Keenserts (Key-locking Inserts)

Key Advantages:

• Mechanical locking with pins to prevent rotation and pull-out even under torque and vibration.
• Reinforces threads in soft materials and extends thread life with repeated use.
• An excellent solution for restoring stripped/damaged holes.
• Precision and uniformity per common standards for demanding industries.

Technical Specifications:

• Types: Standard / Heavy Duty / Miniature / Extra Heavy Duty.
• Internal sizes (metric): M4–M20 (additional options on request).
• Materials: coated (zinc/nickel) hardened alloy steel or AISI 303/304 stainless steel.
• Standards: NAS / MS / MIL, as well as DIN/ISO variations (depending on model).
• Operating and environmental temperature: dedicated versions for corrosion resistance/high temperature.

Common Applications:

• Aerospace/defense industry, automotive, automation and EOAT, molds and tooling.
• Engines, chassis, vibrating subassemblies and joints that are frequently opened/closed.

Quick installation (overview):

• Drill and tap to the manufacturer's dimensions (Oversize Tap).
• Insert and thread the Keensert in until fully seated in the surface.
• Drive the locking pins into the wall to prevent rotation/pull-out.
• Thread the dedicated screw into the desired internal diameter.
