B-LINE 10243 A – Frequently Asked Questions
1) What thread does the Eaton B-Line 10243 A flange nut take?
It's a .375-16 flange nut, so it threads onto 3/8 inch bolts or studs with 16 threads per inch (3/8-16 UNC). If the panel mounting studs in your enclosure are 3/8-16, this nut mates with them; anything coarser or finer, or a metric stud, will not run on.
2) What is this B-Line flange nut actually used for in an enclosure?
It's the fastener for large 3R panel mounting in wall mount enclosures. The nut secures the panel mounting hardware inside the box, rather than being part of the enclosure body or the door latching.
3) Can I use the 10243 A flange nut in a NEMA 12 or NEMA 4 enclosure?
Yes. The accessory is rated for NEMA 12 and 4 enclosures and is UL Listed, so it can go into a dust-tight or watertight wall mount box without compromising the rating, since it is interior panel mounting hardware and does not penetrate the enclosure wall.
4) How much bearing surface does the B-Line 10243 A flange nut cover?
The flange measures .68 in across, with an overall height of .375 in. That .68 inch diameter is what spreads the load, so it seats over a clearance hole up to roughly half an inch without needing a separate washer. Each nut weighs .09 lb.
5) What part number do I order for the Eaton B-Line .375-16 flange nut?
Order by manufacturer part number 10243 A from Eaton's B-Line series. There is one configuration, so there is no finish or size option to specify.
6) Does buying the 10243 A flange nut give me the whole panel mounting kit?
No. It is the .375-16 flange nut only. If you're building out a large 3R panel mount in a wall mount enclosure, you'll still need the panel, the mounting studs or channel, and any brackets the assembly calls for.
