Central Wire manufactures bar stock for aerospace and beyond!

Turning premium bar stock metals into fasteners, engine components, fasteners and more is made easy with our quality manufacturing. 

This comprehensive bar stock blog will cover how bar stock is used in mission critical applications, its precise manufacturing process, centerless grinding and details on a range of premium alloys.  

Read below to see why this product is so versatile, from its unique manufacturing process to the qualities that make it last.  

Mission Critical Manufacturing

Maintenance of passenger aircraft in airport hangar.

Our state-of-the-art Perris, California facility holds ISO 9001:2015 and AS9100:2016 certifications, which focuses on aerospace market needs. This unwavering attention to quality allows us to produce bar stock products that are reliable and consistent enough for use in the most demanding aerospace and commercial applications. 

From rivets and bolts to screws and fasteners, bar stock is a versatile material that can be transformed into a wide range of hardware. But before it can become bar stock, it must first be processed as wire rod.  

Manufacturing Process

To learn in full detail how our products are made from beginning to end, visit the manufacturing capabilities page on our website. There you will read about all the different steps required to transform raw materials into the products our customers specify every day. 

This multi-step process entails a strategic plan of annealing, stress relieving, drawing, and coating to impart the correct hardness and tensile strength on the metal.  

Just like most of our products, bar stock begins its life as a raw material that requires many steps, such as cleaning and processing, before it reaches its final form. Once drawn to its appropriately designated diameter, it is straightened, cut to length, and packaged to customer specification. To help guarantee consistency, material is bundled by lot to ensure traceability back to the mill source. 


From alloy selection to packaging requirements, our goal is to provide you with a customizable product capable of meeting all your tensile strength, hardness, and diameter tolerance specifications.  

Our Perris facility has the capacity to produce bar stock up to 0.750 inches in a variety of stainless, nickel, and specialty alloys which all exhibit unique properties in machining, cold heading, and hot heading applications.  

Centerless Grinding

Centerless grinding process

A crucial component of the efficiency and consistency in our specialty bar stock manufacturing is our through-feed centerless grinding capabilities. This process lends the required precision that created exact dimensions and tolerances for your ideal product. 

The process consists of a workpiece being constantly fed through the machine between a grinding wheel and a regulating wheel, ensuring precision. The exact sizing capabilities allow for use in precise applications such as bushings, fasteners and landing gear components.  


With quality materials and manufacturing comes versatility and reliability. Our bar stock products can be found in countless different industries, including, but not limited to: 

  • Aerospace 
  • Automotive 
  • Industrial 
  • Oil and Gas 
  • Renewable Energy
