Metallics JG8LW175 – Frequently Asked Questions
1) What bolt size does the Metallics JG8LW175 split lock washer fit?
The JG8LW175 is a 1/2 inch split lock washer, so it goes under the nut or bolt head on 1/2 inch diameter threaded fasteners. Thread pitch doesn't matter for a lock washer, so it works with both 1/2-13 coarse and 1/2-20 fine threads.
2) Are these Grade 8 lock washers, and why does that matter for strut and heavy hanger work?
Yes, these are Grade 8 steel split lock washers in 1/2 inch. Grade 8 is the hardened class used with high strength bolting, so the washer won't flatten out and lose its spring tension under a Grade 8 bolt's clamp load. If you're assembling with lower grade hardware a Grade 8 washer is still fine, but pairing a soft washer with Grade 8 bolting is what causes loosening.
3) Is the finish on these 1/2 inch lock washers zinc plated, and is it suitable outdoors?
These are steel with a zinc plating. Zinc plate is a mild corrosion barrier meant for dry indoor and protected service, electrical rooms, interior strut runs, equipment mounting. For sustained exterior exposure, wet locations, or coastal air, step up to hot dip galvanized or stainless 1/2 inch lock washers instead.
4) Should I use a split lock washer or a flat washer with my 1/2 inch bolts?
They do different jobs. A split lock washer, which is what the JG8LW175 is, bites into the nut face and the joint to resist vibration loosening. A flat washer spreads clamp load over a larger area to protect soft or oversized material. On strut, channel, and equipment mounting it's common to use both: flat washer against the material, split lock under the nut.
5) Do these lock washers meet ANSI dimensional sizing?
The 1/2 inch Metallics split lock washer is built to ANSI sizing, so the inside diameter, outside diameter, and section thickness follow the standard regular series for a 1/2 inch washer. That matters if you're mixing stock from more than one supplier on the same job and need the washers to seat the same way under the nut.
6) Where is the Metallics JG8LW175 washer made?
Country of origin is China. If you're bidding public work with domestic sourcing requirements, that's the detail to check against your spec before you commit the fastener package.
