Bridgeport Fittings 163-G Mighty-Bond Zinc Grounding Locknut with Aluminum Lug

The Bridgeport Fittings 163-G Mighty-Bond zinc grounding locknut with aluminum lug is designed to create a secure, low-resistance bonding connection between rigid, IMC, or EMT conduit and a metal enclosure, panel, or box. This locknut series is available in trade sizes ranging from 1" to 4", so installers can size the fitting to match the conduit and enclosure or panel knockout on the job. Every size in the 163-G Mighty-Bond family features a solid zinc body paired with an integrated aluminum grounding lug that accepts a bonding jumper, giving installers a single fitting that both secures the conduit and establishes an equipment grounding path. The Mighty-Bond design eliminates the need for a separate grounding bushing or clamp on many installations, saving labor time in panel and enclosure terminations. This locknut is built for electricians and contractors who need a dependable grounding connection on commercial, industrial, and institutional projects, whether the run is a compact 1" conduit drop or a larger 4" service entrance.

Key Features

  • Trade Size Range: Available from 1" up to 4" to fit standard conduit and matching enclosure or panel knockouts across a wide range of installations.
  • Durable Zinc Construction: A solid zinc body provides strength and corrosion resistance for long-term reliability in the field across every size in the series.
  • Integrated Aluminum Grounding Lug: A built-in aluminum lug accepts a bonding jumper directly at the locknut, keeping the grounding connection compact and secure regardless of conduit size.
  • Mighty-Bond Design: Combining the locknut and grounding lug into one component simplifies the bill of materials and speeds up installation compared to separate grounding hardware.
  • Grounding Locknut Function: Bonds conduit to enclosures, panels, and boxes to help maintain a continuous, code-focused equipment grounding path.
  • Threaded Locknut Body: Threads onto conduit to secure the raceway to the enclosure while the aluminum lug provides the bonding point, sized appropriately for each trade size offered.

Bridgeport Fittings 162-G – Frequently Asked Questions

1) What conduit types does the Bridgeport 163-G Mighty-Bond grounding locknut work with?
The 163-G Mighty-Bond locknut threads onto rigid, IMC, or EMT conduit and secures it to a metal enclosure, panel, or box while bonding it at the same time. Trade sizes run 1 inch through 4 inches, so match the fitting to the conduit and the knockout it lands in.
2) Do I still need a separate grounding bushing if I use a Mighty-Bond locknut?
No, that's the point of the fitting. The aluminum lug is built into the zinc locknut body and accepts the bonding jumper directly, so on many terminations you skip the separate grounding bushing or clamp and drop one line item off the material list.
3) Which part number do I order for a 1 inch versus a 4 inch conduit?
Two part numbers cover the ends of the range: 163-G is the 1 inch fitting and 162-G is the 4 inch. Order by the trade size of the conduit, not the knockout diameter.
4) What is the Bridgeport 163-G locknut made of, and will it hold up in a damp industrial panel?
Solid zinc body with an aluminum grounding lug. Zinc gives the strength and corrosion resistance for long-term service in commercial and industrial panels; the aluminum lug is where the equipment grounding conductor lands.
5) Can I use a grounding locknut instead of a standard locknut to keep my ground path continuous?
Yes, and that is the usual reason to spec one. A plain locknut only mechanically holds the raceway to the box; the 163-G Mighty-Bond does that job and gives you a lug for the bonding jumper, so the equipment grounding path carries through the enclosure wall at the same termination.
6) Is the Mighty-Bond locknut suitable for a 4 inch service entrance termination?
Yes. The series tops out at 4 inch trade size, and that size is intended for larger terminations including service entrance conduit into a panel or enclosure. The 4 inch fitting is part number 162-G.
7) Is a grounding locknut the right choice for a retrofit where the existing conduit is already installed?
It works for retrofit as well as new construction. Because it threads onto the conduit like an ordinary locknut, you can pull the old locknut and install the Mighty-Bond in its place to add a bonding point at an existing panel or enclosure entry, as long as the trade size falls in the 1 to 4 inch range.
8) Can I standardize on one grounding locknut series across a whole building's panels?
The 163-G Mighty-Bond family runs 1 inch to 4 inch with the same zinc body and integrated aluminum lug design in every size, so a facility or MRO buyer can spec one series for panelboard and enclosure grounding across conduit drops of very different sizes and keep the stockroom to one line.
