Why Choose TIME-SERT® Over Helicoil?

TIME-SERT® provides a stronger, more reliable repair than wire-coil inserts.

  • Solid bushing: Not a coil—supports full torque from head bolts.
  • Expansion locking: Prevents the insert backing out under engine heat cycles.
  • Flanged top: Stops the insert from sinking or pulling through.
  • Critical-repair approved: Ideal for cylinder heads and high-load fasteners.
  • Used by OEM and professional rebuilders: Trusted worldwide.

What's Included

  • 10 × TIME-SERT® M10 x 1.5 × 24.5mm inserts

Important Notes

These inserts require the correct TIME-SERT® M10 x 1.5 installation tooling. Not compatible with Helicoil tools. Ensure the 6mm recessed depth is followed to match BMW factory head bolt torque height.
