Premium A2 (304) Rust Protection
Using untreated or standard BZP steel outdoors guarantees premature rusting, which weakens the joint and ruins the look of your work.
A2 (also known as 304 grade) stainless steel contains a high percentage of chromium, which forms an invisible, self-healing oxide layer. This gives you the practical advantage of a fixing that fiercely resists rust, water damage, and atmospheric corrosion, making it perfect for permanent outdoor exposure.
Clean, Architectural Finish
When a washer rusts, it doesn't just fail it bleeds rust down the face of your building, staining expensive timber, brickwork, and painted surfaces.
Because A2 stainless steel does not oxidize and degrade in the rain, these washers maintain a clean, polished silver appearance indefinitely. This ensures your high-end landscaping, sign installations, and architectural fixtures continue to look highly professional long after the job is finished.
Essential Load Distribution
Driving a high-torque bolt directly into exterior timber or metal focuses all the pressure onto a very small area, which can easily crush the substrate.
Just like their BZP counterparts, these Form A washers instantly increase the bearing surface area. This evenly distributes the clamping force from the nut or bolt head, giving you a much stronger, more stable joint that won't bite into your materials under heavy wind or structural loads.
Standardized Form A Precision
Mismatched hardware can lead to uneven clamping and compromised structural safety.
Manufactured to exact DIN 125A specifications, these Form A washers feature a highly standardized thickness and outside diameter. This ensures a perfect, flush fit with standard metric stainless bolts and machine screws, guaranteeing reliable performance across all your heavy duty exterior assemblies.

Frequently Asked Questions
What is the difference between A2 and A4 stainless steel?
What is the difference between A2 and A4 stainless steel?
A2 (304) stainless steel is highly rust-resistant and perfect for almost all general outdoor and wet applications. A4 (316) stainless steel contains added molybdenum, making it "marine-grade" and resistant to extreme corrosives like saltwater, harsh industrial chemicals, and chlorine.
Can I use these A2 stainless washers with my standard BZP (zinc-plated) bolts?
Can I use these A2 stainless washers with my standard BZP (zinc-plated) bolts?
It is highly recommended not to. Mixing dissimilar metals (like stainless steel and zinc-plated steel) in an outdoor environment causes a reaction called galvanic corrosion. This will rapidly strip the zinc plating and cause the bolt to rust prematurely. Always pair stainless washers with stainless bolts and nuts.
Are these washers magnetic?
Are these washers magnetic?
A2 stainless steel is inherently non-magnetic. However, the manufacturing process (cold-working, stamping, and machining) can sometimes impart a very faint, trace magnetic signature to the finished washer. For completely non-magnetic requirements in highly sensitive environments, brass or nylon washers are preferred.
