Value Collection 307190BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 307190BR is a partially threaded hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. It features a 3/4-10 UNC thread size and measures 5-1/2 inches in length under the head, making it suitable for thick-stock connections where a standard-length fastener falls short. The alloy steel construction meets ASTM A574 standards, and the black oxide finish provides mild corrosion resistance while reducing light reflection. A 9/16-inch hex drive socket is required for installation. This screw is typically installed by millwrights, machinists, maintenance technicians, and mechanical contractors.

This cap screw is used in general industrial machinery, structural steel assemblies, equipment frames, and maintenance-repair-operations (MRO) applications where a strong, socket-drive fastener is required. The partial threading provides a smooth shank section for precise bolt alignment and bearing-load applications. It is suited for use wherever a 3/4-10 UNC thread pattern and a 5-1/2-inch under-head length are specified.

Key Features

• ASTM A574 alloy steel construction for high tensile strength
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• Partially threaded shank allows for precise alignment and shear-load distribution
• 3/4-10 UNC thread for wide compatibility with standard inch-series tapped holes
• 9/16-inch hex socket drive for high-torque installation with standard tooling
• 5-1/2-inch length under head accommodates thick material stack-ups

Compatibility

Designed for use in any application requiring a 3/4-10 UNC partially threaded hex socket cap screw with a 5-1/2-inch under-head length. Verify thread engagement depth and clearance requirements against your assembly drawings before installation.

Installation Notes

Installation is typically performed by qualified machinists, millwrights, or mechanical maintenance technicians. Power down and de-energize all equipment before accessing fastener locations on live machinery. Use a calibrated torque wrench with a 9/16-inch hex socket bit and follow the torque specifications provided in your equipment or assembly documentation. Do not substitute thread lubricants or anti-seize compounds without confirming compatibility with the joint design.
