Choose a hex nut with the right profile, material, and strength for your application.
Thin-Profile Hex Nuts
About half the height of standard-profile nuts, these fit in spaces with low clearance. You can also use them as jam nuts by threading them against another hex nut to hold it in place.
Medium-Strength Steel
 |
These Grade 5 or Class 04 nuts are your go-to for fastening most machinery and equipment. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.
Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
Steel—Best for dry environments since moisture will cause these nuts to rust.

Corrosion-Resistant Stainless Steel
|
18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
Super-Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these nuts won't degrade when exposed to harsh weather, salt water, and most chemicals.
Left-Hand-Thread Thin-Profile Hex Nuts
These nuts tighten when turned to the left. Use them with left-hand rods and screws to prevent counterclockwise-moving parts from loosening. About half the height of standard-profile nuts, these fit in spaces with low clearance. You can also use them as jam nuts by threading them against another hex nut to hold it in place.
