Hexagon socket bolts (caps) for large machinery, civil engineering, and shipbuilding-related products.

Hexagon socket bolts (caps) for large machinery, civil engineering, and shipbuilding-related products.

The compactness of the device has improved, and the design performance of the equipment has enhanced.

Hexagon socket head bolts are generally used without nuts, so the term "screw" is more accurate. However, since the name "hexagon socket bolt" has become widespread, they are also referred to as cap bolts. The applicable strength grades are 8.8, 10.9, and 12.9. They are tightened with a hexagon rod wrench (with a maximum neck length of 1,000 mm). This contributes to the compactness of the equipment, improves the design performance of the devices, allows for application in narrow spaces, and enhances workability. With high tightening force, it improves reliability by preventing loosening. *For urgent or emergency inquiries, or technical questions, please contact us directly through our website.

Unique screw-shaped tapping bolt "Sure Twist"

Unique screw-shaped tapping bolt "Sure Twist"

This is a tapping type one-sided bolt with a unique screw shape that firmly adheres to the base material, providing high joint strength. There is also a thicker diameter of φ16mm available.

The Shuatsu Twist is a tapping-type one-sided bolt that forms female threads by plastically deforming the base material (steel plate) with its unique screw shape. Due to its low thread height (0.41mm), it produces almost no chips compared to standard products. Additionally, because the threads are concentric, they embed into the fastening material all around the bolt, achieving high strength, vibration resistance, and water tightness. It is used as a method for joining steel materials as an alternative to welding.
