Metallics JSWC73 – Frequently Asked Questions
1) Is the Metallics JSWC73 washer solid copper, and why would an electrician want copper instead of steel?
JSWC73 is a 1/4 inch flat washer made of copper. Electricians reach for copper washers on grounding and bonding connections because keeping the washer the same metal as a copper conductor or copper bus avoids the dissimilar-metal galvanic corrosion you get when steel or zinc-plated hardware sits against copper in a damp location.
2) What bolt size does the JSWC73 copper flat washer fit?
It is sized for 1/4 inch hardware, so it seats under a 1/4-20 bolt head or nut, or on a 1/4 inch ground stud or lug screw.
3) How many copper washers come in a jar of Metallics JSWC73?
Each jar holds 100 washers. Metallics packs this one in a jar rather than a bag, which is the handier format for a van bin or a bench drawer where you are pulling a few at a time.
4) Is a flat washer like the JSWC73 the right choice, or do I need a lock washer?
A flat washer spreads the load of the bolt head or nut over a wider area and protects the surface underneath; it does nothing to resist loosening. If the joint sees vibration and you need the fastener to stay tight, use a split or tooth lock washer in addition, with the flat washer against the softer surface. On a grounding connection where corrosion is the concern, the copper flat washer is the part doing that job.
