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
A2 / 304 stainless steel provides good general corrosion resistance for outdoor, clean industrial and food-related applications. Use anti-seize where stainless thread galling is a concern.
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.

Finish & Corrosion Protection
Plain / self colour: No applied coating. Stainless, brass and nylon parts are supplied plain; plain steel parts need oil, paint or protected environments.
Nominal dimensions per ASME B18.2.2. Weights are calculated from nominal dimensions and are a guide only (±10%). Values for fit and strength should be confirmed against the standard for critical applications.
