HEICO-LOCK® WEDGE LOCKING SYSTEMS
HEICO-LOCK® provides reliable protection against the self-loosening of bolted connections. The product portfolio includes not only the proven HEICO-LOCK® wedge lock washers but also innovative variants and user-friendly combination products, such as the HEICO-LOCK® combi-washers, which received the Best of Industry Award in 2023.


HEICO-TEC® TENSIONING SYSTEMS
By using HEICO-TEC® tensioning elements, even large bolted connections can be pre-tensioned easily, quickly, and reliably with the help of a torque wrench. The intelligent orce distribution makes this possible. Instead of pre-tensioning a large bolted joint with high tightening torque and large tools, HEICO-TEC® tensioning elements allow multiple smaller pressure bolts to be tightened with significantly less torque to achieve the required preload force.
