Thomas & Betts 141 – Frequently Asked Questions

1) Is a locknut enough to secure a connector to a panel, or do I need a bushing too?
The 141 locknut is the fastener only. It pulls the connector shank tight against the enclosure wall and bites into the sheet metal for the mechanical connection. Where conductors pass over the threaded end, you still need a separate insulating or grounding bushing, and on a grounded run you may need a grounding locknut or bonding bushing instead. Order those items separately.
2) What is the part number to order for the Thomas & Betts 1/2 inch steel locknut?
Order Thomas & Betts model 141. That is the 1/2 inch case hardened steel locknut, and it is the only model on this product, so there is no size or finish option to specify.
3) Will a steel locknut hold up in a panel that sees vibration from machinery?
That is what the design is for. The 141 is case hardened steel, and the locknut profile is made to keep its grip through vibration and thermal cycling rather than backing off like a plain nut. Case hardening gives the tangs a harder surface so they keep their bite into the enclosure wall over the life of the installation.
4) Can I use the Thomas & Betts 141 locknut on both commercial panel work and residential rough-in?
Yes, the same 1/2 inch nut covers both. It is used for panel and enclosure terminations, conduit system assembly, industrial wiring, and residential work, which is why it is a common bulk item for maintenance crews standardizing on one fitting size.
5) Is this a steel locknut or a zinc die cast one?
Steel, and case hardened. That matters if your spec calls out steel fittings, since die cast zinc nuts are softer and can strip or crack when torqued hard against a thick enclosure wall.
