JY patented flat head screw
JY patented flat head screw utilizes the most advanced materials and manufacturing technology to ensure its stability and durability. This screw can withstand high loads and strong torque, and has excellent anti-loosening ability, providing long-term stable connections for your products.
Choosing JY's patented flat head screw can reduce risks, increase safety in use, extend the equipment's service life, and reduce maintenance costs. It also saves time for maintenance and replacement of screws, and increases customer confidence in the quality and stability of the equipment, thereby improving the product's reputation and satisfaction.
1.Working with the manufacturer: JinYuan Industrial Co., Ltd.
Product: JY patented flat head screw, various hexagonal screws, stainless steel composite,self-tapping screw, composite cement anchor bolt, expansion mesh, wire duct, safety cable.
2.Patent number: Taiwan M540258 / China ZL201621356025.6.
JY patented flat head screws are compatible with Taiwan's Nylok anti-loosening adhesive, which meets NASA and the American Tool Association's IFI-524 certification standards.
3.IFI-524 Strength and torque certification
4.Anti-loosening certification test
A.Experimental design
-
Experimental Design:The objective of the experiment is to test the difference in anti-loosening performance between two types of screws, one coated with NYLOK anti-loosening agent and the other without, when subjected to high-frequency vibration at 1780rpm.
-
Screw specification: M81.2560 square head (semi-thread)
-
Vibration cycles: 30,000 cycles
-
Methodology: Both the screws coated with NYLOK anti-loosening agent and the screws without coating will be locked with nuts and subjected to vibration testing simultaneously.
B.Experimental Process and Results
1.The experiment begins.
3.Vibration test started
5.The experiment concluded with the NYLOK-coated screw on the right passing the 30,000 vibration test with the black line remaining straight.
2.The left side is without NYLOK coating, and the right side is coated with NYLOK.
4.The left screw without NYLOK coating fell off at the 1684th vibration, demonstrating the importance of anti-loosening function.
6.Experiment ended and the counter indicates that the screw has passed the anti-loosening specification (30,000 cycles).
C.Experimental Results
After conducting vibration testing in accordance with the international vibration testing standard (IFI-524), it was found that the uncoated screws detached after 1,684 vibrations, while the screws coated with NYLOK anti-loosening agent passed over 30,000 vibrations with no signs of loosening.
This experiment proves that the performance of the Taiwan-made NYLOK anti-loosening agent used by JY's collaborative manufacturers meets the requirements of the solar energy industry. The JY patented flat head screws, which have multiple certifications, along with their compatibility with the NYLOK anti-loosening agent, demonstrate an effectiveness that is beyond that of standard screws.
5. Comparison of Salt Spray Test (500 hours) for Screws
The white iron screws exhibited severe corrosion.
The JY 316 screw showed minimal signs of corrosion.
Partial corrosion was observed on the Chinese-made 302 screws.
