Nord-Lock Washer (R) X Series

Nord-Lock Washer (R) X Series

Simultaneously solves rotational and non-rotational looseness! Since it does not rely on friction, it can be used in conjunction with lubricants.

The "Nord-Lock Washer® X Series" is a product that can simultaneously solve two important issues in bolt fastening: "rotation loosening due to vibration" and "non-rotation loosening due to settling or relaxation of materials such as metal." Rotation loosening is prevented by a wedge locking mechanism, while the "spring effect," a feature of the X Series, addresses non-rotation loosening. When the bolt is tightened, the washer, shaped like a disc spring, flattens and grips the joined components. 【Features】 ■ Prevents both rotation loosening and non-rotation loosening simultaneously ■ Can be used with lubricants as it does not rely on friction ■ Provides a loosening prevention effect that is safe, easy, and reliable for anyone *For more details, please refer to the related links or feel free to contact us.

Why doesn't HEICO-LOCK® loosen?

Why doesn't HEICO-LOCK® loosen?

Why doesn't HEICO-LOCK® loosen?

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 surface 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) in an environment where a load in the loosening direction occurs 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)

For secure, reliable, and easy fastening, use Hi-Lock Wedge Lock Washers.

For secure, reliable, and easy fastening, use Hi-Lock Wedge Lock Washers.

Reliable, safe, and easy HEICO-LOCK® standard type.

HEICO-LOCK(R) wedge lock washers protect bolts from rotational loosening not through friction, but by using 'axial force (preload).' Born in Germany, HEICO-LOCK(R) provides 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 surface has radial teeth. ■ The radial teeth on the outer surface of the washer firmly spike 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 surfaces 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.
