Adhesive Coated Screws (Thread Locking Screws)

Is your product’s performance and safety compromised by fasteners loosening under vibration?

Traditional manual application of threadlockers is inefficient, costly, and notoriously inconsistent. Our Adhesive Coated Screws (also known as Thread Locking Screws or Nylon Patch Screws) utilize advanced, automated pre-application technology to permanently bond a special engineering resin onto the threads, providing a reliable, set-and-forget solution for fastener locking.

Why Traditional Locking Methods Fall Short in Modern Manufacturing

• Manual Application: Inefficient and Costly.
  Assembly line workers spend valuable time applying liquid threadlocker to each screw, slowing down production and creating a messy work environment, which directly impacts efficiency and profit margins.

• Inconsistent Quality: Unreliable Torque Values.
  It’s nearly impossible to apply the same amount of adhesive manually every time. This leads to inconsistent locking torque, resulting in fasteners that are either too tight or too loose, creating a significant quality risk.

• Lock Washers: Bulky and Expensive.
  In compact product designs like consumer electronics, there is often no space for traditional lock washers. Adding an extra component also means adding extra procurement and inventory costs.

• Safety Hazards: The Risk of Loosened Screws.
  In precision instruments or high-vibration equipment, a loosened screw can cause more than just a rattle; it can lead to short circuits, structural failure, and serious safety incidents.

How Our Adhesive Coated Screws Solve Your Toughest Challenges

• 1. Precision Automated Coating for Unmatched Consistency
  Our fully automated, precision coating equipment ensures the location, length, and volume of the adhesive are identical on every single screw. This results in highly stable and predictable on-torque and off-torque values, guaranteeing reliable locking performance.

• 2. Streamline Your Assembly Process and Reduce Overall Costs
  Our pre-coated screws are ready to use right out of the box, eliminating the need for any secondary processing. They are perfect for automated assembly lines, saving significant time and labor costs associated with manual application.

• 3. Durable Locking Performance with Reusability
  The nylon patch we primarily use offers excellent elasticity and resilience. It maintains effective locking torque even after multiple installations and removals, making it ideal for products that require maintenance or service.

• 4. Safe, Eco-Friendly, and Compliant with Industry Standards
  All adhesives we use are compliant with RoHS and other environmental standards. They are non-toxic and safe for use in demanding industries, including medical devices and consumer electronics.
