Keenserts – Keenserts (Key-locking Inserts)

Key Advantages:

• Mechanical locking with pins to prevent rotation and pull-out, even under torque and vibration.
• Strengthens threads in soft materials and extends thread life with repeated use.
• Excellent solution for repairing stripped/damaged holes.
• Precision and uniformity according to common standards for demanding industries.

Technical Specifications:

• Types: Standard / Heavy Duty / Miniature / Extra Heavy Duty.
• Internal Sizes (Metric): M4–M20 (additional options upon request).
• Materials: Hardened alloy steel coated (zinc/nickel) or stainless steel AISI 303/304.
• Standards: NAS / MS / MIL and variations according to DIN/ISO (depending on model).
• Operating and Environmental Temperature: Specific versions for corrosion/high temperature resistance.

Common Applications:

• Aerospace/defense industry, automotive, automation and EOAT, molds and tools.
• Engines, chassis, vibrating sub-assemblies, and connections that are frequently opened/closed.

Brief Installation (Overview):

• Drill and tap according to manufacturer's specifications (Oversize Tap).
• Insert and screw the Keensert until fully seated on the surface.
• Drive the locking pins into the wall to prevent rotation/pull-out.
• Screw in the designated bolt with the desired internal diameter.
