What Stainless Steel Bolts are Used for
Stainless steel bolts are used wherever a strong fixing is required, particularly in environments where long-term corrosion resistance matters. Typical applications include:
- Steel fabrication and general engineering
- Timber construction and landscaping
- Building services and HVAC installations
- Outdoor structures, fencing, and street furniture
- Marine, coastal, and food-related environments
Compared to plated carbon steel fixings, stainless steel bolts offer long-term resistance to rust without the need for coatings, making them suitable for exposed and demanding conditions.
Standards and Materials
Our stainless steel bolts are manufactured to recognised international standards such as DIN and ISO, ensuring compatibility with standard nuts, washers, and tools.
Most Fixabolt bolt ranges are supplied in:
- A2 stainless steel – suitable for general-purpose use, indoor and outdoor environments.
- A4 stainless steel – higher corrosion resistance, commonly specified for marine, coastal, and chemical exposure.
Exact strength values and dimensional tolerances depend on the specific bolt type and standard. Full details are provided on each individual bolt collection and product page.
How to choose the right stainless steel bolt
When selecting a bolt, consider the following:
- Bolt type – hex bolts, set screws (full thread bolts DIN 933), coach bolts, or structural fixings depending on the application.
- Diameter and length – chosen to suit the load and thickness of the materials being fixed.
- Thread type – fully threaded or partially threaded depending on clamping requirements.
- Material grade – A2 for general use, A4 for harsher environments.
If you are unsure, start by selecting the bolt type closest to your application, then refine by size and grade within that collection.

FAQs
What are stainless steel bolts used for?
Stainless steel bolts are used for mechanical fixing where strength, durability, and corrosion resistance are required. They are common in construction, engineering, outdoor installations, and marine environments.
What is the difference between A2 and A4 stainless steel bolts?
A2 stainless steel bolts are suitable for most general applications. A4 stainless steel bolts offer increased resistance to corrosion and are typically specified for marine or chemically exposed environments. If you need A4, we can supply them at quantities of 50+ without any standard delivery lead time delays. Please get in touch on our live chat if you would like a quote for A4 bolts.
Can I bulk buy stainless steel bolts?
Yes. Fixabolt supplies stainless steel bolts in trade-friendly quantities, making bulk buying straightforward for ongoing projects and maintenance work.
How do I choose the correct bolt type?
Start with the application. Timber fixings often use coach bolts, steel assemblies commonly use hex bolts or set screws, and masonry fixings may require through bolts. Each bolt collection provides guidance on typical use cases.
