Petal expansion bolt
working principle
The basic working principle of expansion bolts is to use the interaction between the expansion cylinder and the screw to achieve fastening. When the nut is tightened, the screw moves outward, causing the conical part to move through the axial movement of the thread, thereby squeezing the expansion cylinder, causing it to expand and fill the hole, thus achieving the purpose of firm fixation.
Specifications and materials
The specifications of petal expansion bolts are diverse, with common models such as M425 and M525, and lengths ranging from 10mm to 30mm. The material is usually 304 stainless steel or plain carbon steel, and the surface treatment is mostly galvanized to improve corrosion resistance.
