish offers moderate corrosion resistance and reduces surface glare
• Meets ASME/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance

Compatibility

Designed as a standard 5/8-11 UNC hex socket cap screw suitable for use in any application requiring an ASME/ANSI B18.3-compliant socket head fastener of this thread size and length.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 1/2-inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or thread-locking compound as required by the application. De-energize and lock out any equipment before replacing or installing fasteners in mechanical assemblies.
