Heat preservation and crack repair technology with almost no risk of secondary crack occurrence, which does not require machining. Here is a list of products for screws and reinforcement materials used in the LNS method.
■□■A completely new metal crack repair that is not welding■□■ Contributes to the extension of equipment lifespan The work process involves drilling → tapping → inserting special screws and reinforcement materials (LOCK), and unlike traditional welding repairs, it does not apply heat that damages the base material of the equipment. As a result, repairs can be completed in a short period, leading to extended equipment lifespan with improved precision, durability, and low cost. The "C Series Pin" is ideal for crosswise cracks that occur on the upper part of the cylinder head or cracks that have developed from plug holes or bearing holes. The "L Series Pin" features a screw hole size and a tapered base. The "LOCK" is used to increase strength across the crack. For more details, please contact us.

Unprecedented amazing screw technology!! Differentiation from other companies with double locking to prevent loosening!
The Lami Lock Screw is a special screw for glasses that eliminates play through a specially designed anti-loosening resin. Regular screws tend to wobble and can become loose, and while using a regular screw with anti-loosening resin can temporarily prevent vibration, it still has the issue of the screw loosening over time. The Lami Lock Screw from Matsumoto Sangyo allows for a complete fastening with two and a half threads thanks to its anti-loosening effect based on Noji Logic (utility model patent pending).
