[Case Study] Reduction of Maintenance Frequency and Improvement of Quality through Anti-Loosening Measures

[Case Study] Reduction of Maintenance Frequency and Improvement of Quality through Anti-Loosening Measures

A case where Nord-Lock washers contributed to a reduction in maintenance frequency.

Here is a case where we proposed "Nord-Lock washers" to an industrial machinery manufacturer. They were using hex socket bolts (CAP) in their binding equipment, but there was an issue with loosening occurring after delivery. After our proposal, the reports of loosening troubles, which had been occurring almost every month, dropped to zero. [Overview of the Issue] ■ Hex socket bolts (CAP) are used in the binding equipment, but loosening occurs after delivery. ■ There were 2 to 3 reports per month, and maintenance was performed at the customer site each time. *For more details, please refer to the related links or feel free to contact us.

Hexagon socket bolt (cap)

Hexagon socket bolt (cap)

Improved reliability and workability due to prevention of loosening with high tightening force.

Hexagon socket bolts (caps) are generally used without being paired with nuts, so referring to them as screws is more accurate. However, since the name hexagon socket bolt has become widespread, they are also called cap bolts. The applicable strength grades are 8.8, 10.9, and 12.9. They are tightened with a hexagon rod wrench (with a maximum neck length of 1,000 mm). *In urgent or emergency cases, please direct any technical inquiries through our website.
