Value Collection 581970BR Hex Socket Cap Screw 1-1/2-12 Unf

Product Description

The VALUE COLLECTION 581970BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and a consistent surface hardness suited to demanding service environments. The 1-inch hex drive accepts standard hex keys and socket tooling. At 7 inches in length under the head and threaded to 1-1/2-12 UNF specification, this screw is sized for heavy-duty bolted joints where fine thread engagement and clamping load are critical.

This cap screw is commonly used in machine tool assemblies, hydraulic components, industrial equipment, and structural fixtures where a recessed drive head and fine-thread UNF profile are required. The black oxide coating makes it suitable for light indoor corrosion resistance in controlled environments. Maintenance technicians, millwrights, and mechanical assemblers working on heavy equipment will encounter this fastener in applications demanding both thread precision and high tensile strength.

Key Features

• 1-1/2-12 UNF fine thread for precise clamping and vibration resistance
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide coating provides mild corrosion and abrasion resistance
• Partially threaded shank maintains shear strength along the unthreaded body
• 1-inch hex socket drive compatible with standard hex keys and socket drivers
• 7-inch length under head accommodates thick or stacked joint assemblies

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 1-1/2-12 UNF partially threaded fastener with a 1-inch hex drive.

Installation Notes

Installation should be performed by qualified mechanical technicians or millwrights following applicable ASME or equipment manufacturer torque guidelines for the fastener grade and thread size. De-energize and lock out all equipment before fastener installation or removal. Use a properly sized 1-inch hex key or socket driver to avoid drive damage. Verify thread engagement depth and joint material compatibility before final torque.
