Need help with screw size

[Jolive]

I have this mower, but have lost the shroud screws. Any help on finding the correct size replacement?

Lets start with both the model number of the engine and the model number of the mower. That have used both phillips headed and hex headed screws to secure those in the past.

If remember correctly they are Briggs PN 691138 which a plastic mounting screw with a double thread design. But there is one other screw design for mounting into metal.

I've had maybe a handful of engines come on with the appropriate screws on the recoil cover. Usually a Phillips wood screw in its place.

Briggs model # =
Crafrsman mower part number =
Serial number if known please =

should be on a tag on the side of the engine shroud if I recall

Looks like it should be part number 690700



Looks like the Craftsman parts diagram is calling for the 690700 and the briggs diagram is saying it is 691138 but both were used on that model of briggs engine depending which decorative cover was used.

The 690700 is for the following cover.

The Sears website shows using the 969 screw with the 921X shroud. If you go to the Briggs eparts and click on the 969A next to the 921X you will get an error message about part not used or not embedded something on that order. The 969A box works on the other shrouds but not 921X on the eparts diagram. So one or both have an mistake.
