About Nuts, Materials, and Finishes

18-8 Stainless Steel Hex Nuts

These nuts have good chemical resistance and may be mildly magnetic.

Metric 18-8 Stainless Steel Hex Nuts

These nuts have good chemical resistance and may be mildly magnetic. Metric 18-8 stainless steel is also known as A2 stainless steel.

Metric Fine-Thread 18-8 Stainless Steel Hex Nuts

Super-Corrosion-Resistant 316 Stainless Steel Hex Nuts

These nuts have excellent chemical resistance and can be used in saltwater environments.

Metric Super-Corrosion-Resistant
316 Stainless Steel Hex Nuts

These metric nuts have good chemical resistance and may be mildly magnetic.

18-8 Stainless Steel Thin Hex Nuts

These nuts have good chemical resistance and may be mildly magnetic.

Metric 18-8 Stainless Steel Thin Hex Nuts

Useful in low-clearance applications, these metric nuts are roughly half the height of standard hex nuts, but aren’t as strong. All are 18-8 stainless steel, which is nearly as strong as steel but won’t rust in outdoor, washdown, and other corrosive environments.

Metric Fine-Thread 18-8 Stainless Steel Thin Hex Nuts

Made with fine-pitch threads, vibration is less likely to loosen these metric nuts than those with coarse-pitch threads since the threads sit closer together. Also called jam nuts, they are roughly half the height of standard hex nuts, so they’re good for applications with low clearance.
