Value Collection 581695BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 581695BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 3/4-10 UNC thread size with 7-1/2 inches of length under the head, and is partially threaded to provide clamping force in bolted joint applications. The screw is machined from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection. A 5/8-inch hex drive socket is required for installation. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding load-bearing conditions.

This cap screw is used wherever high-tensile socket head fasteners are required, including machinery frames, tool fixtures, hydraulic components, and industrial equipment assemblies. The 3/4-10 UNC coarse thread pattern is well suited for applications involving softer base materials or where quick assembly and disassembly is needed. The partial threading allows the unthreaded shank to act as a precision dowel in close-tolerance bored holes. Suitable for both OEM manufacturing environments and field maintenance work performed by millwrights, machinists, and industrial maintenance technicians.

Key Features

• 3/4-10 UNC coarse thread for reliable engagement in a wide range of tapped holes
• 7-1/2 inches length under head accommodates deep or stacked component fastening
• Partially threaded shank provides shear strength and alignment in close-tolerance bores
• Alloy steel construction meets ASTM A574 high-strength socket head cap screw standard
• Black oxide finish reduces surface corrosion and minimizes light glare in exposed assemblies
• 5/8-inch hex socket drive for positive torque transfer with standard Allen or hex bit tooling

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for use in any tapped or through-hole assembly requiring a 3/4-10 UNC thread pattern and socket head drive.

Installation Notes

Installation requires a 5/8-inch hex key or socket bit driver rated for the torque demands of a 3/4-10 alloy steel fastener. Always ensure the mating tapped hole is clean, properly chased, and free of debris before driving the screw. Power down and de-energize any machinery before replacing or installing fasteners in mechanical assemblies. Do not substitute a metric hex key, as incorrect drive fit can strip the socket recess and compromise the fastener head.
