Metallics JBLW516 – Frequently Asked Questions
1) Is the Metallics JBLW516 lock washer steel or bronze?
Silicon bronze, not plated steel. That matters where the connection sees moisture, outdoor exposure or dissimilar-metal contact: bronze hardware holds up in damp and coastal conditions and pairs with bronze or copper components without the galvanic problems you get mixing steel into a copper assembly. It is a common choice on grounding and bonding work and marine-adjacent installs.
2) Should I use a split lock washer or a flat washer on a 5/16 bolt?
They do different jobs and are often used together. A split lock washer like the JBLW516 is a helical ring that bites into the nut and the mating surface as it is torqued down, resisting loosening from vibration. A flat washer spreads load and protects the surface but does nothing against vibration. On equipment, motors, panels and strut connections that shake, the split lock is the one you want; add a flat washer under it if the material is soft or the hole is oversized.
3) Are these 5/16 split lock washers suitable for electrical panel and conduit work?
Yes. Metallics lists the JBLW516 for the electrical, plumbing, heating and air conditioning trades, which is where 5/16 hardware shows up most: strut and channel connections, hanger rod, panel and enclosure mounting, and equipment anchoring. The silicon bronze construction also suits grounding and bonding hardware where copper-compatible metal is called for.
