Source for Post and Screw tool hardware

[Chad Lowe]

As part of my Quixotic quest to have an accurate square, I am (re)building a 24" T-square for mid-range layout tasks, and I am having trouble sourcing some parts. I need some very small Post and Screw, aka Chicago Screw, aka Sex Bolt for the three fastening locations between my 24" rule and the "T" of my T-square. I have other tools and jigs that came with this size of small nut and bolt, but a solid hour with google has not helped my find a source of my own. Does anyone have a suggestion as to where I can find these in very small sizes?

McMaster Carr has a large selection of the Chicago bolts.

I was always told if they don't have it, you don't need it. Good luck

Better still - their east coast mega-monster-godzilla distribution center is 20 minutes from my house. I have even been able to order on a Sat am by phone, and con them into a customer pickup later that morning.............
