Metallics JLWX8M – Frequently Asked Questions
1) What bolt size do the Metallics JLWX8M external tooth lock washers fit?
The JLWX8M is a 3/8 inch external tooth lock washer, so it is sized for 3/8 inch bolts, screws, and threaded rod. The teeth sit on the outside diameter and bite into the bearing surface and the nut or screw head to resist loosening under vibration.
2) Are external tooth lock washers the right choice for bonding and grounding connections?
External tooth washers are the style commonly used where you want the teeth to cut through zinc plating, paint, or enclosure coating to make metal-to-metal contact, which is why they turn up on grounding lugs and panel bonding work. The JLWX8M is a steel washer with zinc plating, an electrical-department fastener. For a specifically listed grounding washer, use a part marked for that purpose; this one is a general-purpose 3/8 external tooth lock washer.
3) Will zinc plated steel lock washers hold up outdoors or in a damp location?
The JLWX8M washers are zinc plated steel. Zinc plating is a mild corrosion barrier suited to indoor and dry or protected locations. For wet, coastal, or chemically aggressive exposure, specify stainless steel instead; plated steel will eventually show red rust once the teeth scrape through the plating at the contact points.
4) Should I use an external tooth lock washer or a split ring lock washer on a 3/8 bolt?
External tooth, like the JLWX8M, spreads its grip around a wide circle of teeth and resists rotation better on sheet metal, enclosure covers, and strut connections where the bearing surface is thin. A split ring concentrates its bite at two points and is more common under a nut on heavier structural steel. If you are fastening into a painted or plated surface and want the washer to break through the coating, external tooth is the one to reach for.
5) What is the Metallics part number for the 3/8 inch external tooth lock washer in a 1000 count jar?
Order Metallics JLWX8M. That number covers the 3/8 inch external tooth lock washer, zinc plated steel, 1000 pieces per jar.
