Value Collection HXI51750950 Hex Head Cap Screw

Product Description

The VALUE COLLECTION HXI51750950 is a partially threaded hex head cap screw designed for heavy-duty fastening applications in industrial, mechanical, and structural assemblies. This fastener measures 9-1/2 inches in length under head with a 1-3/4-12 thread size conforming to UNC thread standards. Manufactured from Grade 5 steel with a bright, uncoated finish, it delivers reliable tensile strength for high-load bolted connections. The partial threading allows for accurate clamping force distribution across thick or stacked material sections. Maintenance technicians, millwrights, and mechanical contractors specify this size for machinery mounting, equipment frames, and structural steel work.

This cap screw is suited for inch-system fastening applications where a coarse 1-3/4-12 UNC thread is required. Partial threading makes it appropriate for applications involving grip lengths where full threading would reduce clamping efficiency or introduce thread engagement issues through thick flanges, plates, or housings. It is commonly used in industrial equipment assembly, heavy machinery fabrication, and general structural bolting in both commercial and industrial settings.

Key Features

• 1-3/4-12 UNC thread size for inch-system heavy fastening applications
• 9-1/2 inch length under head accommodates thick material stackups
• Grade 5 steel construction provides high tensile strength for demanding load conditions
• Partially threaded shank improves clamping force distribution in thick-section assemblies
• Bright, uncoated finish suitable for dry indoor environments or where coating is not required
• Conforms to UNC thread standard for broad tooling and nut compatibility

Compatibility

Designed as a standard inch-system UNC hex head cap screw for use with 1-3/4-12 nuts and tapped holes in industrial machinery, structural steel, and heavy equipment assemblies.

Installation Notes

Installation is typically performed by millwrights, mechanical contractors, or maintenance technicians using appropriately rated hex sockets or open-end wrenches. Always ensure mating threads and tapped holes are clean and free of debris before installation. Follow applicable torque specifications per the relevant structural or mechanical standard for Grade 5 fasteners. Do not use this fastener in applications requiring corrosion-resistant or coated hardware unless additional surface protection is applied.
