Value Collection HCI50500550G-025BX Hex Cap Screw 1/2-13

Product Description

The VALUE COLLECTION HCI50500550G-025BX is a partially threaded hex head cap screw engineered for general-purpose fastening applications in construction, mechanical assembly, and structural installations. This fastener measures 1/2-13 thread size with a 5-1/2 inch length under head, following Unified National Coarse (UNC) thread standards. Manufactured from Grade 5 steel, it delivers the tensile strength required for demanding bolted connections. The hot-dipped galvanized finish provides corrosion resistance suitable for outdoor and exposed environments. Licensed tradespeople and contractors rely on this screw where a standard hex wrench or impact driver is the tool of choice.

This hex head cap screw is suited for residential and commercial structural work, equipment mounting, framing hardware, and general mechanical assemblies where a UNC 1/2-13 fastener with partial threading is specified. Partial threading allows for increased clamping force between joined materials, making it appropriate for through-bolting applications in wood, steel, and fabricated assemblies. It is packaged individually with a minimum order quantity of 25 pieces, making it practical for job-lot procurement on active worksites.

Key Features

• 1/2-13 UNC thread size for compatibility with standard 1/2-inch nuts and tapped holes
• 5-1/2 inch length under head accommodates thicker material stacks and through-bolt applications
• Grade 5 steel construction meets mid-range tensile strength requirements for structural fastening
• Hot-dipped galvanized finish provides corrosion resistance for outdoor and moisture-exposed installations
• Partially threaded shank increases clamping force and prevents thread binding in unthreaded material
• Standard hex head drive works with common wrenches, sockets, and impact tools

Compatibility

Designed as a standard UNC 1/2-13 hex head cap screw compatible with any application requiring a 1/2-13 thread pitch and a 5-1/2 inch grip length, including use with standard 1/2-inch hex nuts, washers, and threaded inserts conforming to UNC specifications.

Installation Notes

Installation is performed by general contractors, electricians, plumbers, HVAC technicians, and maintenance trades as part of equipment mounting or structural assembly. Always use an appropriate torque wrench or impact tool calibrated to the joint specification for Grade 5 hardware. Ensure mating nuts and tapped holes conform to UNC 1/2-13 standards before installation. Do not substitute this fastener in applications requiring Grade 8 or metric-equivalent tensile ratings without engineering verification.
