Value Collection HCI52000750 Hex Cap Screw Grade 5

Product Description

The VALUE COLLECTION HCI52000750 is a partially threaded hex head cap screw designed for heavy-duty fastening applications requiring a reliable, high-strength connection. Manufactured from Grade 5 steel with a bright uncoated finish, this fastener features a 2-4-1/2 inch thread size and a 7-1/2 inch length under the head measured by the UNC thread standard. The hex key size is 3 inches. At 1 pound, this is a substantial fastener suited for structural and mechanical assemblies where torque retention and shear strength matter. Licensed tradespeople and maintenance professionals working on industrial, commercial, or heavy mechanical systems rely on this class of fastener for consistent clamping performance.

This hex head cap screw is commonly used in industrial machinery assembly, structural steel connections, HVAC equipment mounting, and heavy mechanical installations. The partially threaded shank provides a smooth bearing surface that resists lateral movement in the joint, making it well suited for bolted connections where shank-to-hole fit is critical. The UNC thread form is standard across North American trade applications, ensuring broad compatibility with matching nuts and tapped holes in the field.

Key Features

• Grade 5 steel construction for high tensile strength in demanding mechanical applications
• Partially threaded shank provides a smooth bearing surface for improved joint stability
• UNC thread standard ensures broad compatibility with standard North American hardware
• Bright uncoated finish suitable for indoor and protected installations
• Hex key size of 3 inches accommodates standard heavy-duty wrenching tools
• 1 pound weight reflects substantial fastener mass appropriate for large-diameter bolting

Compatibility

Designed as a standard UNC partially threaded hex head cap screw for use with matching Grade 5 or higher hex nuts and tapped steel components in industrial and mechanical fastening applications.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with large-diameter fastener procedures. Always power down and de-energize associated equipment before beginning any bolted assembly or disassembly. Use a calibrated torque wrench appropriate for the fastener diameter and grade to achieve proper clamp load without overloading the joint. Follow applicable structural or mechanical codes for the specific application governing torque and inspection requirements.
