Heavy duty lockbolts from Avdel
20 April 2012
For demanding assembly applications where welding is not practical or where conventional bolts struggle to provide a guaranteed and retained clamp load quickly and consistently, Avdel has developed the new range of Infalok lockbolts. These large diameter, heavy duty, two piece structural steel fasteners are capable of delivering a joint clamp (pre-load) of over 250kN and a tensile strength of over 300kN.
Infalok lockbolts come in a wide choice of bolt diameters from 12.7mm to 28.6mm and grip ranges from 6.35mm up to 152.4mm. They are available in two different head forms and various finishes. They are tamper resistant and eliminate the risk of vibration loosening during fastened joint service. Joint clamp performance offered by Infalok lockbolts compares with (or exceeds) equivalent sized Metric Property Class 8.8 threaded fasteners.
