Value Collection 581699BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 581699BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fabrication, and industrial maintenance. This fastener features a 3/4-10 UNC thread size with a 9-inch length under head and is partially threaded along its shank. The 5/8-inch hex drive accepts a standard hex key or Allen wrench for installation and removal. Constructed from alloy steel with a black oxide coating, this screw offers corrosion resistance and a low-reflectance finish suited to shop and field environments. Licensed tradespeople and maintenance mechanics handling structural or equipment assemblies will find this screw built to meet ASME/ANSI B18.3 and ASTM A574 standards.

This cap screw is suited for use in machine frames, industrial fixtures, heavy equipment, and fabricated steel assemblies where a recessed-drive, high-torque fastener is required. The partial thread design allows the unthreaded shank to act as a shoulder in clearance-hole applications, providing precise alignment and shear load resistance. It is appropriate for both original equipment assembly and maintenance replacement in commercial and industrial settings.

Key Features

• 3/4-10 UNC thread size for high-strength clamping force in large assemblies
• 9-inch length under head accommodates deep grip or thick stack-up applications
• Partially threaded shank provides shear resistance and alignment in clearance holes
• 5/8-inch hex socket drive for use with standard hex keys or Allen drive tools
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide coating provides mild corrosion resistance and low-reflectance appearance

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for use in any application requiring a 3/4-10 UNC partially threaded fastener with a 9-inch length under head.

Installation Notes

Installation is performed with a 5/8-inch hex key or Allen drive tool; ensure the drive tool is fully seated before applying torque to avoid stripping the socket. De-energize and lock out any equipment before fastener installation or removal in live mechanical systems. Consult applicable torque specifications from the equipment manufacturer or a current fastener reference standard, as no torque value is specified in the product data. Apply a thread lubricant or anti-seize compound if recommended by the assembly specification to ensure consistent clamp load.
