Value Collection R50000349 Hex Nut 1-1/2-6 Unc Steel

Product Description

The VALUE COLLECTION R50000349 is a heavy-duty steel hex nut threaded to the 1-1/2-6 UNC standard with a right-hand thread direction. Measuring 2.25 inches across the flats and 1.317 inches in height, this nut is sized for large-diameter fastening applications common in mechanical, structural, and industrial assembly work. The uncoated finish means the steel is left bare, making it suitable for environments where a secondary coating or paint will be applied after assembly. Plumbers, pipefitters, millwrights, and general contractors working with heavy structural connections will find this a straightforward, reliable fastener for demanding applications.

This hex nut is appropriate for use in heavy mechanical assemblies, structural steel connections, pipe flange installations, and equipment mounting where a 1-1/2-6 UNC threaded bolt or stud is specified. The coarse UNC thread pitch is well-suited for applications involving thick or softer base materials where quick engagement and reliable clamping force are priorities. It is not designed to meet military specifications.

Key Features

• 1-1/2-6 UNC coarse thread standard for broad compatibility with standard bolts and studs
• Right-hand thread direction for conventional tightening and loosening
• Steel construction provides high tensile strength for structural and mechanical use
• 2.25 inches across flats for use with standard heavy-duty wrenches and sockets
• Uncoated finish allows for post-assembly coating, plating, or painting as needed
• Does not meet military specifications — suited for commercial and industrial use

Compatibility

Designed for use with 1-1/2-6 UNC threaded bolts, studs, and threaded rod in commercial, industrial, and structural assembly applications.

Installation Notes

Installation should be performed by a qualified tradesperson using an appropriately rated wrench or socket sized for 2.25-inch hex flats. Always ensure the mating bolt or stud thread specification matches 1-1/2-6 UNC before assembly. Inspect threads for damage or contamination before installation. Follow applicable torque guidelines from the equipment manufacturer or structural engineer of record.
