At Rugao Tongcheng Stamping Machinery Manufacturing we produce the Lock washer as part of our trailer accessory and axle assembly range. The product page lists the item under Trailer accessories and presents the company as a manufacturer of trailer axle components, automotive steering gear parts, metal stampings, precision machined parts and springs. The page also names long-term supply partnerships with several domestic enterprises and exports to Europe, Latin America and North America. In this article we describe the washer, the production range, the applications and the points a buyer should confirm before an order.
The Lock Washer in the Trailer Accessory Range
The page lists the product as a Lock washer in the Trailer accessories group. A lock washer is used under a nut or a bolt head to help keep a fastener tight in a vibrating assembly, and the material, the hardness, the inner diameter and the thickness are the critical points. The buyer should confirm the drawing, the steel grade, the hardness, the surface treatment, the inner and outer diameter and the thickness, because the page gives the product name and the category but not a dimension table. A sample washer and a dimensional report are the practical way to check the fit before the order.
Production Range and Capabilities
The page presents a product range that covers axle assembly parts, stamping parts, finished parts, trailer accessories and prestressed concrete pile accessories. The company primary products include trailer axle components, automotive steering gear parts, a wide range of metal stampings, precision machined parts and springs. That range means a buyer can source the washer together with related axle and trailer hardware from one factory. The buyer should confirm which process is used for the washer, such as stamping, hardening or a coating, and should ask for the drawing and the inspection plan for the part.
Applications and Buyer Checklist
The washer should be made from a steel grade that suits the joint. A carbon steel washer with a zinc, phosphate or Ruspert coating is common for a trailer part, while a stainless grade may be chosen for a wet or coastal application. The buyer should confirm the hardness range and the coating thickness and should check that the washer is flat and free of burrs. A burr or a bend can affect the torque and the contact area, so the inspection should include the flatness and the edge condition.
A lock washer is used on a truck, a trailer or an axle assembly where a bolted joint has to resist vibration. The buyer should confirm the load, the bolt size, the torque, the corrosion environment and the installation space before the order. The buyer should also confirm the hardness, the spring action and the coating, because a washer that is too soft or too hard may not hold the joint as intended. The page does not list a price, a minimum order quantity or a delivery lead time for this washer, so those points should be requested with a quotation.

The page states that the company has established long-term supply partnerships with Jianhua Building Materials Group, Jiangsu Overseas Group, Guangzhou Huajin, Guangzhou Tainade, Zhenjiang Baohua, Shanghai CaiChen, Jinan Fuhua Ruida and Shijiazhuang Ludi Ding, and that its products are exported to Europe, Latin America and North America.

For an order, the buyer should send the drawing, the material, the quantity and the destination so that the supplier can confirm the price, the tooling and the delivery schedule.
The Lock washer described above is therefore a trailer accessory in a range that also covers axle components, steering gear parts, machined parts and springs. The page gives the category and the company background, while the drawing and the hardness should be confirmed for the application. A sample and a dimensional report are the clearest way to approve the washer before the order.
