For secure, reliable, and easy fastening, use the Hicolock Wedge Lock Washer.
HEICO-LOCK® Wedge Locking System
Reliable, safe, and easy HEICO-LOCK® standard type.
HEICO-LOCK(R) wedge lock washers protect bolts from rotational loosening through 'axial force (preload)' rather than friction. Born in Germany, HEICO-LOCK(R) offers high anti-loosening performance and reliability even under intense vibrations and dynamic loads. The anti-loosening effect of the HEICO-LOCK(R) series has been verified through vibration tests in accordance with international standards. - German Industrial Standards (DIN 65151, DIN 25201-4) - U.S. Aerospace Standards (NASM 1312-7) 【Features】 ■ The inner surface of the washer has a wedge-shaped cam surface, while the outer side has a radial tooth surface. ■ The radial tooth surface on the outer side of the washer firmly spikes into the bolt/nut and the joined material. ■ The movement of the system occurs only between the wedge-shaped cam surfaces on the inside of the washer. ■ Movement at the wedge-shaped cam surface effectively increases the axial force of the bolt. ■ It provides reliable fastening strength under dynamic loads. *Please feel free to contact us for more details.
