Value Collection 011597BR Hex Socket Cap Screw 1-1/2-6 Unc

Product Description

The VALUE COLLECTION 011597BR is a partially threaded hex socket cap screw designed for high-load fastening applications in structural, mechanical, and industrial assemblies. It features a 1-1/2-6 UNC thread size and measures 6.5 inches in length under the head. The 1-inch hex drive socket interface accepts a standard hex key or Allen driver. Manufactured from alloy steel with a black oxide coating, this fastener delivers solid corrosion resistance and reduced surface glare in demanding service environments. It meets ASME/ANSI B18.3 and ASTM A574 standards. Licensed tradespeople and industrial maintenance technicians typically install this screw where high tensile strength and controlled torque seating are required.

This cap screw is suited for heavy-duty mechanical assemblies, machine bases, tooling fixtures, and structural steel connections where a recessed drive and full bearing surface under the head are needed. The partial threading allows the unthreaded shank to serve as a precision locating feature in close-tolerance bores, making it a common choice in manufacturing, maintenance, and equipment fabrication environments. Sold individually, it fits procurement needs for single-unit replacement or low-quantity repair work.

Key Features

• 1-1/2-6 UNC thread size for heavy-duty fastening applications
• 6.5 inches length under head with partial threading for shank-fit applications
• 1-inch hex socket drive accepts standard hex keys and torque drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and low-reflectance surface
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for industrial machinery, structural assemblies, and mechanical equipment requiring 1-1/2-6 UNC partially threaded hex socket cap screws per ASME/ANSI B18.3.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a properly sized 1-inch hex key or torque wrench socket adapter. De-energize and lock out any machinery before fastener removal or installation per applicable OSHA lockout/tagout procedures. Apply thread lubricant or anti-seize compound only if specified by the equipment manufacturer, as this will affect torque-to-clamp-load values. Inspect the mating tapped hole for thread damage or contamination before seating the fastener.
