Value Collection 011601BR Hex Socket Cap Screw 1-1/2-6 Unc

Product Description

The VALUE COLLECTION 011601BR is a partially threaded hex socket cap screw designed for heavy-duty fastening applications in industrial, mechanical, and structural assemblies. It features a 1-1/2-6 UNC thread size with an 8-inch length under head, driven by a 1-inch hex socket. Constructed from alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for high-stress bolted joints where dimensional and mechanical consistency are required. Licensed tradespeople and industrial maintenance technicians are the primary installers.

This fastener is suited for large-bore mechanical assemblies, heavy equipment, industrial machinery, and structural fixtures that require a high-strength socket cap screw in a coarse-thread UNC profile. The partial threading is standard for longer-length cap screws of this type and allows the unthreaded shank to bear shear loads in precision-fit applications. The black oxide coating provides a clean, low-reflectance appearance and light surface protection in controlled environments.

Key Features

• 1-1/2-6 UNC coarse thread for high-load fastening in large-bore applications
• 8-inch length under head accommodates thick structural members and deep clamping stacks
• Partially threaded shank for improved shear load performance in precision bores
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides light corrosion resistance and low-glare appearance
• Driven by 1-inch hex socket for high-torque installation with standard drive tools

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application calling for a 1-1/2-6 UNC partially threaded alloy steel socket cap screw with an 8-inch length under head.

Installation Notes

Installation should be performed by a qualified mechanic or industrial maintenance technician using a 1-inch hex key or socket driver rated for the required torque. Ensure the mating thread is clean, free of damage, and matches the 1-1/2-6 UNC coarse thread profile before installation. Apply a compatible anti-seize compound or thread lubricant if specified by the equipment manufacturer to prevent galling on alloy steel threads. Never use an impact driver at full power without confirming the fastener and joint design can accommodate the resulting torque.
