Stainless steel heavy hex nuts are recommended when nuts will be exposed to corrosive environments and atmospheric conditions. They are non-magnetic and offer low electrical and thermal conductivity.
Due to their anti-rust properties, stainless steel heavy hex nuts withstand moist applications and environments including saltwater.
We offer off the shelf stock in 18-8 stainless steel nuts (300 series which includes 302, 302HQ, 303, 304 and 305 grades), 316 stainless steel (used in marine industries because of its greater pitting corrosion), and 410 stainless steel. Metric equivalents of the 300 series are A2 and of 316 is A4.
Non-common grades include
- Alloy 20
KD Fasteners’ stainless steel heavy hex nuts are slightly wider and thicker than the standard hex nut. They have a greater length of thread engagement and better resistance to stretching and widening. We offer stainless steel heavy hex nuts in sizes ranging from 1/32 inch to 4 inches in diameter. Metric sizes are also available.
