Stainless Steel Bolt and Nut for Heat Exchanger TubeSheet Application
Stainless steel nuts are fasteners commonly used in various applications where resistance to corrosion and wear is important. They are typically used with bolts or screws to secure components together. Here’s some basic information about stainless steel nuts:
Types of Stainless Steel Nuts:
- Hex Nuts: The most common type, featuring a hexagonal shape for use with a wrench.
- Slotted Hex Nuts: Similar to hex nuts but have slots that allow for safety wire installation to prevent loosening.
- Lock Nuts: These include nylon-insert lock nuts and prevailing torque lock nuts, which resist loosening due to vibration or other forces.
- Flange Nuts: Have a wide flange at one end that acts as an integrated washer, providing more surface area contact and better grip.
- Square Nuts: Feature a square profile and are often used in confined spaces.
- Wing Nuts: Designed with wings for manual tightening without tools.
Stainless steel nuts are made from different grades of stainless steel, such as 304, 316, and 410. Each grade offers varying levels of corrosion resistance, strength, and temperature tolerance.
