Square head bolts(it is also known as “น็อตหัวเหลี่ยม“ in the Thai language) are a type of bolt that have a square shaped external wrenching head, thus giving the name square head bolt.

Moreover, U bolts not as commonly used as other bolts get their name from their shape, they are a bolt shaped in the form of the letter “U” with screw threads on either end. Because of their application U bolts are typically described by what type of pipe it will be used to support.
