136017 - Silicon Bronze Nut Hex Heavy- 1" - 8 UNC (1 7/16" AF)

A heavy hex nut is made from a larger diameter hex across the flat (AF) and is thicker/taller than a standard finish nut.

The wider diameter AF provides a superior load-carrying capacity, strength and durability under stress, by increasing the area of load distribution, while the additional height increases the number of threads engaged.

Its six-sided hexagonal shape offers ease of installation and tightening with standard tools.

Made from solid silicon bronze, it combines excellent resistance to corrosion, especially in marine and harsh chemical environments, with reliable mechanical performance.

Ideal for situations where both strength and longevity are critical, this nut ensures secure fastening in heavy-duty assemblies.

*Please note this is the equivalent size but they are NOT interchangeable products.  

Applications

Crafted from solid Silicon Bronze, this heavy-duty hex nut combines outstanding corrosion resistance and moderate electrical conductivity with robust mechanical strength for critical fastening applications. Built to withstand harsh environmental conditions, silicon bronze naturally resists corrosion, essential properties for applications exposed to moisture, chemicals, or temperature fluctuations. The heavy-gauge construction ensures minimal deformation under sustained pressure, maintaining fastening integrity throughout extended service cycles. Ideal for electrical systems, telecommunications infrastructure, marine, oil, gas and industrial assemblies where material purity and long-term reliability are non-negotiable requirements.
