Metallics LW1745M – Frequently Asked Questions
1) What bolt size does the Metallics LW1745M split lock washer fit?
The LW1745M is a 3/8 inch split lock washer, so it sizes to 3/8-16 threaded bolts, screws, and rod. It is sold by the model number LW1745M.
2) How many washers come in a box of Metallics LW1745M?
One box holds 5,000 pieces of the 3/8 split lock washer. The pack type is a box, and the shipping unit weighs 30.86 lbs with carton dimensions of 9 x 9 x 6.13 inches. That is a bulk MRO or jobsite quantity, not a small hardware pack.
3) Will the LW1745M work with 3/8 inch threaded rod hangers?
Yes. It is a 3/8 size split lock washer, so it drops over 3/8 inch all-thread rod and seats under a 3/8 nut on trapeze hangers, strut clamps, and conduit supports.
4) Are these 3/8 lock washers OK for damp or outdoor electrical work?
Material is zinc plated steel. The zinc gives moderate corrosion protection for dry indoor and sheltered locations, which is what plated steel hardware is normally specified for. For continuously wet, outdoor exposed, or washdown locations, specify a stainless steel 3/8 split lock washer instead.
5) Split lock washer or flat washer for strut and electrical mounting?
Different jobs. The LW1745M is a split lock washer, so its sprung helical form bites into the nut and the mounting surface to resist loosening from vibration, which is what you want under a nut on conduit clamps, strut fittings, or equipment mounts. A flat washer spreads load and protects the surface but does nothing against vibration. On soft or slotted material, many installers use both: flat washer against the surface, split lock under the nut.
6) Is the 3/8 split lock washer built to a standard size?
Dimensional sizing follows ANSI, so the 3/8 washer's inside diameter, width, and thickness match the standard 3/8 regular-series split lock washer footprint. It will interchange with other ANSI-dimensioned 3/8 split lock washers already on your racks.
7) Where are Metallics LW1745M lock washers made?
Country of origin is China. That matters if you are bidding work with domestic-sourcing requirements, so check the spec on the project before committing to this box.
