Value Collection -36660-B Hex Nut 1-8 Grade 2H

Product Description

The VALUE COLLECTION -36660-B is a heavy hex nut with a 1-8 thread size and Grade 2H classification. Heavy hex nuts are designed for high-strength bolting applications where a standard hex nut does not provide sufficient bearing area or load resistance. Grade 2H designates a heavy hex nut manufactured to ASTM A194 standards, making it suitable for use with high-strength bolts and studs in structural, pressure vessel, and industrial fastening applications. Plumbers, pipefitters, millwrights, and general contractors use this nut when code or design requirements call for ASTM A194 Grade 2H hardware.

This nut is used in heavy industrial and construction settings where bolted joints must withstand elevated loads, vibration, or pressure. Typical applications include pipe flange assemblies, structural steel connections, and equipment mounting. The 1-8 thread designation indicates a 1-inch nominal diameter with 8 threads per inch, a common coarse-thread specification in industrial fastening. This SKU is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• Grade 2H classification meets ASTM A194 requirements for heavy hex nuts used in high-strength bolting
• 1-8 thread size: 1-inch nominal diameter with 8 threads per inch (coarse thread series)
• Heavy hex geometry provides increased bearing surface compared to standard hex nuts
• Suitable for structural, pressure vessel, and industrial piping flange applications
• Minimum order quantity of 100 pieces per order

Compatibility

Designed for use with 1-8 threaded bolts and studs in heavy industrial and structural applications where ASTM A194 Grade 2H hardware is specified.

Installation Notes

Installation is performed by licensed pipefitters, ironworkers, millwrights, or qualified mechanics depending on the application. Always de-energize, depressurize, or isolate the assembly before removing or installing fasteners in live systems. Follow applicable ASME, AISC, or ASME B31 piping code torque and installation procedures as required by the project specification. Do not mix Grade 2H hardware with lower-grade fasteners in the same joint.
