BIG 12-Point Nut with captured washer

[Rick Iverson]

Gents;

West Coast Fabrication used to provide these mid-year VD front stub axle nuts with retained washers. Apparently no longer. Any sources would be greatly appreciated.

Could it be an NAS1726C ?

ARP makes these or at least used to. I have used them for years on all sorts of formula cars. Bought a bunch when I was restoring my 78B and am now out. If you find them please post

I looked in an old, treasured Coast Fabrication print catalog (2009) and found what appears to be this nut --

7/8 - 14 UNF 12-point Nut-washer assembly = Part No. KFN542-14 (the "14" in P/N is for 14/16" = 7/8' bolt diameter, coincidentally the same as the thread pitch).

Doing an internet search for the P/N, I find several possible suppliers. All seem to require a request for a quote.

Here is one URL --

Others -- https://jet-tek.com/k-fast/kfn542/

A different P/N that looks the same -- https://catalog.howmetfasteners.com/...-ksi/vn465a144

PS -- The following URL will get you to a company that apparently absorbed Coast Fabrication (don't know when & this specific nut is not in their website) --

This may very be the ticket. You are magnificent, friend. MOST grateful.

Did you try Clarendon Fasterner who bought Coast? https://www.clarendonsf.com/

I looked @ their online catalog & they didn't have one as large as what Rick wants (7/8-14 UNF). I think they maxed out at 1/2 or 5/8 bolt diameter. It might be worth contacting them to see if they can get them, just not in their catalog.

PS- Rick, thanks for the compliment! And don't forget to post up any of your findings about a source for these.

If you don't have to have the captive washer there are some NAS1805-14L on Ebay.

From Clarendon;

• 12 point Jet nut
• 1"
• 12 TPI
• RHT
• Captured washer
• PN: KFN 542-1612

These were unique to the RF-96. Does ANYONE have a spare I can buy, beg, borrow or steal?

[Rick Iverson]

Please, there is no money that we cannot resolve this issue.
