(1)The mutter nut combination satisfies the strict requirements of thickness from SACHS through our self-developed, innovative cold forging process. Our products provide higher specifications for the surface roughness, flatness and thickness of nuts to optimize the damper’s noise emissions and bring a clear increase in driving comfort.
(2)The nuts meet the requirements of the assembly of shock absorber piston valves from SACHS, including anti-loosening, working in the oil and a low friction coefficient. In addition, the thread forming of the nut and bolt adopt tapping-difference design (1.0mm vs 0.95mm) to make closer contact with each other and further to increase the maximum torque value.
(3)The traditional lathe process is replaced by a cold forging method that efficiently increases output of finished nuts by dozens of times. Moreover, the waste of raw materials and additional processing costs are reduced significantly.

Jing-Fong is the ancestor of lock nuts production in Taiwan since 1950. The initial products are engineered standard fasteners for various industries. Facing the competitions from China, we realized that products need to be upgraded with the positions of high skill, high added value and high quality to avoid price competition from red supply chain. In 2000, Jing-Fong established the first overseas manufacturing plant in Thailand to implement the strategies of global localization production and International Division of Labor. Through strategic alliance with Germany auto companies, we successfully introduced lock nuts to the supply chain of new car assembly as Tier-1 supplier, including Mercedes Benz, BMW and other global auto manufacturers. The overall margin profit also showed a leap-forward growth. At present, Jing-Fong is the largest supplier of lock nuts in Daimler AG's global assembly plant, and the main supplier of key fasteners for various ZF SACHS vehicle shock absorbers.
