Key locking threaded insert : The Best Vibration Protection for High-Tech Industries

Top Screw Metal Industrial Company, established for many years, continuously innovates and develops products that meet the needs of the industry. Recently, they have launched "anti-loosening bushings, keyed thread inserts, and dowel pin anti-loosening bushings." These are suitable for vibration protection in aluminum alloy engines of electric and gasoline vehicles, especially in machinery, aerospace, and high-precision equipment for rocket launches, enhancing the vibration protection of the main products.

The anti-loosening bushing is installed by drilling a standard pilot hole, chamfering it with a (82-100 degree) countersink drill, and then tapping the hole. Insert the bushing into the hole to a depth of about 0.25-0.70mm, then insert the dowel pin into the assembly tool’s positioning pinhole, and continue to turn it to the bottom. After removing the positioning pinhole, rotate the installation tool 45 degrees and place it over the dowel pin. Use a hammer to tap it until the four dowel pins are flush with the surface, completing the assembly.

Features and Advantages of Anti-Loosening Bushings

• Physical Fixation: The bushing with fixed pins prevents rotation through physical means.
• High Strength and Stability: Provides strong pull-out strength and stability.
• Ease of Installation: Requires only standard drills and taps, no special skills needed.
• Versatile Application: Can be used on various substrates without the risk of cross-threading.
• Removability: No gaps to facilitate easy destruction and removal.
• Compatibility: Suitable for American, European, and spark plug sizes.
• Variety of Styles: Available in thin-wall and heavy-wall versions, made of iron and stainless steel.

The company holds 20 patents and 50 patent certificates and has passed ISO9001:2015 international quality assurance certification. Their products are marketed in over 80 countries worldwide.
