B-LINE 10243 D – Frequently Asked Questions
1) What thread size is the Eaton B-Line 10243 D flange nut?
It's a 3/8-16 flange nut, written .375-16 in the spec data. That's a 3/8 inch UNC thread, so it mates with standard 3/8-16 threaded rod, bolts, or studs. The flange gives it a wider bearing face against the panel, .68 inch across, with a .375 inch nut height.
2) What is the 10243 D flange nut actually used for on an Eaton B-Line enclosure?
It's the fastener for large 3R panel mounting on wall-mounted enclosures. In practice you use it to secure the mounting panel hardware inside the box rather than to hang the enclosure itself. Mounting method on record is wall.
3) Can I use this flange nut in a NEMA 12 or NEMA 4 enclosure?
Yes. The 10243 D accessory is rated for NEMA 12 and NEMA 4 enclosures, so it's suitable for dust-tight, drip-tight industrial boxes as well as hosedown/watertight NEMA 4 applications.
4) Is the Eaton B-Line 10243 D UL Listed?
UL Listed, per the manufacturer spec data. That matters on institutional and MRO jobs where every component inside a listed enclosure assembly has to carry a listing of its own.
5) How do I order the right part number for the B-Line 3/8-16 flange nut?
Order it as Eaton B-Line model 10243 D. That is the manufacturer part number, and it's the only model configuration for this flange nut, so there's no finish or size option to specify.
6) Will a standard 3/8-16 hex nut work instead of this flange nut?
Thread-wise yes, but the flange is the point. At .68 inch across the flange spreads load over the panel and seats flat without a separate washer, which is why B-Line calls it out for large 3R panel mounting. A plain hex nut of the same thread needs a washer added to do the same job.
7) How much does the B-Line 10243 D weigh?
The listed product weight is .21 lb. Worth knowing because that figure, against a single small nut, indicates the part ships as a multi-piece mounting pack rather than one loose nut.
