Advantages of controlled bolting techniques

Correctly tightened bolts make use of their elastic properties and should behave like springs to work effectively. Their spring analogy is attributed to when load is applied as the bolt stretches and tries to return to its original length, creating compressive force across the joint members.

The elongation applied within the elastic range is relieved when the load is removed and the amount of elongation increases when more load is applied. It is the further application of load which takes the bolt to a point where it begins to fail, this is termed its ultimate tensile strength (UTS).  At the UTS-point, if additional force is applied to the bolt, it will continue to elongate until it finally breaks. To prevent bolt failure, attention should be paid to:

• The grade of bolt
• The equipment being used
• The operator skill in applying the correct controlled bolting techniques
