Introducing tapes that can adhere to oil surfaces and functional adhesive tapes!: This time, we introduce the ‘Tape that can be applied to oily surfaces‘ for workplaces dealing with oil. This new product, launched by Rinrei Tape Co., Ltd. in August 2024, works with both plant and mineral oils, can be torn by hand, and can be written on—a magical tape. In manufacturing, oil is used on various parts and surfaces, but even in such environments, this special tape can adhere without peeling off when applied properly. Additionally, we introduce the clear anti-slip tape from the same manufacturer! This adhesive tape features a special adhesive that absorbs oil. It utilizes a strong adhesive design and a thick laminated high-strength substrate, eliminating the need for large-scale degreasing operations. In locations where oil is used, it is essential for tasks like marking lines or writing down NG spots on products coated with anti-rust oil, as well as for memo-taking. It is sure to become indispensable for production lines across various manufacturers. Can be applied directly to oily surfaces Exhibits strong adhesive power on surfaces with oil (compatible with both mineral and plant oils). No need for extensive degreasing work. *However, it is recommended to clean the surface beforehand if the floor is dirty. Easy to handle Tears by hand, with no release paper, improving work efficiency and reducing waste. Versatile for different scenarios Available in two colors (white and yellow) to meet various needs, such as fixing metal parts or using as line tape. Typically, adhesive tapes cannot be used on oily surfaces without thorough degreasing. Simply wiping oil with a cloth is not enough, and only after using a dedicated cleaner is the surface degreased. Additionally, there are cases where degreasing is prohibited, such as on metal processing products, resulting in many situations where adhesive tape cannot be used. The “Oil Surface Tape #6001L” released this time is a functional tape that can be used directly on oily surfaces without the need for degreasing. The adhesive used in this product is a special one that absorbs oil, and its adhesive strength develops within seconds after application. This product is also designed to be hand-torn straight, without the need for scissors or a cutter. Moreover, it is release-paper-free, ensuring no additional waste in the workplace. By using this product, it greatly contributes to improving work efficiency for those dealing with oily surfaces. ＜Detailed Catalog＞ *Only Japanese Ver. Click here for the catalog >> ＜Product ...

Choosing the right tool for the intended purpose is important! How to handle screws and bolts: Screws and bolts are crucial components that greatly affect the safety and durability of products. By choosing the right tools and mastering proper handling techniques, you can improve work efficiency and quality. Don’t forget to maintain your tools regularly to ensure they are in optimal condition, as this is the first step towards improving product quality. Screws and bolts may look similar, but they are different components. Generally, screws are used alone to fasten materials, while bolts are used together with nuts. Screws can be directly fixed into materials like wood, metal, or plastic, whereas bolts are often used with nuts and washers to secure machine parts or construction materials. Both screws and bolts consist of the “head,” “shaft,” and “thread.” The head is the part turned by a tool, and the shaft affects the length and strength. The pitch (spacing) of the threads determines the holding power, with finer threads offering higher fastening strength. Machine Screws: Used in home appliances and precision instruments. Tapping Screws: Can be screwed directly into wood or thin metal sheets, making them useful for furniture assembly and construction sites. Hex Bolts: Used for securing machinery and structures that require high clamping strength. ▼ Basic Knowledge of Screws and Bolts URL: https://ohtavn.com/en/about-dealings/basic-knowledge/ ▼ Thorough Explanation of Screw Types! How to Choose the Best for Your Manufacturing Site URL: https://ohtavn.com/en/media/screw-type/ Selecting the right tools for handling screws and bolts is essential for ensuring proper fastening. Here, we explain the main types of tools and their features. Driver Drivers are one of the most basic tools and are used to tighten or loosen screws with Phillips (+) or slotted (-) heads. Phillips Driver: Designed for Phillips screws, widely used in households and DIY projects. Selecting the right size driver is essential for securely turning screws. Slotted Driver: Used for slotted screws or certain specialized screws, often found in older products or construction sites. Hex Wrench (Allen Key) A hex wrench is used for tightening hex bolts or socket head bolts (commonly known as cap bolts). Hex wrenches are especially useful in tight spaces or for accessing hard-to-reach areas inside machinery. Additionally, they allow for applying significant torque, making them ideal for secure fastening. Torque Wrench A torque wrench is a tool used to tighten screws and bolts to a specified torque.

Explaining the different types of screws! How to choose the best one for your manufacturing site: In this article, we will explain in detail the various types of screws used in manufacturing sites and the key points for selecting them. Choose the optimal screws according to the application and material to improve work efficiency and safety. Screws are simple yet crucial parts used to securely fasten multiple components. A screw consists of three main elements: the head, shaft, and thread. Head: This is the part that is turned with a screwdriver or wrench. There are various shapes such as Phillips (+), slotted (-), hexagon, and star. Additionally, there are countersunk and round head shapes, which are selected depending on the application. Shaft: The shaft connects the head and the thread, and its length and strength affect the screw’s overall performance. The thickness and length of the shaft determine the holding force and load-bearing capacity. Thread: The thread is a spiral groove engraved along the outer circumference of the shaft. When turned, it bites into the target material, providing holding power. The pitch (spacing) of the thread varies depending on the application. A coarse pitch is suitable for quick tightening, while a fine pitch offers greater holding power. The most basic role of screws is to connect and securely fix multiple components. This function allows the firm connection of parts in all kinds of products, from buildings and machinery to electronics, ensuring stable performance over a long period. Screws, with their simplicity and high reusability, offer unique advantages over methods such as welding or riveting. The primary role of screws is to stably fasten parts or structures. As the threads bite into the material, they generate strong holding power, able to withstand external pressure and vibrations. Especially with screws, once fastened, objects can be kept safe for a long time. This makes screws indispensable in industries like construction, automotive, and aviation. Unlike other fastening methods (such as welding or adhesives), screws can be easily removed with tools, making the disassembly and maintenance of machinery or products simple. If upgrades or parts replacements are needed, components fastened with screws can be easily removed, allowing for smooth repairs and modifications. This characteristic also contributes to cost savings in manufacturing. In environments with vibrations or operating machinery, screw loosening can be a problem. Therefore, various loosening prevention techniques have been developed. For example, combining screws with washers or nylon nuts can prevent them from loosening naturally. Furthermore, some screws themselves ...
