Metallics JBLW6 Washers No.6 Split Lock Sbr (Jar 100)

The JBLW6 is a No. 6 split lock washer, so it goes under No. 6 machine screws, sheet metal screws, and bolts. If you're working with No. 8 or No. 10 hardware, you need the corresponding No. 8 or No. 10 split lock washer instead, not this one.

Silicon bronze. That matters on jobs where plated steel would corrode or where you need to keep dissimilar-metal contact down, such as damp electrical enclosures, outdoor boxes, or bronze and copper grounding hardware. If you're fastening into plain steel in a dry interior, a zinc-plated steel split lock washer does the same mechanical job for less.

A split lock washer like the JBLW6 is a spring: the offset coil loads the joint and bites into the nut face and the surface under it, so the screw resists backing out under vibration. A flat washer only spreads the load and does nothing about loosening. On a No. 6 screw in a device box, panel, or equipment ground connection where vibration or thermal cycling is in play, the split lock is the one you want. Use both if you also need to protect a soft or slotted surface.

One hundred No. 6 split lock washers, packed in a jar rather than a loose bag. The jar is the practical part for a service van or a shop bench, you can pour out a handful and reseal it without the rest ending up in the bottom of a toolbox. Jar weight is listed at 0.1 lbs.

Both. Metallics lists the JBLW6 for electrical, plumbing, heating and air conditioning work. Silicon bronze holds up in the damp and mildly corrosive spots those trades run into, so the same jar covers panel and box screws, strap and hanger hardware, and equipment fastening.

It's a single-model item, part number JBLW6, so repeat orders come back identical every time, which is what you want for a stockroom bin. One jar covers 100 No. 6 fastener points in silicon bronze. For a facility running a mix of screw sizes, you'd pair it with the matching No. 8 and No. 10 split lock washers to cover the range.
