Frequently Asked Questions (FAQs)

1. What is the best grade of stainless steel bolts?

If a bolt is stainless steel, we recommend replacing with stainless steel. Furthermore, if a bolt grade is 316 stainless, prized for extra corrosion resistance, we always recommend using 316 when replacing and not a lesser bolt grade such as 304 or 303.

2. Is stainless steel good for bolts?

Stainless Steel Fasteners are, most importantly, corrosion resistant. They have an excellent life cycle, are environmentally friendly and are 100% Recyclable. They are also resistant to high heat as well as extremely cold temperatures making stainless steel fasteners the material of choice for almost any application!

3. Are stainless steel bolts weak?

In fact, due to their low carbon content, many stainless steel alloys cannot be hardened through heat treatment. Therefore, when compared to regular steel, the stainless alloys used in bolts are slightly stronger than an un-hardened (grade 2) steel but significantly weaker than hardened steel fasteners.

4. Will stainless steel bolts rust?

Stainless steel screws achieve elevated rust resistance thanks to their chromium-oxide composition. Fasteners with a chromium oxide coating provide extra resistance to rust and corrosion by using the added oxygen as a protective layer.
