UC Components’ laser head marking service is designed to integrate seamlessly with our proprietary RediVac® process, delivering an even greater level of control, traceability, and assurance for our customers. This precision marking capability enhances the cleanroom-ready quality of our fasteners by adding permanent, high-contrast identifiers – such as part numbers, kit IDs, or QR codes – directly onto screw heads. Whether achieved through laser engraving or annealed laser marking, these markings are applied under strict protocols that match the cleanliness, precision, and reliability standards customers have come to expect from RediVac®. The result is a glove-fit service that supports clean critical environments and helps streamline your supply chain with less risk and more confidence.
Saving Time and Money While Controlling High-Value Parts
Our laser head marking service offers tangible cost savings when it comes to controlling high-cost components – like fasteners made from Inconel or custom-finished stainless steel. With permanent identification built directly into the part, customers reduce the risk of lost, mislabeled, or misused hardware during assembly or inventory handling. This is especially critical in environments where parts are electropolished, kolsterised, vacuum-baked, plated or coated – processes that can make traditional labels unreadable or introduce contamination. Some of these processes leave a very similar finish as well, making it hard to decipher which parts have gone through what process. Our laser engraving method removes material to create deep, abrasion-resistant marks that remain legible through these secondary treatments, ensuring parts stay traceable and identifiable.
Enhancing Oversight of Sub-Assemblies and Preventing Off-Spec Hardware
Companies often rely on multiple sub-assemblers and third-party vendors in today’s distributed manufacturing environment. With fasteners marked using our laser head marking service, customers gain a powerful tool for quality assurance. Unique identifiers and QR codes can be used to track individual fasteners, identify lot numbers, or associate screws with specific assemblies – providing full traceability throughout the supply chain. This level of control not only helps prevent assembly errors but also deters the use of off-spec hardware. The ability to confirm fastener authenticity at a glance is an invaluable asset in industries where even the smallest component must meet strict specifications.
Two Methods, One Goal: Permanent, Cleanroom-Compatible Identification
Our service supports two types of laser marking – engraving and annealed marking – each tailored to different material and process requirements.
Laser engraving uses a focused, high-energy beam to physically remove material from the fastener head, creating deep, highly durable marks. These markings hold up to harsh conditions, remain readable after coatings or plating, and are ideal for metals like Inconel and austenitic 300 series Stainless Steels. The engraved identifiers resist wear, solvents, heat, and frequent handling – making them perfect for semiconductor and high-purity manufacturing.
On the other hand, annealed laser marking is a surface treatment that uses low-power, de-focused heat to oxidize the metal surface, creating a color change without material removal. This smooth, corrosion-resistant mark is especially well-suited for stainless steel parts that will not be coated or electropolished. Because no surface is abraded, annealing maintains the integrity and corrosion resistance of the fastener, which is critical in cleanroom environments where surface disruption can pose a contamination risk.
A Clean, Controlled Process that Matches RediVac® Standards
Just like the RediVac® process itself, laser marking at UC Components is tightly controlled and executed under clean handling procedures. Whether engraving or annealing, the process is performed prior to cleaning, packaging, and vacuum sealing, ensuring that parts enter the cleanroom with all necessary identification already in place – no additional labeling or handling required.
In the case of annealed laser marking, the process involves a series of steps that carefully alter the metal surface at the molecular level. A low-power fiber laser heats the metal just enough to rearrange its crystal lattice, creating a permanent color change. Because no material is displaced, the surface remains intact – free from burrs, residues, or contaminants.
Built for RediVac®, Built for You
UC Components’ laser head marking service offers more than identification—it delivers confidence, compliance, and control. Whether you are managing sensitive cleanroom components, safeguarding high-value alloys, or streamlining sub-assembly oversight, our marking solutions offer a potent edge. Aligned with the RediVac® process and performed under the same high standards, this service helps customers reduce risk, prevent costly errors, and maintain complete visibility across their fastener inventory.
