Metallics SBW34 – Frequently Asked Questions
1) What size bolt does the Metallics SBW34 flat washer fit?
The SBW34 is a 3/4 inch flat washer, so it is sized for 3/4 inch bolts, rods, or studs. For grounding and bonding hardware, that is the common size under 3/4 inch threaded rod and large lug bolts.
2) Is the Metallics SBW34 washer silicon bronze or plated steel?
Silicon bronze, solid, not a plating. That is why it gets specified for grounding connections and outdoor or damp locations where a plated steel washer would corrode and lose contact.
3) Can I use a silicon bronze flat washer with copper grounding lugs and conductors?
Yes. The SBW34 is silicon bronze, which is a copper alloy, so pairing it with copper lugs, busbars, and ground rod clamps keeps the connection to similar metals and avoids the galvanic mismatch you get when steel washers are used on copper grounding hardware.
4) Do I need a lock washer too, or is the flat washer enough?
The SBW34 is a flat washer only. It spreads load and protects the surface under the nut; it does not provide any locking action. If the connection is subject to vibration, order a separate lock washer or locknut alongside it.
5) Is the Metallics SBW34 washer made to a standard dimensional spec?
It is an ANSI dimensional washer, so the inside and outside diameter and thickness follow the standard 3/4 flat washer pattern rather than a proprietary one. That matters when you are mixing it with hardware already on the job.
6) How many Metallics SBW34 washers come in a box?
They ship 100 to a box. For an electrical contractor stocking a truck or a facility crib, that is one carton per size rather than loose-count bagging.
