Yeah, the email you sent me wouldn't allow input

Had to do the review loading the email in my Chrome browser

I appreciate buying small Machine Screws via FMW Fasteners

I would suggest you put back the chart of specifications like the height of nuts and washers and fender washers cuz we need that spec to make sure the Machine Screw would be long enough for the fastening across our material (in my case, usually a wooden board).

Thanks. Your delivery is quick, and always well tagged.
