Basic Description
Stainless steel and ceramics typically have been used for manufacturing nut locator pins. However, stainless steel, while durable, has the disadvantage of requiring an insulator between the pin and the electrode. Weld heat and grease quickly break down the insulator and the locator pin is subject to electrical arcing across the electrode. Ceramic, in general, is too brittle and pin breakage is a problem.

Dengensha America Corp., in an effort to provide our customers with the very best products, searched for the best technology available and found a superior material called ACT to replace the existing trouble-prone locator pin systems. ACT utilizes a proprietary coating developed specifically to withstand the combination of high current and pressure found in nut welding applications.

ACT alloy pins are made from a relatively new material with a special insulating surface. This innovative surface allows the pinto be used without additional insulation from the electrode when locating weld nuts for projection welding. ACT is extremely cost effective. Customer cost studies have proven that ACT outlasts KCF and ceramic coated pins by nearly two to one, and is far less expensive then ceramic composition pins, providing the user with the lowest possible cost per nut weld. While there are many similar looking locator pins available in the market none of the “knock offs” provide the exceptional wear capabilities and high reliability you can expect from Dengensha’s ACT Alloy Nut Locator Pins. As a result our locator pins have become the “Pin of Choice” for thousands of welding manufacturers worldwide.
