M1101/M1102 Bolts for Canvas Cover

[DavidM310]

Hello!

I have an M1102 trailer and recently picked up a canvas cover with about 90% of the parts. I’ve sourced most of the missing hardware from vendors, but I still need help with the last few items: the 32 bolts for the bow brackets and the 8 bolts for the roof supports. I’ve attached a picture with the bolt locations in red.

From Eastern Surplus
Screws for brackets: PN: B18210B403BC088N
Screws for roof support: NSN: 5305-01-109-0587 PN: MS24630-66

Does anyone know the correct bolt size, pitch, and thread before I start scavenging at the local hardware store or know of a vendor with bolts in stock? I will contact Eastern Surplus to see if they can sell the screws separately from this kit: https://www.easternsurplus.net/Part...r-and-Bow-Kit-with-Hardware-shown-M1101-M1102.

Thanks in advance!

If memory serves the TM calls out 3/8" - 16 x 2" for the bow mounts. When I started putting my bow mounts on anything longer than 1 - 0.75" interferes with the other bolts. I have not got to cutting my bolts down yet so I do not have an exact length. I do not know anything about the roof support bolts.

Thanks for your input as it helped decode the part numbers.

I reviewed the TM and there's two PNs listed: B1821BH038C075N and B1821BH038C088N. The first bolt should be a 3/8-16 x 0.75 and the second bolt should be 3/8-16 x 0.88 based on the part numbers. The difference I believe is that the longer bolt is used with a flat and lock washer whereas the shorter bolt is used with just a flat washer.



Under Additional Authorization List



The rain cap supports are PN MS24630-66 which is a 10-32 UNC x 5/8" but under Additional Authorization List, a PN 90190A242 is listed which is a self-tapping #10 x 1/2".



Hope this helps someone in the future.
