[Case Study] Prevention of Foreign Matter Contamination in Food Manufacturing Lines and Reduction of Inspection Work

A case where Nord-Lock washers were proposed to prevent the loosening and falling out of screws.

Here is a case where we proposed the "Nord-Lock Washer" to a food processing manufacturer. In the final stage of packing the manufactured liquid, screws used in the equipment line fell off and were shipped without anyone noticing, resulting in contamination of the product. After our proposal, there have been no signs of screw detachment, and the emergency measure of inspection work has been eliminated, leading to a reduction in the burden on the workers. [Overview of the Issue] ■ Screws used in the equipment line fell off and were shipped while contaminating the product without anyone noticing. ■ The issue was discovered by chance during an inspection at a retail store, leading to a halt in production and a recall of all products. ■ Since then, all areas with potential for detachment have been addressed with emergency measures. ■ The inspection work before starting operations has become an excessive burden, so we want to implement a fundamental solution. *For more details, please refer to the related links or feel free to contact us.

Bolt and nut locking, Nord-Lock

The locking method of Nord-Lock has passed the German standard DIN25201.

Nord-Lock uses wedge-shaped cams and employs tension instead of friction, making it a unique loosening prevention method. It is a loosening prevention system that is incomparably safer than conventional methods.

HEICO-LOCK® Wedge Locking System

A locking system that maintains bolt fixation through axial force (preload) rather than friction.

The "HEICO-LOCK(R) Wedge Locking System" protects 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 side has a radial tooth surface. ■ The radial tooth surface on the outer side of the washer firmly spikes into the underside of the bolt/nut and the joined base material when the bolt is tightened. ■ The movement of the system occurs only between the wedge-shaped cam surfaces on the inside of the washer. ■ The movement at the wedge-shaped cam surfaces effectively increases the axial force of the bolt. ■ It provides a reliable fastening force under dynamic loads. *For more details, please download the PDF or contact us.

Why doesn't HEICO-LOCK(R) 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 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)

Lock Washer "RIPP LOCK"

Vibration-resistant! A new fastening solution that allows for easy assembly and disassembly, and is reusable.

"RIPP LOCK" is a lock washer with radial ribs on both sides. The pitch angle of the ribs is designed to be larger than the screw pitch. When screws and nuts are assembled, the ribs bite into the bolt seating surface and the clamped part, locking them in place. This provides a high vibration resistance effect. 【Features】 - Easy assembly and disassembly - reusable - Contributes to the reduction of the number of parts - Suitable for all materials up to grade 12.9 - Ideal for applications with slot holes For more details, please contact us or download the catalog.
