Reverse screw is the key point! Allows fine adjustment of the door frame! Suitable screws for efficient construction and renovation.
The "adjustment screw" allows for fine-tuning of the door frame. By turning it to the right, the frame moves closer to the post, and you can screw in the adjustment screw at the stop. By turning it to the left, the frame moves away from the post. When turned in reverse (to the left), the frame lifts. It is suitable for renovation with reduced construction work. This screw has a deep cross hole, making it resistant to head stripping and slipping. 【Features】 ■ Suitable for reduced construction and renovation ■ Reverse thread is a key point ■ Deep cross hole, resistant to head stripping and slipping *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Dandori Vis Co., Ltd. manufactures and sells original construction hardware, screws, and resin products used in new housing and renovations. The name "Dandori Vis" comes from a term used in the construction industry, "Dandori Hachibu, Shigoto Nibun," which emphasizes the importance of planning and efficiency. Since its founding, we have focused on selling convenient and innovative products to construction professionals and have prioritized the development of products that enhance efficiency on construction sites ahead of our competitors. In recent years, there has been a demand for shorter construction processes and reduced labor, and as the workforce of craftsmen is rapidly aging, there is a tendency for the lifespan of products demanded by the market to shorten. We believe it is our mission to quickly respond to changing construction methods and deliver the products developed by Dandori Vis (fresh information) to craftsmen, thereby contributing to the creation of comfortable living spaces. Thanks to the tireless efforts of our founders, including participation in national exhibitions, Dandori Vis has surprisingly high recognition among construction professionals.
