  Also known as a ‘fully threaded bolt’, the hex head also allows for higher torque to be applied with a range of conventional tools making them a versatile choice. 

  Versatile and when coupled with the 1/4″ UNF nuts sees these hex head set screws widely used across many industries by DIY enthusiasts and professionals alike.
