Simple penny washer. Made from grade 304 (A2) stainless steel for good corrosion resistance. Supplied in boxes of 100pcs.

Grade A2 stainless steel is far more corrosive resistant than if the washer was manufactured using mild steel. This is due to the added chromium in the stainless steel. Another key factor to why stainless steel is used to manufacture this product is because of it's very good resistance to wear and tear.

Penny washers are the most common kind that you're likely to come across and they generally serve three distinct purposes:

• The distribution of nut/bolt pressure evenly over the part to be secured, reducing the chance of it being damaged

• The provision of a smooth, level surface for the nut/bolt to bear upon, reducing the likelihood of loosening due to uneven fastening surfaces

• Creating an effective seal against water ingress (these are then known as plumbing washers)

Two other purposes that washers are used for, though this is not a proper usage and can be dangerous to health and/or damaging to property, are:

• To permit bolts/nuts of insufficient size to be used in the holes of a secured part

• To facilitate the tightening of a nut/bolt that is too long for the job
