Bowmalloy 36605 Hex Nut 1/2-13 Grade 9 Steel

Product Description

The BOWMALLOY 36605 is a Grade 9 steel hex nut with a 1/2-13 thread size, designed for high-strength fastening applications in mechanical, industrial, and commercial construction settings. The clear zinc chromate finish provides corrosion resistance on exposed or semi-exposed assemblies. At 0.437 inches tall and 0.75 inches across the flats, this nut meets ANSI/ASME B18.2.2 dimensional standards. Hardness is rated at 26-36 HRC, making it suitable for joints under significant load or vibration. Plumbers, pipefitters, HVAC mechanics, and general contractors use Grade 9 nuts where standard hardware-grade fasteners are insufficient.

This hex nut is intended for use in structural, mechanical, and industrial assemblies requiring a high-strength, right-hand threaded fastener. The 1/2-13 UNC thread pattern is one of the most common sizes in trade applications, appearing in equipment mounting, pipe supports, structural brackets, and mechanical system connections. It pairs with any standard 1/2-13 bolt or threaded rod conforming to ANSI/ASME specifications.

Key Features

• Grade 9 steel construction with 26-36 HRC hardness for high-load fastening
• Clear zinc chromate finish for corrosion resistance
• 1/2-13 UNC right-hand thread for broad compatibility
• 0.75 inches across flats - accepts standard 3/4-inch wrench or socket
• Meets ANSI/ASME B18.2.2 fastener standard
• Compact profile at 0.437 inches tall for tight-clearance installations

Compatibility

Designed for use with any 1/2-13 UNC threaded bolt or stud conforming to ANSI/ASME B18.2.2 standards in structural, mechanical, or industrial applications.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with fastener torque requirements for the specific application and material. Always power down or de-energize associated equipment before working in proximity to live electrical or mechanical systems. Use a calibrated torque wrench to achieve the required clamp load specified in the project drawings or equipment manual. Do not mix Grade 9 nuts with lower-grade fasteners, as mismatched hardware grades can compromise joint integrity.
