Description
Overview
Nuts provide the internal thread in a bolted joint. The nut must match the bolt or threaded rod size, pitch, material compatibility and required strength class.
This selected size is specified with length 1-1/8 in.
Sold in multiples of '1 pieces. 1 Box = '1 pieces.
Material, Grade & Strength
A4 / 316 stainless steel provides enhanced corrosion resistance for coastal, marine, chemical and harsh outdoor environments.
Finish & Corrosion Protection
Stainless products rely on the corrosion resistance of the stainless material rather than a separate plated coating.
Typical Uses
Nuts are used with bolts, set screws, studs and threaded rod to create clamped joints that can be assembled, adjusted and serviced.
Technical Tips
- Match the nut thread size and pitch to the mating fastener.
- Use a compatible property class for high tensile bolts.
- Use locking nuts or thread locking methods where vibration is present.
- Use anti-seize on stainless-on-stainless assemblies where galling is a risk.
Selection Advice
Select the product by matching the thread, size, material, finish and function to the assembly. Avoid choosing only by appearance or a partial part number.
