Bowmalloy BOW-36620-11/8 Hex Nut 1-1/8-12 Grade 9

Product Description

The BOWMALLOY BOW-36620-11/8 is a heavy-duty hex nut machined from Grade 9 steel and finished with a Bowma-Guard protective coating. It carries a 1-1/8-12 thread size with a right-hand thread direction and a 2B thread fit class, making it suitable for high-strength fastening applications where vibration resistance and clamping force are critical. The nut measures 1.688 inches across the flats and 1.176 inches in height. Hardness is rated at 26-36 HRC. Licensed trade professionals and industrial mechanics rely on this grade of fastener in demanding structural and mechanical assemblies.

This hex nut is well suited for use in heavy equipment, industrial machinery, and structural installations that demand Grade 9 tensile strength. The Bowma-Guard finish provides corrosion resistance for applications in moderately harsh environments. It is sold in packages of 10 and fits standard 1-1/8-12 threaded rod, bolt, and stud configurations commonly found in commercial and industrial settings.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional familiar with high-strength fastener specifications. Always clean and inspect mating threads before assembly to ensure proper 2B fit class engagement. Use a calibrated torque wrench appropriate for Grade 9 hardware and refer to the applicable engineering or structural specification for torque requirements. Do not mix Grade 9 nuts with lower-grade bolts or studs.
