Metallics JMLW012 – Frequently Asked Questions
1) What bolt size does the Metallics JMLW012 split lock washer fit?
It's a metric lock washer sized for M12 bolts and screws. If you're working with imperial hardware, M12 is not an interchangeable substitute for a 1/2 inch washer even though the two are close, so match the washer to the thread standard of the bolt you're using.
2) How many M12 split lock washers come in the Metallics JMLW012 jar?
100 washers per jar, supplied in a jar rather than a box or bag, so it works as a bench or service-truck stock item you draw from as you go.
3) Are these zinc plated steel washers OK for outdoor or damp electrical work?
The JMLW012 is steel with a zinc finish, which is a general-purpose plating suited to dry indoor and protected locations. For sustained outdoor exposure, washdown areas or corrosive environments, spec a stainless or hot-dip galvanized lock washer instead.
4) What is a split lock washer used for on an electrical installation?
A split lock washer goes under the nut and its sprung, offset ends bite into the nut and the mating surface as it's torqued, resisting loosening from vibration. Metallics lists the JMLW012 for electrical, plumbing, heating and air conditioning work, so typical uses are strut and channel hardware, panel and enclosure mounting, and equipment anchoring where an M12 bolt is in play.
5) Do I still need a flat washer if I use the JMLW012 split lock washer?
The JMLW012 is a lock washer only, not a flat washer, and the jar of 100 contains nothing else. On soft or slotted materials most installers put a flat washer against the surface with the split lock washer between it and the nut, so order flat washers separately if the job calls for them.
6) How much does a jar of 100 Metallics M12 lock washers weigh and what size container is it?
The jar comes in at 0.92 lbs and measures 3 x 3 x 2.7 inches, small enough to sit in a van drawer or a parts bin without repacking.
7) Is the Metallics JMLW012 part number the one to order for M12 metric lock washers?
Yes, JMLW012 is the Metallics manufacturer part number for the M12 split lock washer in steel with zinc finish, sold 100 to a jar. That's the single ordering designation; there are no finish or size options under it.
