PCB Eyelets
Ever wonder how components on a circuit board stay connected from top to bottom? Often, it's a tiny metal ring called a PCB eyelet. At Nuote Metals, we make these precision components for electronics manufacturers who need reliable, consistent through-board connections.
A PCB eyelet is a small, hollow tube, usually brass or copper, that gets inserted into a drilled hole on a circuit board . Once in place, the ends are flared or "set" to create a permanent, conductive pathway between layers . They serve two main purposes: mechanical reinforcement and electrical connection .
Before plated-through holes became common, eyelets were the only way to make reliable connections on double-sided boards . They prevent the copper foil from peeling during soldering or repair work. Even today, they're used in high-current applications, power supplies, and boards that need extra durability .
Why choose Nuote Metals for PCB eyelets? Because precision matters in electronics. A poorly made eyelet can cause intermittent connections or solder failures that are nearly impossible to track down . We make ours with consistent inside diameters, clean barrel lengths, and the right plating—usually tin over brass or copper—to ensure good solderability and long-term reliability .
We produce PCB eyelets in standard sizes like 1mm, 2mm, and 3mm diameters, and we can customize lengths to match your board thickness. Materials include brass for general use, copper for maximum conductivity, and tin-plated options for easy soldering .
If your circuit boards need tough, reliable through-hole connections, our PCB eyelets are built for the job. At Nuote Metals, we keep quality consistent so your boards stay connected—batch after batch.

Stamped Brackets
We are Nuote Metals in Dongguan. Our shop makes stamped brackets every day. Stamped brackets are those L-shaped or U-shaped metal pieces that hold things together. We stamp them from steel sheets, aluminum sheets, or sometimes brass. Stamped brackets need to be strong and straight. We bend them at exact angles so they fit right. Each batch of stamped brackets gets checked for proper bends and hole positions. Customers order our stamped brackets when they need reliable mounting parts. We can make samples first to ensure they match your needs.
Deep Drawn Metal Stamping
Here at Nuote Metals in Dongguan, we do deep drawn metal stamping . This is how we make deep metal cups, tubes, and cases in one piece. Regular stamping can't make such deep shapes. Deep drawn metal stamping pulls the metal down into a die, like stretching dough. We do this step by step until we get the right depth. Each deep drawn metal stamping job needs good tools and careful handling. Our workers check the parts as they come out. They measure the walls and look for smooth surfaces. Customers come to us when they need seamless deep parts. We make samples first so you can see if they work.
Truss Head Half Tubular Rivets
For a broad, low-profile fastening solution, Nuote Metals from China offers Custom truss head half tubular rivets. The wide head distributes pressure evenly, preventing pull-through on soft materials like plastic, leather, or thin sheet metal. Ideal for automotive interiors, luggage, and electrical enclosures. The half-tubular design sets quickly with minimal force, saving assembly time. Available in multiple materials. Solve surface damage and weak holds. Trust our factory for precision rivets that deliver reliable, lasting results.
Countersunk Head Semi Hollow Rivets
Why choose countersunk head semi hollow rivets instead of other connection methods? This is primarily due to their unique advantages. After installation, the head is flush with the surface, avoiding potential interference or safety hazards caused by protrusions. The semi-hollow design makes the riveting process relatively simple, requiring no complex equipment; it can usually be completed manually or with pneumatic tools. This type of rivet is suitable for materials of varying thicknesses, and can be adapted to various situations by adjusting the riveting force.
Brass Pan Head Rivets
Nuote Metals specializes in the production of brass pan head rivets. Our rivets are made of H65 brass, which has a high brass content, is soft and easily formed, and is less likely to crack during the riveting process. Brass pan head rivets consist of a head and a shank, with the shank being hollow for approximately half its length. During installation, the rivet is inserted into a pre-drilled hole. Using a specialized riveting machine and punch, the end of the shank expands and forms the head on the other side, creating a clamping connection. This process relies on plastic deformation of the metal, eliminating the need for welding or adhesives, making it simple and efficient.
Pan Head Solid Rivets
Nuote Metals is a pan head solid rivets manufacturer in China, we have more than 10 years’ working experience in metal rivets, a pan head solid rivet a type of rivet with a flat and wide head . We have various sizes of rivets in stock, materials can be brass, copper, stainless steel, carbon steel, aluminum etc.
