having trouble finding replacement tap screws (Craftsman 536.881800)
Hello,
I noticed today that one of the screws connecting the augur housing to the drive is missing. I thought I would just replace all of them but I am having trouble finding them online.
The part is listed as 122 and 123 on this part diagram from partstree.com,
https://www.partstree.com/parts/murr...4-sears/frame/
The key says that part 122 is tap screw Murray 25X021 and part 123 is tap screw Murray 25X020. A check for these part numbers does not return any hits at amazon or any of the other places where I have bought parts before.
I found a few links, but they all said something about being discontinued.
The information from partstree says,
Murray 25X021 = SCREW.31-18X0.75 WAHH
Murray 25X020 = SCREW.31-18X0.50 WAHH
Is there some generic hardware that I can get to replace these? The holes are tapped, so the threading needs to match. Is there some place to get these that I am not finding?
Thanks for the advice,
LMHmedchem

Have you checked out home depot, lowes, Menards, etc?

I think they are regular 5/16"-18 x .75 hex head screw bolts?
Here's a picture of an MTD one:

Have you tried OMB Warehouse? All 3 screws on one side fell out on my noma blower during the bombogenesis. I ordered three of them on OMB and waiting for them to get delivered.

They don't need to be tap screws. Just remove one from the other side and head on down to the hardware store. A simple bolt and washer will fix you up. Buy a small tube of medium strength Lock-Tite and put it back together.
There's just one thing I'll guarantee , the best things in life, they sure AIN'T FREE !!

I just go to my screw assortment drawer ... before I discard anything, I remove all the nuts and bolts ... usually find whatever I am looking for ...
As mentioned, just pull out another one, and go to the local hardware or big box .. grab an extra while your there, throw it in your screw/bolt drawer, or start one ..

I am with oneacer. I have a old Craftsman tool box full of every fastener I saved over the last 30 years. Usually find what I need. In the event my trusty stash fails me, I head to Fastenal. If they don't have it, they don't make it.
I don't mind spending money, I mind wasting money.

They have never come loose before that I can remember. Do you think they are coming loose now because of wear and age or is it more likely that I just didn't get them tight enough in the first place?

home depot has them as many stores do. bring one w/you and ignore the "self tapping" but buy washers and lock washers. thread pitch and bolt width is what ur trying to match.
i myself like using at min grade 5 bolt if it has todo w/the frame such as the bucket attaching to the drive box, but my machine is an old school heavy sb and it has, iirc, grade 5 or 8
