Cage nuts

[Jordan Baker]

Anyone know if a source for original style cage nuts? These are found on the nose of the Cab13 Chevy trucks.

Hi Jordan. I bought some from a company in Calgary called Bolt Supply House. Ill check the details when I get home to see if I have a reference number or brand. What size are those?

Macs auto has them in any size I ever needed.

Facca here in London has sold me 1/4 and 5/16 but they are NC and the original CMP ones were NF. I settled for NC.

Thanks, ive looked at the sources listed and nothing like these ones.

These ones go into a square hole on the nose, then there is 4 little tabs that fold over. On the backside the square nut is held by 4 tabs. As for the thread. The originals that ive got were 1/4" NC

This is what the modern ones look like compared to the picture with the ruler of what the originals looks like.

These are the ones o bought for the floorboards in my M38A1 (1/4” NC).
There are a couple of numbers on the sides. See photo. After thinking about it further, I may have purchased them from a company called Foothills Fasteners in Calgary. I seem to remember them being ordered in for me.

Hi Harry


Over the years I've seen a wide variety of cage nuts used on CMPSs and I've have the suspension that they used what they could get. So what I did was tried to match what was there. Failing that I replaced all the caged nuts in a particular area to match.


When you are looking remember to look for the bulk suppliers you may find as I did suppliers will sell you 100 for the what other sources will charge you for the 8 you need. I had lots left over, but is sure nice to open the box and pull out 5 of the 1/4x20 caged nuts when your fabricating something that needs a blind fastener.


Cheers Phil
