Triangle Head Bolts with Flange

Triangle Head Bolts


Flanged triangle head bolts from ITA Fasteners are complicated security screws which require special tools to fasten and unfasten. Hence, they find their application in highly secure applications like the construction of ATMs and lockers. They comprise in a single component, a flange headed bolt and triangular heads. Please note that these bolts are not as secure as other security screws and therefore, need to be used with caution especially if the application's security entirely depends on it. Otherwise, these bolts are excellent at providing minimal security at excellent value for money.

They come with a tall triangular head which protrudes out of through the gap. Like we mentioned earlier, these bolts can only be operated using a special wrench. But since these particular security screws are becoming increasingly common, they have to be used with caution and the awareness that anyone with the intent to break into the locker, can purchase the corresponding wrench. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
