Quarter-Turn Retainer, Size 6, 65Mn&Internal Tooth Starlock Star Lock Locking Washers

Toothed star lock washer fastening requirements also include the following aspects:
1. The tooth structure of the washer is required to be clearly defined with uniform tooth spacing. This ensures that the toothed washer can bite closely to the part during assembly and provide sufficient friction. At the same time, the uniform distribution of tooth spacing can also ensure that the fixing force is evenly distributed to avoid over-tightening or localized loosening.
2. The teeth of the washer are required to have smooth edges without burrs or sharp corners. This avoids scratching or damaging the surface of the part during assembly and ensures that the toothed washer can enter the part hole smoothly.
3. Requirements for the material of the gasket have good corrosion and wear resistance. Mechanical equipment is often used in harsh environmental conditions, such as high temperature, high humidity, corrosive media, etc., toothed star washers need to be able to maintain their performance and be fixed for a long time.
4. Toothed internal star washers are easy and quick to install and dismantle, and do not cause too much trouble for the maintenance and repair of mechanical equipment. This can improve the reliability and maintainability of the equipment, and reduce maintenance time and cost.    

As a commonly used fastening element, the toothed internal star lock washer has an important role in mechanical equipment. It can provide a certain fixing force through a special structure and working principle to ensure the fastening and fixing effect of parts. In the process of use, attention needs to be paid to the selection of appropriate specifications and sizes, to ensure that the tooth structure is clear and precise, the uniform distribution of tooth spacing, the edge the smooth and burr-free, the material corrosion and abrasion resistance, as well as the convenience of installation and dismantling. Through the reasonable selection and use of a tooth-shaped inner star lock washer, you can improve the stability and reliability of mechanical equipment, reduce the number of failures and maintenance, and extend the service life of the equipment.    

Metric Internal-Tooth Lock Washers， Internal teeth dig into the screw head while the smooth outside edge won't snag objects. These washers provide greater vibration resistance than split lock washers. Use with fasteners that have small heads, such as fillister and cheese head screws.
Black-oxide steel washers are mildly corrosion-resistant in dry environments.
Zinc-plated steel washers resist corrosion in wet environments.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
