Minerallac 70525J – Frequently Asked Questions

1) Can I use these split lock washers outdoors or in a coastal/marine installation?
Type 18-8 stainless steel is what these Minerallac split lock washers are made from, and the stated applications include marine and coastal work, outdoor infrastructure, and chemical processing facilities. The finish is bare stainless (silver), so there is no plating to wear off and start rusting at the split edge the way a zinc-plated steel washer does.
2) What sizes do Minerallac stainless split lock washers come in?
Four sizes: #10 (70515J), 1/4 inch (70525J), 3/8 inch (70535J), and 1/2 inch (70540J). Order by bolt diameter, not by washer OD. All are Type 18-8 stainless, supplied in jars of 100.
3) Do I need a split lock washer or a flat washer for an electrical panel or strut connection?
They do different jobs. A flat washer spreads load over a wider bearing area and protects soft material. A split lock washer, like this medium-split Minerallac, is there to resist loosening from vibration by holding spring tension on the fastener. On equipment that shakes, HVAC units, motors, industrial assemblies, panel mounting, you want the lock washer; if your concern is pull-through on sheet metal, add a flat washer under it.
4) Will these stainless washers be a problem bolted to galvanized or plated steel?
Mixing metals matters here. Type 18-8 stainless against zinc-plated or galvanized steel puts two dissimilar metals in contact, and in wet or coastal service the less noble coating corrodes first. For outdoor and marine jobs the cleaner approach is to keep the whole fastener stack, bolt, nut, flat washer and this split lock washer, in 18-8 stainless.
5) How many washers come in a jar, and is the jar packaging practical for a service truck?
Each jar holds 100 washers. The jar format keeps one size separated and sealed, which is the point on a truck or in a shop crib where loose split washers in a bin get mixed between #10, 1/4, 3/8 and 1/2.
6) Are these washers food-grade or suitable for food processing equipment?
Food processing equipment is one of the stated applications for these Minerallac split lock washers, on the basis of Type 18-8 stainless construction and a bare stainless finish with no plating to flake. If your facility requires a specific sanitary certification on fasteners, that is a separate qualification from the material itself.
