Metallics JBWSS14 – Frequently Asked Questions
1) What does a Belleville conical washer actually do in an electrical connection?
A Belleville washer is a cone-shaped spring washer. Torquing the bolt flattens the cone, and the stored spring force keeps tension on the joint as the connection heats, cools, and the conductor or busbar relaxes. Metallics lists the JBWSS14 for load bearing tension type applications, which is exactly that job: maintaining clamping pressure on a bolted connection instead of just spreading load like a flat washer.
2) Can I use these 1/4 inch Belleville washers outdoors or in a damp location?
They are stainless steel, so corrosion resistance is good for outdoor enclosures, wet locations, and coastal or washdown environments where a plated carbon steel washer would rust and lose spring tension. Stainless also avoids the galvanic mismatch you get pairing plated steel with stainless bolts and nuts.
3) Which way does the Belleville washer face when I install it?
Crown up, against the nut or bolt head, with the outer rim seated flat on the work. Installed backwards the washer sits on its edge and you lose the spring action it is there to provide. Torque until the cone is flattened or nearly flat, per the connector or lug manufacturer's torque spec.
4) How many Belleville washers come in the Metallics JBWSS14 package?
The JBWSS14 ships 100 washers in a jar. For an MRO crib or a service truck that is a practical restock quantity, since these get consumed a few at a time on grounding lugs, busbar bolts, and strut connections rather than by the box.
