HSFG stands for High Strength Friction Grip and as the name suggests they make use of friction.
Advantages:HSFG bolts have the following advantages when compared with normal bolts:
(i) The performance of preloaded HSFG bolts under fatigue loading is better because the prestressed bolts are subjected to reduced stress range during each loading cycle when compared with unloaded bolts.
(ii) To suppprt structures to avoid the loosening of bolts from vibration.
(iii) HSFG bolts are used in connections to avoid slip movement which makes whole structures to break down.
(iv)HSFG Fasteners are used where high tensile strength requirements is more.
