Key-Locking Threaded Inserts Keyserts
Key-locking threaded inserts, also called keyserts, are precision-engineered internally threaded bushings that reinforce tapped holes in soft or vibration-prone materials. Sunbo Technology Co. Ltd supplies these in stainless steel 304 and carbon steel with zinc plating, designed to prevent rotation under torsion or vibration through a key-locking action. They are available in both metric and imperial thread series, with thinwall, heavy duty, extra heavy duty, and solid styles to match application demands.
The inserts are compatible with materials such as aluminum, magnesium, and cold rolled steel, offering enhanced corrosion resistance through passivation. Standard installation uses drills and taps, and they are easily removable for maintenance or rework. Typical industry grades for such inserts include A2-70 stainless steel or class 8.8 carbon steel, with thread tolerances of 6H for metric and 2B for imperial as standard.
Common applications include truck and RV assemblies, machinery, small engines, molds, tool and die, and MRO tasks. Buyers in OEM manufacturing and industrial maintenance source these inserts for their durability and reliable performance in high-stress environments. They are packaged individually or in kits for export-ready supply, with bulk trade terms available on request.

Sourcing Key-Locking Threaded Inserts Keyserts from Sunbo Technology Co. Ltd - China Import Guide
Before ordering, verify the thread series, size, and style to ensure compatibility with your application. Confirm the material grade and corrosion resistance requirements, as these directly impact performance in specific environments. Request samples or technical drawings to validate dimensions and tolerances.
Logistics details such as lead time, Incoterms (e.g., FOB, CIF), and payment terms should be clarified with Sunbo Technology Co. Ltd. Bulk shipments are typically palletized, and packaging options may include individual or kit-based formats. Confirm port of loading and any export documentation required for customs clearance.
Inspect the inserts for dimensional accuracy, thread integrity, and surface finish upon receipt. Check for passivation quality on stainless steel variants and zinc plating uniformity on carbon steel. Request a material test report (MTR) to verify compliance with specified grades and standards. Functional testing under vibration or torsion can confirm the key-locking mechanism’s effectiveness.
