Expansion Bolts for Elevator are specially developed type of expansion bolts for elevator installation. Their extremely strong strength and great carrying capacity make the elevator safely and stably operate in different conditions. Elevator expansion bolts are carefully manufactured by excellent metal materials and finely heat treated. They have good pulling, shearing and fatigue resistance. Their fastening performance is reliable and wide application range.

In the field of high-end equipment manufacturing, the weight and strength of a single screw often determine the performance limit of the entire machine. When traditional stainless steel screws are difficult to break through due to weight and corrosion resistance bottlenecks, titanium hexagonal socket head screws are becoming the preferred fastening solution for industries such as aerospace and precision electronics due to their disruptive advantages of light weight and high strength.

The biggest feature of Round Head Screw is its "triple combination" design, which is usually composed of screws, flat washers, and spring washers. This integrated design brings many advantages. During the installation process, there is no need to separately search for and install gaskets, greatly saving installation time and labor costs. For large-scale production enterprises, this convenience means a significant improvement in production efficiency.

Special Torx drive shape: The star-shaped slot in the screw head is also equipped with a Torx drive. The star-shaped recess engages better with matching driver screws and ensures evenly distributed applied force when tightening/loosening, thus avoiding cam-out occurrences and greatly enhancing operational smoothness and efficiency. Film has a uniformly glossy finish as plated with zinc. Drive system optimized sequence drive system, which provides perfectly balanced torque.

Titanium, a magical element known as the "space metal" and "ocean metal", gives titanium screws unparalleled advantages. The density of titanium is only 57% of steel, which means that titanium screws can significantly reduce weight while ensuring strength. For fields such as aerospace and racing that are highly sensitive to weight, using titanium screws can effectively reduce overall weight and improve energy efficiency.

Titanium Alloy Hex Head Screws are quenched and tempered with titanium alloy material which has great lightweight resistance, strength and corrosion resistance. And the hex head outside can be driven to quickly install and remove. Titanium alloy machine screw is widely used in aerospace, shipbuilding, medical equipment, high quality automobile etc for more durable structure and longer life.
