Square-head bolt |
The staffer who turned up this post has seen a few bolts in his time; so he was nonplussed, to say the least, to note that nowhere does Kilchermann mention that there are also hex-headed bolts – with one notable exception, in which Lori "explains" that
"Square-head bolts, which often actually have a hexagonal head, can be used to secure wooden planks and other materials."Ummm, no, Lori, the use of the word "square" specifically refers to four sides. Dumbass! With an opening like that, our staffer soon realized that Kilchermann had no earthly idea what the difference between a square-head and a hex-head bolt is, and conflated them throughout her post; to wit:
- "Square head bolts are typically lag bolts. These lag bolts resemble very large screws and are used when assembling heavy lumber." – No, lag bolts don't "resemble very large screws", lag screws do. Lag bolts are used to assemble all sorts of things, and can have either square or hex heads.
- "The advantage in using square head bolts is that they can be tightened with an adjustable wrench." – Ummm, so can a hex-head... idiot. That's not to mention socket wrenches, which are specifically designed for use with hex-head bolts and nuts.
- "[Electrical] Connections, such as wall outlets and light switches, enjoy the advantages that square head bolts provide when being used in close quarters." – "Enjoy"? Moron.
