Reliable, safe, and easy-to-use HEICO-LOCK(R) locking device An explanation of the principles supporting this locking device. 1. Hardness difference: H (HEICO) > H (material) The surface hardness of the washer is harder than that of the general fastening material and nut/bolt, and it firmly spikes into the surfaces of the fastening material and bolt/nut. 2. Friction difference: μ (a) > μ (i) Friction coefficient of the wedge-shaped cam surface on the inside of the washer: μ (i) Friction coefficient of the radial tooth surface on the outside of the washer: μ (a) 3. Angle difference: α > β Angle of the cam surface on the inside of HEICO-LOCK(R): α Lead angle of the screw: β 4. Axial force (preload) difference: F (dyn) > F (stat) Dynamic axial force (dyn) occurring in an environment where a load in the loosening direction is present Static axial force (stat) during tightening The locking effect of the HEICO-LOCK(R) series has been demonstrated through vibration tests in accordance with international standards. - German Industrial Standards (DIN 65151, DIN 25201-4) - U.S. Aerospace Standards (NASM 1312-7)
