Applications & Selection Guide
Carbon-steel Form A flat washers to DIN 125 / ISO 7089. A plain annular disc that spreads clamp load under a bolt head or nut and protects the bearing surface. Metric sizes for M3–M60 assemblies are listed above.
The default washer for general metric joints with DIN 933/931 bolts and DIN 934 nuts. Form A is the standard small-OD pattern; oversized or structural plate washers (DIN 7989) are a different product for slotted holes and steelwork. Hardened washers may be required under high-preload 8.8/10.9 heads — say so in the enquiry if the joint specification calls for them. Zinc or HDG can be quoted for outdoor service.
Choose the matching metric bolt size above. Add quantity, coating, and destination; bolts and nuts can go in the same quote cart.
