Ceramic Locating Pins
Locating pins for Nut welding are produced with several different materials and several different coatings. Generally speaking, the more costly the pin, the “longer life” it has in production. As a long time distributor of resistance welding supplies, we stock commonly used pins at competitive prices.
Silicon Nitride Ceramic is typically used to make welding guide rolls for the high frequency ERW in continuous steel tube & aluminium tube production. Si3N4 is an excellent material solution in this application because of its following advantages:
| · Flexural strength | · Chemical resistance | · Electrical insulation | · Corrosion resistance | · Dielectric strength |
| · Wear resistance | · Temperature resistance | · Thermal conductivity | · High voltage | · Hardness... |
Location And Resistance Weld Centering Pins
The heat-resistant and non-conductive ceramic pin materials help achieve consistency over hundreds of thousands or millions of welds, without the need for constant downtime and replacement.
The weld pins are available in three standard noses, for automatic feeders or hand-fed applications, with standard diameters to 0.1 mm stamping hole diameter.

Small Head Pins
Small head locating pins are typically smaller than the pin's shoulder, which is 22 or 25mm in diameter. The NAAMS Standards pin diameter sizes for small heads are 6mm, 8mm, 10mm, 12mm, 13mm, 16mm, and 19mm. |
 |
Large Head Pins Large head locating pins have heads wider than the insert bases which is a diameter of 15.98mm. The standard sizes for large heads are offered in 25mm, 30mm, 35mm, and 40mm. |
 |
Retractable Pins All retractable pins come with a slotted hole meant for an 8mm socket head shoulder screw assembly. The standard offerings are the same as the small heads and large heads but retractable locating pins do not come with shoulders because of the added slot and hole configuration. |
 |
Bullet Nose Pins, Diamond Pins, and Cone Pins Bullet nose and cone pins come as 4-way and 2-way pins like diamond pins. They work as 4-way pins by restricting the motion from 2 different axis, stopping the located part in 4 separate directions. This helps to keep your workpieces in place during the automation or manufacturing process. As 2-way pins, they come with two slits and the diamond pins come with a diamond shaped head. This limits the free motion to only 1 axis or 2 degrees of movement. Using a configuration of both 2 and 4-way pins help to hold workpieces in the desired place. |
 |
Round and Sphere Pins Round and sphere pins are the most common and come as a 4-way. Though they are most common, they can present problems suck as binding the workpiece. It is recommended to use them in conjunction with 2-way pins. |
