A: Different thickness trims would kick up the squar if they did not have the thin side
A: It's for quick reference markings of 1/4" or 3/8" which is useful for trim squares like this one.. This is from the manufacturers website. "A 1/4" & 3/8" dual measurement heel also allows you to perform quick marks." Hope this helps.
A: It is two difference distances on each side. Useful for marking the center of 1/2 and 3/4 boards. That's my take.
A: Yes, it is small and very accurate.
A: Yes, it works very well as a small square
A: As precise as a speed square can be. No moving parts, lol.
A: I would guess +/- 1-2 degrees. Not engineer's quality, nor does it need to be for average wood-based construction.
A: I checked this on a calibrated optical comparator with a digital readout and it is within .0001 over the 4 1/2 inch length. In my book, that is pretty precision!
A: not enough for machine work, if that's what you're asking.
A: Know this is a little late but might help someone reviewing the FAQs. Just received mine today, it is definitely not a precision square. The 90 degree angle is actually 90.8 degrees, one 45 degree is 45.4, the other 45 is obviously 43.8 degrees. Very disappointed, returned the square immediately.
A: Laser etched markings provide superior accuracy.
A: They are available in some locations. I just checked stock at my local store and they have 9 in stock.
A: Bought last week. Does the job.
