What are stainless steel fasteners?

A stainless steel fastener is a device that helps to mechanically join or affix two or more objects together. These fasteners create non-permanent joints that can be readily dismantled or removed without damaging the existing components. They showcase good corrosion resistance properties and work well in harsh environments. These fasteners possess superior strength and don’t disorientate under any stress or pressure. Stainless steel fasteners are designed in different specifications and sizes to suit different project requirements.

What are the disadvantages of stainless steel nut bolt?

Stainless steel nut bolt helps to hold different equipment efficiently; however, it has a few drawbacks. The nut bolt connections can come loose due to loose tightening, embedding issues, and gasket failure. Repeated exposure to air and moisture may also lead the nut bolt to rust and thereby leading to loose bolts.

What are Passivated stainless steel fasteners?

Passivated stainless steel fasteners are devices on which free iron contamination is removed from stainless steel. The contaminants are usually left behind after the machining or fabrication process. Passivated steel is a process to surface finish fasteners and thereby prevent corrosion

Why SS Fasteners are suitable for marine environments?

The SS fasteners are high-strength devices that can efficiently connect different equipment. These fasteners bolster superior corrosion resistance properties that allow them to work in marine environments. The fasteners also show good tolerance to oxidative media and pitting by acids. This makes them a viable option in the marine industry.

Advantages & disadvantages of Stainless steel bolts and nuts Coatings

Stainless steel bolts and nuts coatings make the entire device more tolerant to corrosive affluents. The coatings create a perfect bond and add an aesthetical outlook to the operation. These coatings may at times; however, be difficult to fit and align at the right place due to their geometry.
