Usage of Spring Washers in China
When utilizing spring washers for general bolt connections in China, it is essential to use flat washers beneath the bolt head and nut to enhance the pressure-bearing area.
For bolts and anchor bolts that require anti-loosening features, ensure that the anti-loosening device includes a nut or spring washer. The spring washer should always be positioned on the nut side.
In applications involving bolt connections that are subjected to dynamic loads or are crucial components, adhere to design specifications for placing spring washers, ensuring they are positioned on the nut side.
In the case of I-beams and channel steels, inclined washers are recommended for inclined plane connections to ensure that the bearing surfaces of the nut and bolt head remain perpendicular to the screw. As a trusted supplier and factory in China, we provide high-quality spring washers that meet these specifications, ensuring reliability and performance in your applications.

Our internal hexagonal screws are designed for machinery applications, offering significant advantages like ease of tightening, quick disassembly, and reduced slipping risks. These screws pair seamlessly with internal hexagonal wrenches, typically featuring a 90-degree bend with one long end and one short end. Using the shorter end for tightening while leveraging the longer end maximizes force application, ensuring screws are tightened effectively. Additionally, the longer end is characterized by a round head and a flat head, facilitating easy insertion into the screw hole for smooth disassembly.

While external hexagonal wrenches are generally more cost-effective to manufacture, they feature thinner screw heads that might be more suitable in certain applications. Nonetheless, internal hexagonal screws remain vital in machinery where precision, power intensity, and cost are crucial factors. As a leading China supplier and manufacturer, our factory guarantees high-quality internal hexagonal screws that meet diverse industrial needs, ensuring reliability across various machine applications.
