Flat washers are used with threaded fasteners for distributing the load uniformly and reducing frictional losses during screw tightening. These units are used for providing spacing and electrical insulation in control boxes. Raptor Supplies offers a wide array of flat washers from Accurate Mfd Products, Apollo, Armor Coat, C. Sherman Johnson, Dynaform, Earnest, Fabory, Foreverbolt, Grainger, Master Products, Metric Blue, TE-CO and Micro Plastics.
Lighter than stainless steel and imparts non-magnetic properties
Provides resistance to tearing, flexing, puncture, wet & dry abrasion, fire, fungi and chemical attack
Highly elastic & vibration-absorbant
Lightweight & cheaper to use than other materials; offers superior insulation and low thermal conductivity
Provides water, stain, mold & mildew resistance; durable and antimicrobial
Provides corrosion (especially seawater) & metal fatigue resistance; better conductivity than most steel variants
Features low ductility, good dimensional stability and wear resistance
Offers greater corrosion resistance but lesser hardness, as compared to steel
High electrical conductivity, heat conductivity and corrosion resistance
Offers structural rigidity, strength, hardness & durability
Provides corrosion resistance and low friction
Corrosion-resistant and moderate structural rigidity
Greater strength-to-weight ratio and rigidity at the same thickness as plastic
Provides better corrosion resistance than zinc plating, owing to thick coating
Provides a similar look as the fastener surface
For corrosion resistance & yellow-coloured finish
Lesser corrosion resistance, but better adhesion properties than zinc plating; suitable for dry environments
Provides high resistance to saltwater corrosion
Mild to high corrosion resistance in wet environments
Resists chemicals and can withstand 1000 hours of salt spray
Greater protection against corrosion than black zinc plating
Light to medium corrosion resistance; minimises light reflection
Stops corrosion, retains electrical conductivity and provide an appealing finish
Offers superior corrosion resistance, ductility and solderability
For easy distinguishing & identification
Increases corrosion resistance of stainless steel screws by removing free iron & creating a protective oxide layer
Adds brightness, lustre and appeal; provides corrosion and wear resistance
Better corrosion resistance and forming properties as compared to traditional zinc coating
