Metallics JLW175 – Frequently Asked Questions

1) Will a zinc chromate steel lock washer hold up in a damp mechanical room or outdoors?
The JLW175 is plain steel with a zinc chromate finish, which is a sacrificial coating meant for general corrosion resistance indoors and in protected exterior conditions. It is the right pick for electrical enclosures, HVAC equipment mounting, and pipe supports. For continuous wet exposure, coastal air, or direct ground contact, a stainless or hot dip galvanized lock washer is the better call, since zinc chromate will eventually bloom white and then rust.
2) How many 1/2 inch split lock washers come in a jar of the Metallics JLW175?
They ship 100 to a jar. The jar measures 3 x 3 x 2.7 inches and the packed weight is 1.315 lbs, so it stores easily in a van bin or a parts drawer without decanting.
3) Split lock washer or flat washer with a nylon insert nut, which should I use on vibrating equipment?
A split lock washer like the JLW175 works by digging its cut ends into the nut face and the joint surface while the spring keeps tension on the fastener, so it resists loosening from vibration and thermal cycling and it can be reused within reason. A nylon insert lock nut grips the thread instead and holds better at low clamp loads, but it is single use and is not rated for high heat. On electrical panel hardware, bus bar connections, and duct and equipment mounting, the split lock is the conventional choice. If you also need to spread load over sheet metal or an oversized hole, add a flat washer under the lock washer.
4) Which way does the split lock washer go on, and does it go under the bolt head or the nut?
Put it against whichever element you are turning, bolt head or nut, and directly against the clamped surface so the two cut ends can bite. The gap faces away from the surface as you start, and the washer flattens out as you torque down. If it is still visibly open at final torque, you are under-torqued. Never stack two of them to get more grip, and do not run one directly against soft aluminum or a painted panel without a flat washer underneath.
5) Can I use these steel lock washers on an electrical grounding or bonding connection?
The JLW175 is a plain steel washer with a zinc chromate finish, sold for electrical, plumbing, and HVAC work, and it is commonly used on panel hardware and bus bar mounting. Note that a split lock washer is a locking device, not a listed bonding component, and steel against copper or aluminum in a damp location will set up galvanic corrosion. For a ground bond, use the listed lug or bonding washer the equipment calls for and keep this washer for the mechanical fastening.
