We specialize in developing high quality fastener products,a global leader in the design,manufacturing and implementation of engineered fasteners. And our latest patented technology, No Loose Nuts or No Loose Studs, has a very obvious advantage of loosening resistance, which will bring great convenience and advantage to your business.We serve a variety of industries, including building & construction, heavy truck, rail, agriculture, automotive, and aersopace.

Our no-loose nuts or no-loose studs use a special thread-grain joint anti-loosening technology with dual nut anti-loosening that ensures that the fastener will not loosen due to vibration or other causes.

We recently did the transverse vibration test in accordance with ISO16130-2015, 10.9 grade nut M16x2, preload force of about 100kN, sine wave, the same pair of nuts in two consecutive tests, each vibration 30,000 times, a total of 60,000 times after vibration, the amount of preload force drop is 0%. There is no relative position misalignment between the nut and the screw. This experiment fully demonstrates the anti-loosening reliability of our nuts and the ability to be disassembled and reused for easy maintenance.

We know that automobiles, rail engineering, power grids, aerospace, ships, bridges, oil wells, excavation, precision instruments, mechanical equipment with vibration conditions, etc. have very high requirements for fasteners because they must withstand high intensity vibration and harsh environmental conditions. Our non-loosening nuts or non-loosening studs are designed to meet these requirements, ensuring long-term reliable tightening of the parts to be fastened, and reducing the number of repairs and maintenance costs.
