Close call today... I ordered and received 10 of these spiral flute taps costing about $15 each. They were supposed to be 5/16-18 and that is what the box says as well as the laser etching on the shank. Look closely at it while held right next to a 5/16-18 bolt. Look a little odd? Yep, it's a 7/16 tap. I checked the label on the box and the writing on the tap a couple times and was almost ready to proceed. It was setup in the mill and ready to go when my instincts kept telling me something was wrong. At the last moment, I measured with a caliper. Thank heavens I didn't plunge it under power.
