Belleville Compression Washers
• Essential when bolting aluminum lugs and connectors
to bus bars with steel or brass hardware
• Maintains constant pressure in heavy-duty,
high-temperature applications
• Available with or without flat washer
When bolting aluminum lugs and connectors to bus bars with steel or brass
hardware, the recommended practice to ensure a tight connection is to use
a Belleville spring washer on top of a flat washer under the bolt head or nut.
For heavy-duty service where the heat rise is expected to exceed 30° C above
ambient, this procedure maintains constant pressure as the connector metals
expand and contract with temperature changes.
Quick, dependable and versatile.

Note: Ordering quantity must be in unit quantities and multiples thereof.
The Belleville washer should be installed with a larger flat washer to spread the high
stresses of the spring washer edges over a large area of the lug and/or bus bar.
