Value Collection HCI51500500G-001BX Hex Cap Screw 1-1/2-6x5 G5

Product Description

The VALUE COLLECTION HCI51500500G-001BX is a partially threaded hex head cap screw designed for heavy-duty fastening applications in mechanical, structural, and trade installations. It measures 5 inches in length under the head and carries a 1-1/2-6 UNC thread size, making it suitable for high-load bolted connections. The fastener is manufactured from Grade 5 steel with a hot-dipped galvanized finish that provides corrosion resistance in outdoor and moisture-exposed environments. HVAC, plumbing, and mechanical contractors encounter this size in equipment mounting, structural steel connections, and large-bore pipe support assemblies.

This cap screw is used in commercial and industrial installations where a large-diameter, coarse-thread fastener is required. Its partial threading allows the unthreaded shank to carry shear loads across the joint interface, which is a common requirement in structural bolting and heavy equipment anchoring. The hot-dipped galvanized coating makes it appropriate for exterior applications, galvanized steel structures, and other corrosive service environments.

Key Features

• 1-1/2-6 UNC thread — coarse pitch for high-load, heavy-duty connections
• 5-inch length under head — suits thick material stacks and deep clearance holes
• Partially threaded shank — carries shear load across joint interface
• Grade 5 steel construction — meets medium-high strength fastener requirements
• Hot-dipped galvanized finish — corrosion resistance for outdoor and wet environments
• Inch measurement system, UNC thread standard

Compatibility

Designed as a standard inch-series UNC hex head cap screw suitable for structural, mechanical, and equipment-mounting applications requiring a 1-1/2-6 thread and 5-inch grip length in galvanized steel assemblies.

Installation Notes

Installation should be performed by a qualified mechanic, ironworker, or trade professional using properly sized hex sockets or wrenches rated for 1-1/2-inch fasteners. Mating nuts and washers must match the UNC 1-1/2-6 thread specification and the same galvanized finish to minimize galvanic compatibility concerns. Always follow applicable structural or mechanical codes — such as AISC or ASME standards — for torque sequencing and inspection requirements on bolted connections of this size. De-energize or isolate equipment before working on any fastened assembly in an energized system.
