High-Performance Factory Unjc/Unjf Key Locking Thread Inserts M2 M2.5
Material: Stainless Steel 304
Packaging: Plastic Bag + Carton Case
Keylocking Thread Inserts are robust components, meticulously threaded both internally and externally, with integral keys at the top for unmatched performance.
Upon installation, the insert's locking keys are driven into the parent material's tapped threads, creating a secure mechanical lock that effectively resists both vibration and torsion.
Threaded inserts are a staple in both repair and manufacturing industries for workholders. Here's why key inserts are your go-to solution:
Reinforce weaker thread materials, such as aluminum and magnesium, with ease.
Designed for reliability, they withstand demanding wear and high vibration environments.
Available in a vast range of metric and inch sizes to suit any application.
Types of Thread Inserts
Heavy Duty Key Inserts Feature a robust, heavy-duty thread wall, making them suitable for most applications.
Thinwall Key Inserts Smaller OD thread size compared to standard and heavy-duty keenserts. Perfect for tight spaces with acceptable pull-out strength.
Solid Key Inserts These inserts have a solid base, ideal for relocating drilled or tapped holes.
Small Series M2-*** threaded inserts with dual key lock for secure fastening.
