Value Collection 581694BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 581694BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and structural components. It features a 3/4-10 UNC thread size with a 3-3/4 inch length under head and is partially threaded for positive clamping force in bolted joints. Driven with a 5/8 inch hex key, it is made from alloy steel with a black oxide coating that provides moderate corrosion resistance and a low-reflectance finish. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it a code-compliant choice for demanding mechanical and industrial work.

This cap screw is suited for use in manufacturing, maintenance, and repair environments where high tensile strength and a clean, recessed drive are required. The socket cap head profile allows installation in confined spaces where a standard hex bolt head would not clear. Partial threading ensures accurate load distribution across the clamped material. Machinists, millwrights, and maintenance technicians commonly install this fastener in machine frames, jigs, tooling plates, and equipment housings.

Key Features

• 3/4-10 UNC thread for standard inch-series bolted connections
• 3-3/4 inch length under head with partial threading for solid clamping
• 5/8 inch hex socket drive for use with standard Allen or hex keys
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides moderate corrosion resistance and reduced glare
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 3/4-10 UNC partially threaded socket cap fastener in alloy steel.

Installation Notes

Installation is performed by machinists or maintenance technicians using a calibrated 5/8 inch hex key or Allen driver. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated torque for the fastener grade as specified in ASME or ASTM reference tables. Apply thread lubricant or anti-seize compound as appropriate for the service environment to prevent galling on alloy steel threads.
