11H-4-4R Combination Square

11H-4-4R lg
The only Precision Combination Square available that delivers flawless precision. Made in Athol, Massachusetts, the founding father of Starrett designed and patented the Combination Square. Since its inception in 1880, no other combination square can match Starrett quality, precision, reliability and performance. If your tasks do not require precision, any square will do. But if you need accuracy and precision, only Starrett will do.

The Starrett 4" Combination Square with Square Head features a reversible lock bolt, and hardened steel, photo-engraved blade with regular finish. This product also includes a cast iron head with black wrinkle finish. 4", 4R Grad, Regular Blade.

From Customers:

"I sprung for a good combination square because I finally got tired of my cheap little Harbor Freight square. Wow. I would have bought this years ago had I known how good this tool is. Precision precision precision. Every detail of this tool is perfect. Perfect measurements, perfect 45 degree angle, perfectly square, easy to tighten, easy to flip the ruler around, the scribe fits perfectly into place, the leveling bubble is exact...There is absolutely no flaw to this tool. Ever work on something only to figure out something wasn't square and had to spend more time fixing the mistake? Yes.. that's why I bought this. Save yourself the time and and effort and invest in precise tools. I made this purchase after making an error on a box that I was building due to a lackluster combination square and breaking my rule of triple checking measurements before committing to a cut. This is not something I would have purchased a couple years ago and it’s not a tool everyone should invest in. If your work doesn’t require precision (cutting 2x4’s, general building, etc.) than you can spend $15 on a combination square and be fine. If on the other hand you’re into woodworking projects this is an investment you should make. It would also make an excellent gift for someone who fits that description as well."
