Metallics JLWX8SB – Frequently Asked Questions
1) What size bolt does the Metallics JLWX8SB external tooth lock washer fit?
The JLWX8SB is a 3/8 inch external tooth lock washer, so it seats under a 3/8 inch bolt head or nut. External tooth means the serrations ring the outside diameter, which is what you want where the bearing surface is wide enough to let the teeth bite the mating part rather than the shank.
2) Is a silicon bronze lock washer OK for outdoor or corrosive electrical work?
Silicon bronze is the material here, and that is the reason electricians reach for this washer instead of plain steel: it resists corrosion in damp, coastal, and buried or wastewater environments, and it pairs with bronze or copper grounding hardware without setting up the galvanic couple you get from mixing dissimilar metals.
3) Can I use the JLWX8SB as a bonding or grounding washer?
That is the normal use for an external tooth bronze washer. The teeth cut through paint, galvanizing, or oxide on an enclosure or strut surface and bite into the base metal, establishing metal-to-metal contact between a 3/8 inch bonding bolt and the part it is grounding. The silicon bronze keeps that contact from corroding away.
4) How many washers come in a jar of Metallics JLWX8SB?
100 pieces per jar. The jar pack is the usual MRO and service-truck quantity: it keeps the washers together on a shelf or in a bin and the whole container weighs 0.18 lbs.
5) External tooth or internal tooth lock washer, which should I use on a 3/8 bolt?
External tooth, which is what the JLWX8SB is, puts the serrations on the outer diameter so they grip under a wide flange, hex head, or nut face and give more locking leverage. Internal tooth hides the teeth inside the outer edge and is the choice when the fastener head is small or when you do not want teeth marring a visible finish. For a 3/8 bonding or strut connection where you want the washer to score through coating, external tooth is the one.
6) Will these bronze washers work with stainless or galvanized steel bolts?
Bronze against galvanized steel is a mismatch worth avoiding in wet locations, since zinc will sacrifice to the bronze. Silicon bronze runs well alongside stainless, copper, and other bronze hardware. If your 3/8 bolt is galvanized and the joint stays wet, use a matching galvanized or stainless washer instead of the JLWX8SB.
7) What size container does the Metallics JLWX8SB jar take up in a van bin?
The jar measures 3 x 3 x 2.15 inches as listed, so it drops into a standard small parts bin or tray without repacking.
