Metallics JLW177 – Frequently Asked Questions
1) What bolt size do the Metallics JLW177 split lock washers fit?
The JLW177 is a 3/4 inch split lock washer, so it goes over 3/4 inch bolts, studs, and threaded rod. Buy it by the jar of 100.
2) Split lock washer or flat washer for a 3/4 inch bolted connection?
Different jobs. A flat washer spreads load and protects the surface; a split lock washer like the JLW177 is a spring ring that pushes back against the nut to resist loosening under vibration. On equipment mounts, strut, or machinery that shakes, the split lock is the one you want, and plenty of installers stack a flat washer under it for bearing.
3) Are the JLW177 washers okay for damp or outdoor electrical work?
They are steel with a zinc chromate finish, which gives light corrosion protection for indoor and sheltered use. For constant wet exposure, coastal air, or direct burial, step up to stainless.
4) Will a Metallics 3/4 split lock washer sit flat under a standard 3/4 hex nut?
Yes. The inside diameter is sized to 3/4 inch bolt, so it clears the threads and the outside diameter stays under the bearing face of a standard 3/4 inch hex nut or bolt head. If you are torquing against slotted strut or an oversized hole, add a flat washer beneath it so the split ring bears on solid metal.
5) What trades use these 3/4 inch split lock washers?
Metallics lists the JLW177 for the electrical, plumbing, heating and air conditioning trades. Typical use is hardware for hanging and bracing: threaded rod hangers, strut and channel assemblies, equipment anchors, and panel or transformer mounting where the joint sees vibration.
6) How many 3/4 split lock washers come in a jar of Metallics JLW177, and how heavy is it?
One hundred washers per jar, and the packed jar weighs 3.67 lbs. Jar dimensions are 5.75 x 3.5 x 3.5 inches, so it stores easily on a van shelf or in a job box.
