Stainless Steel Screws FAQs
What are stainless steel screws?
Stainless Steel Screws are screws which are made from steel which is alloyed with Chromium and Nickel to increase its corrosion resistance.
Screws made from stainless steel material are therefore resistant to rusting and have much better corrosion resistance than Zinc plated screws.
There are 3 main grades of stainless steel used for manufacturing screws.
A2 Grade Stainless Steel (302,304) this give a good level of corrosion resistance in standard neutral non marine environments.
A4 Grade Stainless Steel (316) this gives good levels of corrosion resistance in Marine environments.
Hardened Stainless Steel Grade 410 (C1) this is stronger and harder than both A2 and A4 Grade Stainless Steel and can self-drill mild steel.
410 Grade Stainless Steel gives good levels of corrosion resistance but not quite as good as A2 Grade Stainless Steel.
What types of stainless screws are available?
There are many types of screws available in Stainless Steel including Wood Screws, Decking Screws, Self-Tapping Screws, Self-Drilling Screws, Coach Screws, Coach Bolts, Machine Screws and Security Screws.
Do you stock stainless steel self tapping screws?
We stock Stainless Steel Self-Tapping Screws and 3 grades of Stainless Steel Self-Drilling Screws.
Standard A2 Grade Stainless Steel Self-Drilling Screws for use in Aluminium profiles.
Hardened Grade 410 Stainless Steel Self Drilling Screws for use in mild steel and
Bimetallic Stainless Steel Self Drilling Screws which combine an A2 Stainless Steel Head and Thread with an Hardened Steel Drilling Point.
These give the corrosion resistance of A2 material with the ability to self-drill mild steel.
Can stainless steel screws be used outdoors?
Stainless Steel Screws are designed for applications where the screws come in to contact with water.
They are therefore ideal for external applications.
Are stainless steel screws heat resistant?
Stainless Steel Screws have good heat resistance with a melting point between 1400 and 1530 degrees Celsius depending on the alloy composition.
What are the benefits of stainless steel screws?
The main benefits of Stainless Steel Screws is their ability to resist corrosion, they offer much improved corrosion protection compared with Zinc plated screws.
They are used in many applications including outdoor projects such as Decking and Cladding applications, Kitchen Appliances, Automotive, Construction and Window applications.
