Metallics JBLW38D – Frequently Asked Questions
1) What size bolt does the Metallics JBLW38D split lock washer fit?
The JBLW38D is a 3/8 inch split lock washer, so it goes with 3/8 inch bolts, screws, and threaded rod. Match the nominal fastener diameter, not the wrench size across the nut.
2) Are these 3/8 lock washers bronze or plated steel?
Silicon bronze, not plated steel. That matters on grounding and bonding work and in damp or corrosive locations, where a plated steel washer rusts or sets up galvanic corrosion against copper and bronze hardware. If you are bolting to copper bus, bronze ground clamps, or bronze lugs, the bronze washer keeps the joint in similar metals.
3) How many 3/8 inch bronze split lock washers come in a jar?
100 pieces per jar. The jar pack is the sell unit, so one order gets you the full hundred rather than a loose count off a bin.
4) Can I use a bronze split lock washer on outdoor or underground grounding connections?
Silicon bronze is the usual choice for exposed and buried bonding hardware because it resists corrosion and matches the bronze and copper it is clamped against. The JBLW38D is a 3/8 inch silicon bronze split lock washer, which is why it shows up on ground rod clamps, bronze lugs, and pipe bonding rather than on dry interior steel framing.
5) Do I still need a flat washer if I use this 3/8 split lock washer?
On soft material, yes. The JBLW38D is a split lock washer only, so its job is anti-vibration, not load spreading. On aluminum, wood, or thin sheet, put a flat washer against the work surface and the split lock between the flat washer and the nut. On solid bronze or steel hardware the lock washer alone is normal practice.
6) Does a split lock washer go under the nut or under the bolt head?
Under the turning element, so under the nut if you are tightening the nut, under the head if you are tightening the bolt. The split spreads flat as you torque and the sharp ends bite the bearing surface to resist loosening from vibration. One 3/8 washer per joint, and do not stack two.
7) Is the Metallics JBLW38D washer made to a dimensional standard?
Yes, it is an ANSI dimensional washer, so the inside diameter, width, and thickness follow the standard 3/8 inch split lock pattern and it will seat properly under any standard 3/8 nut or bolt head.
8) Is there more than one version of the JBLW38D to choose from?
No options to specify. The JBLW38D ships one way: 3/8 inch, silicon bronze, split lock, 100 to the jar. Nothing to pick on finish or pack size.
