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, as well as the design performance of the equipment.

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 shank length of 1,000 mm). Compacting of devices. Improvement of equipment design performance. Application in narrow spaces and enhanced workability. Increased reliability due to prevention of loosening with high tightening force. *For urgent or emergency cases, or for technical inquiries, please contact us directly through our website.*
