Product Introduction

The connection principle of lock-bolt is using riveting tool to swage the collar metal into the grooves to complete permanent connection. Compared with other types of fastening connection, lock-bolt has advantages of high connection strength, good reliability, superior vibration resistance, outstanding fatigue resistance, convenient installation, maintenance-free, etc. After the special surface treatment, lock-bolt has excellent corrosion resistance and can be used for connection between different material (aluminum and steel, aluminum and aluminum, etc.).

Product Advantage

① High connection strength
② Superior vibration resistance
③ Good reliability
④ Outstanding fatigue resistance
⑤ Convenient installation
⑥ Maintenance-free

Product Parameters

① Basic dimension of rivet
