Metallics JLWX7SB – Frequently Asked Questions
1) What size bolt does the Metallics JLWX7SB external tooth lock washer fit?
The JLWX7SB is a 5/16 inch external tooth lock washer, so it goes over 5/16 inch bolts, screws, and threaded studs. Match the washer size to the fastener diameter, not to the nut's wrench size.
2) Is the Metallics JLWX7SB washer suitable for outdoor or marine grounding connections?
It's made of silicon bronze, which is the material commonly specified for corrosion resistance in wet, outdoor, and marine environments, and it's an electrical-department fastener. That makes it a reasonable pick for exterior grounding and bonding hardware where plated steel would rust.
3) What's the difference between an external tooth lock washer and a split lock washer?
An external tooth washer like the 5/16 JLWX7SB has teeth around the outer edge that bite into both the bolt head or nut face and the mounting surface, spreading the anti-rotation grip over a wide circle. A split ring washer concentrates its spring force at one gap. External tooth is the usual choice under a wide bearing surface and where you want the teeth to scrape through coating for an electrical bond; split rings are more common in general mechanical assembly.
4) How many washers come in a jar of Metallics JLWX7SB?
100 washers per jar. The jar pack is useful on a service truck or shop bench, since the washers stay contained and the 5/16 size stays separated from other diameters.
5) Can I use a silicon bronze lock washer with stainless or galvanized hardware?
Bronze against stainless or galvanized is a dissimilar-metal pairing, so in wet exterior locations you can get galvanic corrosion at the joint. The cleanest practice is to keep the JLWX7SB with bronze or brass bolts and nuts, which is how silicon bronze fasteners are normally specified as a matched set.
6) What part number should I give my distributor for Metallics 5/16 external tooth bronze lock washers?
Order by Metallics MPN JLWX7SB. That number covers the 5/16 external tooth silicon bronze lock washer in the 100-count jar.
7) How much does a jar of 100 Metallics 5/16 bronze lock washers weigh and how big is the container?
The jar weighs 0.16 lbs and measures 3 x 2.15 x 3 inches. Small enough to keep several sizes in one bin drawer or a truck stock tray.
