Introduction of Large Hex Bolt Marking Tool

In the mechanical and electrical industries, the use of fasteners is ubiquitous. When the fasteners with torsion requirements are completed, the relevant large hexagon bolts must be painted with anti-loosening labels, indicating that the fasteners have been tightened according to the requirements, so as to distinguish them from untightened fasteners, so as to avoid Leakage of fasteners during installation. Labeling can be done during assembly. Play the role of inspection; in the subsequent use of the product, the anti-loosening mark can also be used as a basis for judging the looseness of the bolt and eliminating hidden dangers. Especially in the field of rail transportation, the current status of fasteners directly affects the driving safety and life safety of passengers.
The Large Hex Bolt Marker has a marking tool that quickly forms straight lines on the top and sides of the hex bolt head, the top and sides of the washer, and the marked portion of the product surface. one more time. It effectively solves the problems of inconvenient quick marking, bolt position limitation and unsightly lines in the prior art.

The structural tool of the large hexagon bolt anti-loosening marking tool includes the following parts: 1. Pen holder; Pen cap; 3. Inner protrusion of pen cap; 4. Ink tube cavity; 5. Automatic reset ink core device; 6. Ink core sleeve; 7. Ink core cover; Ink core; Spring; 11. Groove; 12. Movable sponge block; 13. Boss cavity; 14. Fixed sponge block; 15. Pen cap.

When marking, just put the bolt anti-loosening line on the outer ring of the washer, fix the position of the bolt anti-loosening line marking pen on the surface of the mechanical and electrical product, and then press the bolt anti-loosening line. Marking pen, so that the cavity at the bottom of the pen holder wraps the bolt head, and the bottom of the pen holder touches the surface of the mechanical and electrical product, remove the marking pen, complete the marking process, and then the bolt can be placed on the surface of the mechanical and electrical product. Scribing parts consisting of the top and sides of the bolt head, the top and sides of the washer, and the surface of mechanical and electrical products are quickly formed into straight lines at one time.
