I'm restoring an old Dixon (304) zero turn with a B&S model 254707-0120-01 engine. I am short one of the mag hold down screws, part #691061. I've tried trying to use dies, SAE and metric, to identify the thread type. I am assuming these are hardware type screws.

Anyone out there that can ID these for me is appreciated.

They are M4-0.80 and will be extremely hard to find other than from Briggs. This is a size between SAE 8-32 and 10-32. 0.80 metric thread pitch is the same as 32 tpi

A lot of mower shops have a junk pile.

It also pays to save every spare screw when scraping out an engine. These here are used on the 08P and 09P engines too.

That's why I use a bin system and a computer with Auto Manager software. I also do regular backups of the databases. The drawback now is when an item gets superseded to NLA as it becomes AWOL. At least supersedes no longer loses the bin locations when superseding to a new part number, if I remember to check merge all data.

Just ran across an oil seal that Oregon stopped making so it got superseded to NLA. When that happens I create a new SKU with the NOS suffix and add the bin location back.

Still it is hard to keep all the bins update as I only got 2,061 different items I am keeping track of with nearly 16,000 pieces in all.

I think M4 x 0.8 is a fire arm thread
There is also an M4 x 0.75 which is an old Japanese Metric thread prior to the ISO days when metric threads were standardized/
