Metallics JSSW17 – Frequently Asked Questions
1) What bolt size does the Metallics JSSW17 flat washer fit?
The JSSW17 is a 5/8 inch flat washer, so it suits 5/8 inch bolts, screws and threaded rod. The inside diameter runs 21/32 inch, which gives the small clearance over a 5/8 inch shank you want for the washer to seat flat rather than bind on the threads.
2) Are these 5/8 washers stainless steel or plated?
Stainless steel through, not a plated carbon steel washer. That matters on exterior strut, rooftop equipment supports and damp vaults, where a zinc plated washer gives up first and leaves a rust streak down the member. Pair them with stainless bolts and nuts so you are not mixing metals in the joint.
3) How many washers come in a jar of Metallics JSSW17?
One hundred per jar, packed as a jar rather than a loose bag, so it stays closed on the truck and on the cart. Jar weight is about 2 lbs. For shops stocking a van, a jar is the practical buy unit for 5/8 bolting work.
4) Can I use a flat washer like this instead of a lock washer under a nut?
Different jobs. A flat washer spreads the clamp load over a wider bearing area and protects the surface under the nut or bolt head; it does nothing to resist loosening from vibration. On equipment that vibrates, use a flat washer against the material and add a split lock washer or a locknut above it. The JSSW17 is specifically a flat washer in 5/8 size.
5) Is this washer meant for metal-to-metal connections or for bolting through wood?
It is specified for metal to metal work, which is where most 5/8 electrical and MRO bolting lands: strut and channel, equipment frames, transformer pads, generator and rooftop unit anchorage. Bolting through wood or into soft material generally wants a larger diameter bearing washer to keep the head from crushing in.
