High Tensile Spring Washer
We take an M10 size as an example. We press the washer flat. It still gives at least 150 N of recovery force. We also did a transverse vibration test. It follows the ISO 16130 standard. The residual clamp force goes up by more than 35% compared to no washer. Our hardness is HRC 40-50. This meets the GB/T 94.1 standard.
Stop Nuts from Loosening with Our Spring Washer
Do your nuts come loose by themselves? Do screws run away when the machine shakes? This is a big headache. Our High Tensile Spring Washer solves this problem. It uses its own elastic deformation. It creates a steady counter-pressure after you tighten the bolt. It works like an invisible hand. It pushes against the nut all the time. We are a Shanghai factory with 20 years of experience.
Check Our Test Data and Material Choices
We take an M10 size as an example. We press the washer flat. It still gives at least 150 N of recovery force. We also did a transverse vibration test. It follows the ISO 16130 standard. The residual clamp force goes up by more than 35% compared to no washer. Our hardness is HRC 40-50. This meets the GB/T 94.1 standard. We offer three materials. 65MN spring steel has an elastic limit ≥800 MPa. Stainless steel SUS304 or SUS316 works for wet places. Carbon steel suits one-time assembly or low-load jobs. Surface finish includes black oxide, cleaning, or zinc plating. Zinc plating comes in white, blue-white, or yellow. Salt spray test lasts 72 hours with no red rust.

Why Our R&D and Fast Delivery Help You
We have our own R&D team. You can share your special needs. We will help solve your technical problems. Free samples are ready for stock items. Mass production takes 2-3 weeks for standard parts. Custom products take 4 weeks. Repeat orders are even faster. The elongation rate for 65MN is ≥10%. So the washer will not crack during installation. It works with regular bolts, high-strength bolts, and stainless steel bolts. You do not need to change your tools.
The entire product line is fully customizable.
