Which bolt is used to create a pivot point?

Which bolt is used to create a pivot point? Correct Answer Shoulder bolt

Explanation:

Shoulder bolt

  • Shoulder screws are used in punch and die construction.
  • They are also known as shoulder bolts, stripper bolts or set screws.
  • They are defined as screws with an unthreaded shoulder that is larger in diameter than the threads.
  • Shoulder screws are used for rotation or sliding applications, such as pulley shafts, in punch or die works for example in order to limit the die springs in the stamp housing or the mould, or for use as bearing pins.
  • They are also used as axels and pivot points.

​ 

U bolt 

  • A U-bolt is an industrial fastener in the shape of the letter U with two threaded arms (or legs) extending from a curved base.
  • U bolts are typically used to support pipework or to attach a part to a pole, beam or wall, where the “u” shape keeps it firmly in place, adding stability to the support.
  • U-bolts are designed to be inserted through holes that have already been drilled.

J Bolt 

  • J-type anchor bolts have a bend at one end to grab onto the concrete or masonry structure.
  • These types of anchor bolts are normally inserted into the concrete as soon as it is poured.
  • The concrete cures, and securing retains the bolts in place.  
  • This type of anchor bolt is shaped like the letter J, so it can not be pulled out of the concrete after the concrete has hardened.
