There are over ten types of bolts used in everyday applications. For example, hex bolts have a high tensile strength, so they are perfect for bridge construction. Bridges need tension and compression to support themselves.
But, how would you know what type of fastener to use in other situations? Each type of bolt works best in specific conditions.
Does it matter how you're using the bolt? Should you consider the fastener material when deciding what bolt to use?
There is a lot to cover about
If you’re busy on the worksite all day, the last thing you need is problems with installing your fasteners. You may have previously installed a bolt or nut and realised that the thread is damaged or even seized.
This type of damage is often referred to as Galling.
Galling is a common issue when working with fasteners. With some basic knowledge, you can save time and money by using the recommended installation practices.
Firstly, what is thread galling?
Galling typically occurs in the bolt installation process where friction and pressure damages the thread. During the tightening process, the pressure and friction between surfaces causes the fasteners’ protective surfaces to wear down, and in some cases, galling will cause the bolt to seize completely to
