Metallics JG8SW76 – Frequently Asked Questions
1) What bolt size do the Metallics JG8SW76 flat washers fit?
They're 1/2 inch SAE flat washers, so they pair with 1/2 inch diameter bolts and threaded rod. SAE pattern means a smaller outside diameter and smaller hole than a USS washer of the same nominal size, so it bears tighter against the bolt head or nut rather than spreading load over a wide area.
2) Are these Grade 8 washers hardened, and does that matter for my connection?
Yes, the JG8SW76 is a Grade 8 washer in steel with a zinc finish. Grade 8 flat washers are through-hardened, which is what you want under a Grade 8 bolt or nut being torqued high, a soft washer will dish or embed and you lose clamp load. If you're only fastening a strut clamp or a light bracket with a Grade 2 or Grade 5 bolt, a standard flat washer will do the job.
3) Can I use these zinc plated washers outdoors or in a wet location?
Zinc plated steel is a dry to mildly damp finish. It holds up fine indoors, in panels, in mechanical rooms and inside enclosures, but in direct weather, washdown areas or near salt it will rust at the edges over time. For exterior and corrosive work, spec a hot dip galvanized or 18-8 stainless 1/2 inch flat washer instead.
4) Will a 1/2 inch SAE washer sit on standard strut or a 9/16 inch punched hole?
It covers a standard 9/16 inch clearance hole for a 1/2 inch bolt, which is the usual punch in strut, angle and equipment feet. On wide slotted strut or oversized holes in sheet metal the SAE outside diameter is small and may pull through the slot, use a USS or a strut washer there instead.
5) How many washers come in a jar of Metallics JG8SW76?
100 washers per jar, packed in a jar rather than a box or bag. The jar runs 3 x 3 x 2.7 inches and weighs 1.6 lbs filled, so it sits on a van shelf or in a gang box drawer without spilling like a poly bag does.
