Metallics JG8SW78 – Frequently Asked Questions
1) What bolt size do these 3/4 inch SAE flat washers go with?
The JG8SW78 is a 3/4 inch SAE pattern flat washer, so it pairs with 3/4 inch diameter bolts and threaded rod. SAE pattern means a smaller outside diameter and narrower bearing surface than a USS washer of the same bolt size, so if your drawing calls for the wider USS pattern, this is not the right washer.
2) Are the Metallics JG8SW78 washers hardened, or just standard mild steel?
These are Grade 8 steel washers, zinc plated. Grade 8 is the hardened class used under Grade 8 bolts and high-strength structural connections, where a soft washer would dish out under the clamp load. For light-duty strut and box mounting a standard flat washer is enough; spec these where the bolt itself is high strength.
3) How many washers come in the Metallics JG8SW78 jar?
Each JG8SW78 jar holds 100 of the 3/4 inch flat SAE washers. The packed jar weighs 4.27 lbs, so it is easy to keep one on a service truck or in a job box without breaking down a bulk carton.
4) Can I use these zinc plated washers outdoors or in a wet location?
Zinc plating gives moderate corrosion resistance, which covers dry indoor electrical rooms, covered mechanical spaces, and short-term exposure during construction. For permanent outdoor, coastal, or wash-down service, hot-dip galvanized or stainless washers hold up better. The JG8SW78 is a zinc plated steel washer, not stainless.
5) Is the JG8SW78 washer made to a recognized dimensional standard?
It is an ANSI dimensional-standard washer in the SAE 3/4 inch pattern, which matters when a submittal or MRO spec calls for standard-pattern hardware rather than a proprietary shape.
6) How much shelf or bin space does a jar of JG8SW78 washers take up?
The jar measures 3.5 in by 3.5 in with a height of 5.75 in, so it fits a standard parts-bin shelf or a van drawer upright. Useful if you are standardizing fastener stock across a shop and want a consistent footprint.
