Stainless steel bolts are versatile fasteners made from stainless steel alloys. With their unparalleled strength, corrosion resistance, and durability, stainless steel bolts have become a staple across countless industries.
Stainless steel contains a minimum of 10.5% chromium content. This chromium forms a passive layer of chromium oxide when exposed to oxygen, preventing further corrosion and rust. Other elements like nickel, molybdenum, titanium, copper, and nitrogen can also be added to enhance properties like strength, ductility, and high-temperature resistance. This alloying produces a material that is both strong and "stainless".
There are many compelling benefits that make stainless steel bolts a top choice:
Superior Corrosion Resistance
High Strength
Temperature Resistance
Aesthetic Appearance
Low Maintenance
Stainless bolts feature all the standard bolt head styles:
Hex: 6-sided head for wrench gripping with maximum torque transfer. The most common head type.
Socket: Recessed head allowing tight spaces and high torque with an Allen wrench.
Button: Low profile rounded head for smooth surfaces. Requires a socket wrench.
Flat: Flat recessed head for a flush surface. Needs a spanner wrench for torqueing.
Oval: Oval shaped head to prevent rolling. Used in vibrating machinery. Needs a socket wrench.
Factors to Consider When Selecting Bolts
In conclusion, stainless steel bolts offer unmatched corrosion resistance, strength, appearance, and low maintenance when constructed properly with the right alloys. Paying attention to engineering requirements and operating conditions allows selecting an optimal grade and style of stainless bolt for the application. With proper selection, stainless steel bolts will provide reliable, long-lasting service across industries.
