Washers Flat BS Zinc M3 – M30 (Packs of 100)
R2,30
Applications
Flat washers distribute the load of a threaded fastener—like a bolt or screw—preventing surface damage and ensuring a bigger bearing surface. The zinc plating acts as a sacrificial protective layer, reducing the risk of corrosion in basic environmental conditions. These washers are ideal for machinery, fabrication, and general fastening needs.
