Product Description
The DIN9021B-6.4-A2 is a large-diameter stainless steel washer conforming to DIN 9021 specifications for M6 fasteners. This cupped washer spreads clamp load across a wider bearing surface, preventing bolt pull-through in oversized or soft holes common in aircraft panel and bracket assemblies. The A2 stainless material resists corrosion in aviation environments.
Install beneath bolt heads or nuts to provide smooth load distribution and maintain structural integrity during assembly and vibration cycles.
