The Unifix A2-304 Stainless Steel Form A Flat Washers are essential components for hobbyists, contractors, and DIY enthusiasts who require secure, corrosion-resistant fastening for M6 hardware. These washers excel in distributing load pressure across surfaces to prevent damage, though they are specifically engineered for M6 fasteners and will not fit larger or smaller bolt diameters. They serve as a reliable choice for long-term structural integrity in diverse environments.

DIN 125 is a German industrial standard that defines the dimensions and tolerances for flat washers, ensuring they meet specific mechanical requirements.
Yes, the A2-304 stainless steel provides high corrosion resistance, making them suitable for many outdoor and light marine applications.
The washers have an inner diameter of 6.4 mm, designed specifically for M6 fasteners.
No, they are exclusively designed for M6 hardware.
Each box contains 250 pieces.
While A2-304 stainless steel is highly resistant to corrosion, it is not immune to oxidation in extremely harsh chemical environments or prolonged exposure to strong acids.
Verify that your bolt is indeed an M6 size; if the bolt diameter is larger than 6 mm, the washer will not fit.
Ensure that the surface being fastened is flat and clean; excessive debris can prevent the washer from seating correctly.
To ensure proper installation, simply slide the washer onto the shank of your M6 bolt before threading it into the nut or receiving material. No specific maintenance is required, though you should inspect connections periodically if exposed to harsh, acidic, or saltwater environments to ensure no debris has accumulated. Store the box in a dry area to keep the washers clean and free from surface contaminants before use. Ensure you are using the correct M6-sized fasteners, as the 6.4 mm inner diameter will not accommodate M8 or M10 hardware.
