Metallics JWWHH84 – Frequently Asked Questions
1) What bolt size does the Metallics JWWHH84 flat washer fit?
The JWWHH84 is a 5/8 inch USS pattern flat washer, so it is sized for 5/8 inch bolts, anchors, and threaded rod. USS pattern means a wider outside diameter and larger clearance hole than an SAE washer of the same nominal size, which is what you want when you are spreading load against a softer surface or a slightly oversized hole.
2) What does extra heavy mean on a 5/8 USS flat washer, and when should I use one instead of a standard washer?
Extra heavy refers to thickness: the JWWHH84 is a thicker steel washer than a standard 5/8 USS flat washer. Use it where the washer is carrying real bearing load and you do not want it to dish or cup, such as under a nut on strut, channel, or beam clamps, or anchoring equipment and supports to concrete. For light clamping on sheet metal or inside an enclosure, a standard thickness washer is enough.
3) Is the Metallics JWWHH84 washer plain steel or stainless?
It is a steel washer, not stainless. For wet, exterior, or corrosive locations you should be specifying stainless or a hot dip galvanized washer instead; plain steel is intended for dry interior work.
4) How many 5/8 USS extra heavy washers come in a pack of Metallics JWWHH84?
Fifty pieces per pack. That is a working quantity for a single hanger or support run, so if you are standardizing on 5/8 rod across a job, order by the number of bearing points plus spares rather than by the box.
