K-Wires

A Kirschner Wire, also known as K-Wire, is a smooth or threaded stainless steel or nitinol pin with a drill tip. Modern Grinding can manufacture K-Wires to your custom specification.

Custom K-Wires

Our K-Wires are available in different diameters from .018" to .178", lengths from .25" to 40" and an assortment of tips such as trocar tip K-Wires and diamond tip K-Wires. We have stainless steel and nitinol in stock but can also grind a variety of different materials. K-Wire is used mainly in orthopedic surgery and plastic surgery, to help hold bones in place. It is similar to Steinmann Pins but with smaller diameters. The typical K-Wire tip is 15 degrees from the angle to the center line. We can custom manufacture k-wire tip angles and add relief angles.

K-Wire Manufacturer

Modern Grinding has made custom research K-Wires for Universities like Harvard and Johns Hopkins as well as some of the largest orthopedic OEMs in the country. Whether you need 10 K-wires for research or an FDA application or 10,000 K-wires for a global product release, Modern Grinding can help. Due to our specialized machinery we are able to hold tight tolerances (.0001" and less) according to customer specifications. Our CNC machinery allows for high machining repeatability.

Stock K-Wires

Due to the large number of K-Wires we produce we have most standard sizes of stainless steel 316LVM wire in stock. We have a small but growing stock of nitinol wire as well. This allows us to provide a shorter manufacturing lead time and lower cost than most of our competitors.

Finishing

After we have made the threads, tips and cut to length, often we will electropolish, passivate and/or laser mark the k-wires. Electropolishing gives K-Wires a nice bright shine which looks great for your customers. Laser marking K-Wires allows you to add depth markers or part numbers. Passivation of stainless steel K-Wires allows you to adhere to ASTM A967 if that is a requirement that you need to meet.

K-Wire Fixation

K-Wires are typically used in orthopedic surgery for the fixation of bone fractures. K-Wires are often driven into the bone through the skin. Modern Grinding is a member of NASS (North American Spine Society).

Modern Grinding K-wires are made to order, Modern Grinding will contract manufacture a K-wire to your specialized need. Below is a table of typical K-Wires we manufacture. Please contact us for custom tips, custom sizes and partially threaded products.
