We would like to introduce a case study on the development of fasteners proposed by Yamaki Sangyo for securing cement flat roof materials to fire-resistant sheathing. The customer's request was to secure the roofing materials to the fire-resistant sheathing. Since the substrate is made of inorganic material rather than fibrous material, there was a significant issue with fasteners being prone to loosening, and there was concern that if the heads of the fasteners were not flat, the roofing materials would crack when walked on. Therefore, we proposed using screws instead of nails. Additionally, we used a special flexible material with grooves in the countersunk part of the screw to ensure that the screw heads would not protrude above the surface. Through these innovations, we were able to propose screws that meet the customer's requirements. 【Case Study】 ■ Issues - Fasteners are very prone to loosening when secured to inorganic substrates. - If the heads are not flat, roofing materials may crack when walked on. ■ Proposal - Use screws instead of nails. - Use a special flexible material with grooves in the countersunk part of the screw to ensure the screw heads are flush with the material. *For more details, please refer to the PDF document or feel free to contact us.

Our company offers a variety of cleverly designed fasteners. The "Namiitabisu" is used to secure corrugated sheets made of reinforced plastic (polycarbonate) to aluminum or steel frameworks. The screw itself is equipped with a stopper that matches the height of the corrugated sheet's waves, designed to prevent leaks caused by insufficient driving or deformation of the washer and corrugated sheet due to excessive driving. In addition, we have developed various products such as the "Bestreamabis," used for securing fire-resistant sheathing to C-shaped steel, and "Double Head Nails," used for temporary fastening. 【Features of Namiitabisu】 ■ A stopper on the screw that matches the height of the corrugated sheet's waves ■ A design that prevents leaks caused by insufficient driving ■ A design that prevents leaks caused by deformation of the washer and corrugated sheet due to excessive driving *For more details, please refer to the PDF document or feel free to contact us.

Screws and nails are important not only for their functionality but also for their appearance. When considering the finish of screws and nails, the key points are "surface treatment" and "shape." By applying surface treatment (such as painting) mainly to the heads of screws and nails, their appearance can be improved, or by matching the color with the material, the heads of the screws and nails can be made less noticeable. Conversely, there are cases where items like decorative nails, tacks, and chrysanthemum nails are used to stand out (by adding decorations). [Key Points] ■ Surface Treatment ■ Shape *For more details, please refer to the PDF document or feel free to contact us.

• Safety and consumables

When fastening screws or nails to objects subjected to shear forces, it is necessary to use high-strength ones. Two points for selecting strong screws and nails are "shape" and "material/surface treatment." To increase strength, one can simply use thicker screws or nails, but it is essential to consider various conditions, such as situations where it may not be possible to use thicker ones due to the nature of the site. [Points to Improve Work Efficiency] ■ Connection ■ Shape *For more details, please refer to the PDF document or feel free to contact us.

• Safety and consumables

Corrosion resistance is a very important point in the selection of screws and nails. One method to enhance corrosion resistance is surface treatment. Surface treatments include electroplating, where metal is electrolyzed and deposited on the surface; hot-dip galvanizing, where metal is melted and coated like a garment; and painting, where resin or metal powder is applied. In addition, material and galvanic corrosion are also key points in selecting screws and nails with high corrosion resistance. **Points for Selecting Corrosion-Resistant Screws and Nails** - Surface treatment - Material - Galvanic corrosion *For more details, please refer to the PDF document or feel free to contact us.*

• Safety and consumables

To improve work efficiency, it is necessary to consider various factors for each site where fasteners (screws, nails) are used, ensuring that tasks can be performed easily, quickly, and with one less step, depending on the objectives. The two key points for enhancing work efficiency are "connection" and "shape." Even with the same screws or nails, connecting them and using a machine for installation allows for one-handed operation, rather than manually hammering or tightening them individually. Additionally, there are methods to make the product's body shape less prone to disengagement through processing. [Points for Improving Work Efficiency] ■ Connection ■ Shape *For more details, please refer to the PDF document or feel free to contact us.

• Safety and consumables

When using screws or nails in conditions where they are likely to come loose, it is especially important to pay attention to holding power. There are three key points to maintain holding power: "surface treatment," "shape," and "special products." One method is to apply a special chemical to the surface of the product, which acts as an adhesive to prevent loosening and slipping. Another method involves altering the shape of the product's body to make it less likely to come loose. Additionally, there are methods that combine the product with other materials or shapes to achieve a loosening prevention effect. [Key Points for Maintaining Holding Power] ■ Surface Treatment ■ Shape ■ Special Products *For more details, please refer to the PDF document or feel free to contact us.
