ZINC FLAT WASHERS HANDY PACK

Zinc flat washers are primarily used to distribute the clamping load of a bolt or nut over a larger surface area, which prevents the fastener from digging into or damaging the material. The zinc plating provides a layer of corrosion resistance, making them ideal for indoor projects or areas with light moisture.

Primary Functions
Load Distribution: They spread the pressure of a tightened nut or bolt head, which is essential when working with soft materials like wood, plastic, or thin sheet metal that might otherwise crush or deform.
Surface Protection: They act as a smooth barrier to prevent the rotating fastener from scratching or marring the finished surface of your project.
Spacing and Alignment: Handy packs often serve as spacers to fill gaps if a bolt is slightly too long, or to provide a flat bearing surface on uneven or oversized holes.
Preventing Galvanic Corrosion: They can act as an insulating layer between different metals (e.g., steel screws on aluminium surfaces) to prevent rapid corrosion. 

Common Applications
Automotive: Used in vehicle assemblies to secure components and protect painted or finished surfaces from vibration-induced wear.
Construction & DIY: Essential for timber framing, steel fabrication, and household repairs where reliable fastening is needed.
Machinery: Frequently used in mechanical assemblies to maintain clamping force and protect internal parts from damage during maintenance.
Household Appliances: Found in white goods and electronics to secure components while resisting the moisture often found in kitchens or laundries.
