Last Updated on March 13, 2023 by Marsh Fasteners

Stainless steel nuts or stainless steel fasteners come in all shapes and sizes and each design offers distinct advantages. However, many people are not completely aware of the variety and its benefits. We are specialists in the industry and our focus is on quality products. This informative blog has been compiled to shed some light on the above subject, so you are better informed when purchasing supplies.

Hex Nuts

The most common types of stainless steel nuts are hex nuts, which are standardized with six sides. The unique design allows for the strong grip of a wrench at various angles. The result is excellent convenience, as hard-to-reach places where a wrench can’t turn 360 degrees can be accessed with ease for repairs, installations, and so forth. 

Hex nuts are commonly used with the following applications:

  • Metal and wood 
  • Anchor shackles
  • Stainless steel fasteners with external threading such as bolts and screws with over 1/4-20 thread.
  • Flathead, pan head, oval head, round head, truss head, and hex head cap bolt screws, larger-sized socket head cap screws such as flat, button, and cap head screw bolts
  • Locking mechanisms

Marsh Fasteners has hex nuts made of various stainless steel grades. The hex stainless steel nuts are popular with a variety of production applications and contain a right-hand thread. 

Wing Nuts

These are nuts designed with two flat wings on either side and allow for easy tightening or loosening using only fingers. Unfortunately, these are not designed with high strength in mind and are most often utilized where convenience offers more value than strength.

The 4 types of wingnuts include:

  • Type A: Stainless steel wingnuts
  • Type B: Hot forged wingnuts
  • Type C: Die casts wingnuts
  • Type D: Carbon steel sheet metal wingnuts

Wingnuts can be used in a variety of applications including:

  • Industrial, 
  • Construction
  • OEM applications where corrosion resistance is a primary factor

MarshFasteners have wingnuts that are designed to be used where you want to loosen the nut by hand with your fingers. The wingnuts are made from 18-8 /304-grade stainless steel.

Cap Nuts

These are stainless steel nuts with a dome rather than a flat top. Interestingly, they facilitate aerodynamics which would prove ideal on aircraft and vehicles but is commonly utilized for aesthetic purposes on handrails and steel furnishings.

Applications for cap nuts:

Hex nuts are for general purpose and are comprised of a six-sided nut. Hex nuts are typically used with a bolt or machine screw. 

Marsh Fasteners fine-pitch cap nuts include acorn cap nuts, which creates a beautiful touch to projects. They are made of A2 stainless steel grade for corrosion resistance and produced to DIN Specifications

Square Nuts

Square nuts are four-sided nuts that offer greater resistance to loosening. The reason for this is that the underside has a greater surface area than standard hex nuts and can grip more effectively when fully tightened.

Square nut applications:

  • Utility industry
  • Used as a blind nut for furniture
  • Rail channels
  • Used as a foundation in metal channels of stainless steel fasteners
