Value Collection 581705BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 581705BR is an alloy steel hex socket cap screw with a 3/4-10 UNC thread size and a 5/8 inch hex drive. At 11 inches in length under the head, this is a heavy-duty fastener suited for high-stress mechanical assemblies. The black oxide finish provides mild corrosion resistance and reduces light reflection on exposed hardware. Partially threaded along its shank, it is designed for applications requiring a smooth bearing surface between clamped components. Machinists, maintenance mechanics, and industrial tradespeople use this fastener where both high tensile load and precise fitment are required.

This screw is used in general industrial, manufacturing, and mechanical maintenance applications where 3/4-10 UNC threaded connections are specified. The partial threading makes it well suited for through-bolt configurations and applications demanding a controlled grip length. It is commonly found in heavy equipment assembly, structural fixtures, and machine frames where alloy steel strength is necessary and a standard hex socket drive is preferred for torque application with an Allen wrench or hex bit socket.

Key Features

• 3/4-10 UNC thread size for use in standard inch-series tapped holes
• 11 inch length under head provides extended reach for deep-stack assemblies
• Partial threading leaves a smooth shank section for precise grip-length control
• 5/8 inch hex socket drive accepts standard Allen keys and hex bit sockets
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide coating offers mild corrosion resistance and a low-reflectance appearance

Compatibility

Designed for use in any application requiring a 3/4-10 UNC hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 specifications. Fits standard 3/4-10 UNC tapped holes in steel, iron, and aluminum structures.

Installation Notes

Installation is performed with a 5/8 inch hex key or Allen-style socket driver. Ensure the mating tapped hole is clean and free of debris before threading. Follow applicable torque specifications from ASME or equipment OEM documentation for 3/4-10 UNC alloy steel fasteners. Apply thread lubricant or anti-seize compound as appropriate for the service environment to prevent galling.
