Key Features
Overview
The Klein Tools Combination Square, 12-Inch (93512CS) is a full-size combination square with a 12" stainless steel blade and an orange cast-zinc body. This is a combination square designed for layout, marking and alignment work where a 6" blade runs out of reach: wide boards, framing, panel layouts and longer depth settings.
The blade reads 0 to 12" with 1/8", 1/16" and 1/32" graduations. Those graduations are etched into the stainless steel, so they are high-visibility, permanent and resistant to wear in tough environments.
The body is cast zinc (Zamak-3) with an orange powder-coat finish, giving a solid, comfortable feel and reducing hand fatigue over a long day of layout. Its precision-machined 45-degree and 90-degree edges deliver the accuracy layout depends on, and the body detaches so the blade can work on its own as a rule.
The oversized ergonomic thumb screw allows quick, secure locking adjustments with better control. An integrated screw-in scriber and bubble vial add marking and quick leveling, with components that stay secured in the body. Not magnetic.
Size and weight: about 12" x 3/4" x 5-3/16" (30.5 x 1.9 x 13.2 cm), 11.2 oz (318 g).
Who should buy it: carpenters, electricians laying out panels and racks, HVAC and metal trades, and serious DIYers who need a full-length square that stays accurate.

Pro Tip
Check a combination square against itself: draw a line along the 90 edge, flip the square over and draw again from the same point. If the two lines match, the square is true.
