Where to get them: McMaster-Carr (http://www.mcmaster.com/#91081a046)
Product #: 91081A046
Amount to buy: 6
Cost: $11.10 Total + Shipping ($1.85/ea)
That is a FRACTION (pun intended) of the price if you buy the commercial type of Fractional Plates! They also fit perfectly on 2″ Olympic Barbells!
Below is what the washers look like:
McMaster-Carr Washer Dimensions
Fact: McMaster-Carr Washers DO NOT come in uniform thickness (as shown above) so their weight can vary slightly.
The 6 washers I bought have the following weights
- 0.60 lbs
- 0.616 lbs x 2
- 0.622 lbs x 2
- 0.642 lbs
Here’s how the poundages work out:
1 washer PER SIDE= 1.25 total pounds
2 washers PER SIDE= 2.5 total pounds
3 washers PER SIDE= 3.75 total pounds
4 washers PER SIDE= 5 pounds
That is why you only need 6 washers total.
