Value Collection HCI51250600G Hex Cap Screw 1-1/4-7 X 6 in Grade 5

Product Description

The VALUE COLLECTION HCI51250600G is a 1-1/4-7 UNC hex head cap screw with a 6-inch length under the head. Manufactured from Grade 5 steel with a hot-dipped galvanized finish, this partially threaded fastener delivers strong corrosion resistance and reliable clamping force across heavy-duty structural and mechanical assembly applications. The hex drive profile accepts standard wrenches and impact tools. At 2.58 pounds, this is a substantial fastener suited for demanding load-bearing connections where strength and weather resistance matter.

This screw is commonly used in structural steel connections, heavy equipment assembly, and outdoor or exposed installations where galvanized corrosion protection is required. The partial threading pattern provides a smooth shank section under the head, which is appropriate for applications requiring precise clamping of through-bolted joints. Trade professionals in construction, mechanical contracting, and industrial maintenance will find this fastener appropriate for both new installation and repair work.

Key Features

• Grade 5 steel construction for high tensile strength and dependable performance in load-bearing applications
• Hot-dipped galvanized finish provides heavy-duty corrosion resistance for outdoor and exposed environments
• Partially threaded shank allows full clamping force across joined materials without thread engagement in the grip zone
• 1-1/4-7 UNC thread standard ensures compatibility with standard inch-series nuts and tapped holes
• 6-inch length under head accommodates thick structural members and multi-layer assemblies

Compatibility

Designed for use with standard 1-1/4-7 UNC hex nuts and tapped holes conforming to inch-series thread standards in structural and mechanical fastening applications.

Installation Notes

Installation should be performed by qualified tradespeople familiar with structural fastening requirements and applicable codes. Always use a properly rated wrench or impact tool sized for the hex head. Confirm mating threads and nut grade are appropriate for the joint strength requirement before assembly. Follow applicable AISC, OSHA, or project engineering specifications for torque and inspection requirements.
