Keensert Stainless Steel 304 Key Locking Thread Insert Thread Repairing
KEENSERT stainless steel 304 key locking thread insert thread repairing
Premium Material: Stainless Steel 304
Secure Packaging: Plastic Bag + Carton Case
Innovative Design: Keylocking Thread Inserts are robust and feature internal and external threading with keys attached at the top.
Reliable Installation: Once the insert is screwed into the parent material, the locking keys are driven down into the tapped threads, creating a strong mechanical lock to prevent rotation due to vibration or torsion.
Threaded inserts are essential in the repair and construction of workholders. Here's why key inserts are the go-to solution for manufacturers:
Versatility: Ideal for reinforcing weaker thread materials like aluminum and magnesium.
Durability: Reliable under demanding wear and high vibration conditions.
Adaptability: Available in a wide range of metric and inch sizes to suit your specific application.
Types of Thread Inserts

Thinwall Key Inserts Designed with a smaller OD thread size for use in tight spaces with acceptable pull-out strength.
Solid Key Inserts These inserts have a solid base, perfect for relocating drilled or tapped holes.
Small Series M2-M12 threaded inserts with 2 key locks.
