Stainless Steel Carbon Steel Black Oxide Pins Dowel Pin Cylindrical Pin Straight Pin

Dowels (wood dowels/wood pins) are specialized fasteners specifically designed for woodwork connections and positioning. They are made from high-quality solid wood (such as pine, birch, oak, etc.) or high-density boards. They are in a standard cylindrical shape, with smooth surfaces free of burrs and precise dimensions. They can be used with glue to achieve a tight connection and precise positioning of wooden components. No additional drilling or tapping is required. Installation is convenient and highly concealed, without damaging the aesthetic appearance of the base material. The products undergo meticulous processing such as drying and sanding, which makes them resistant to deformation and cracking. They have excellent toughness, strong connection, strong adaptability, and are environmentally friendly with no unpleasant odor. The specifications range from 3mm to 20mm in regular diameter, and the length can be customized as needed, suitable for connecting different thicknesses and materials of wooden substrates.

Structural form: It is divided into solid cylindrical pins and hollow cylindrical pins. The solid pins have stronger load-bearing capacity, while the hollow pins are more lightweight and easier to disassemble. The ends are mostly designed as chamfers or arcs, which facilitate the guiding installation.

Material properties: The core materials include 40Cr, 45# steel, and 304/316 stainless steel, etc. The alloy steel models have high strength and good toughness, while the stainless steel models have outstanding corrosion resistance. You can choose flexibly according to the usage environment.

Precision standards: Strictly follow GB/T 119, ISO 2338, etc. standards for production. The surface roughness is low, the size consistency is good, and it can achieve interference fit or transitional fit to ensure the stability of the connection.

Appearance distinction: The surface presents metallic silver-gray or black. The solid pins have a full cylindrical solid structure, and the end of the hollow pins shows an internal hole, which facilitates quick identification of the model and purpose on-site.

High positioning accuracy: Both the cylindrical surface and the end face have undergone precise grinding processing. The coaxiality and dimensional tolerance are controlled at the micrometer level, ensuring the repeat positioning accuracy of the connected components and meeting the assembly requirements of precision equipment.

Strong shear resistance: The solid pins are made of high-strength alloy steel and undergo quenching treatment, which gives them excellent shear resistance and compression resistance. They can withstand large lateral loads and prevent connection failure.

Easy installation and disassembly: Some models adopt hollow structures or chamfered designs, and with the help of special tools, they can be quickly assembled and disassembled. At the same time, they are convenient for later maintenance and component replacement, reducing operation and maintenance costs.

Corrosion-resistant, wear-resistant and durable: Optional stainless steel materials or surface hardening, blackening, galvanization and other treatment processes can be selected. They can maintain stable performance in humid, corrosive or high-maintenance environments, extending the product's service life.

Wide adaptability: Multiple specifications of diameters, lengths and solid/hollow models are available for selection. They can be compatible with different materials and thicknesses of components for assembly, meeting the diverse industrial scene requirements.

Precision mechanical manufacturing: Components positioning and shaft connection for machine tools, automation equipment, and instruments and meters, ensuring transmission accuracy and operational stability.

Molds and tooling fixtures: In injection molds, stamping molds, and tooling fixtures, as positioning pins to achieve precise alignment of mold cavities and inserts, improving product forming accuracy and production efficiency.

Automobile and construction machinery: Applied to components of engines, transmissions, chassis, and construction machinery frames for locking and positioning, capable of withstanding vibration and impact loads, ensuring equipment operation safety.

Electronic and electrical equipment: Small-sized cylindrical pins for positioning and fixation of precision electronic components and connectors, meeting requirements for miniaturization and high-precision assembly.

Steel structures and hardware assembly: As connecting pins in furniture, doors and windows, and steel structure supports, achieving hinge or fixation between components, combining strength and assembly flexibility.

It is widely used in scenarios such as the assembly of solid wood furniture, the splicing of panel-style furniture, woodworking craftsmanship production, the reinforcement of home decoration woodwork, the processing of wooden handicrafts, the splicing of cabinets and wardrobes, and the assembly of wooden doors. Its main feature is the use of dedicated connection and positioning for wooden substrates. It can not only achieve precise alignment of components, but also enhance the firmness of the connection parts, replacing traditional iron nails. It combines aesthetics with practicality and is an indispensable special accessory in furniture manufacturing, woodworking processing, and home decoration woodwork. It can be customized in terms of diameter, length and material as needed to meet the customized requirements of different scenarios.

Q1: Can I install your anchor bolts in pre-existing concrete structures?

A: In many cases, it is possible to install our anchor bolts in pre-existing concrete structures. However, the process may require special techniques such as drilling and using chemical anchors or expansion anchors in some cases. It is important to assess the condition of the existing concrete and consult with a professional or our technical team to determine the best installation method.

Q2: How do I select the right size of anchor bolt for my project?

A: Selecting the right size of anchor bolt depends on several factors, including the type of structure, the load it will bear, and the characteristics of the base material. You should consider the tensile and shear forces that the bolt will be subjected to and refer to our product specifications and engineering guidelines. Our sales team can also assist you in choosing the appropriate size based on your project requirements.

Q3: What is the difference between a chemical anchor bolt and a mechanical anchor bolt?

A: A chemical anchor bolt uses a chemical adhesive to bond the bolt to the base material, providing a strong connection. It is often used in situations where a high level of precision and load-bearing capacity is required. A mechanical anchor bolt, on the other hand, relies on mechanical means such as expansion or friction to secure the bolt in place. The choice between the two depends on factors such as the type of base material, the application requirements, and the environmental conditions.

Q4: Do your anchor bolts come with any warranty?

A: Yes, we offer a warranty on our anchor bolts. The specific terms and conditions of the warranty may vary depending on the product and the application. Please refer to our warranty policy or contact our customer service team for more information.
