Marker for alignment marks 'Disappearing Line' that won't let you miss bolt looseness.

Active in inspections at construction sites, such as road signs and railway tracks! Visualize bolt looseness with an indelible "mark."

To check for bolt loosening, the line drawn from the bolt to the nut and the seating surface is called the "alignment mark." Alignment marks are used in various situations, including the installation bolts for road signs, railway rail fastening bolts, and in construction sites, highways, and aircraft. 【Are you aware of the standardization of "alignment marks"?】 The Ministry of Land, Infrastructure, Transport and Tourism has standardized the implementation of "alignment marks" after tightening bolts used for road signs and other applications. The inspection frequency is generally once every five years, so it is important that the alignment mark is clearly visible five years after it has been applied. However, the markers that have been used for alignment marks until now have sometimes lacked a durability of five years and have faded away. Our company, Okitsumo, has developed 'Disappearing Line,' which has excellent weather resistance, ensuring that the line remains visible even after five years outdoors, with minimal fading, making it possible to visualize bolt loosening!
