Metallics JBW12 – Frequently Asked Questions
1) What size bolt does the Metallics JBW12 Belleville washer go with?
The JBW12 is a 1/2 inch Belleville washer, so it pairs with 1/2 inch bolts and threaded rod. It's a zinc plated steel conical spring washer, sold 100 to a jar.
2) Why use a Belleville washer instead of a flat washer on an electrical connection?
A Belleville washer is a cone shaped spring washer. It flattens as the bolt is torqued and keeps pressure on the joint as the conductor and hardware expand and contract with load cycling, which is why they show up on bus bar, ground connections and lug terminations where a plain flat washer would let the joint loosen over time. The JBW12 is the 1/2 inch size of that washer in zinc plated steel.
3) Is the Metallics JBW12 washer okay for outdoor or damp locations?
It's zinc plated steel. Zinc plating handles indoor and normally dry or occasionally damp conditions fine, but it isn't stainless. For continuous wet, coastal or corrosive environments, spec a stainless or hot dip galvanized fastener instead.
4) Which way does a Belleville washer face when I install it?
Crown up, against the bolt head or nut, with the outer rim bearing on the joint surface. It should be torqued until it flattens out. The JBW12 is the 1/2 inch size, so it goes under a 1/2 inch head or nut.
5) How many Metallics JBW12 washers come in a jar?
100 pieces per jar. The jar pack is the ordering unit, which suits a service truck or an MRO crib where you're pulling a handful at a time rather than a bulk box.
