A food-processing customer recently reported that the clamping screw on their sealing machine could no longer tighten. After checking their video, the cause was clear:
the M8 × 1.25 aluminum thread hole was completely stripped, and the screw simply free-spun.
Replacing the entire part would require downtime and several days of waiting for new components.
Because we keep M8 × 1.25 Keenserts (key locking inserts) in stock, we arranged immediate shipment so the customer could repair the machine without delay.
Quick Repair Using a Keensert
Once received, the customer restored the thread in less than 20 minutes:
1. Re-tap the damaged hole with M12 × 1.25 (drill Ø10.8 mm)
2. Install the Keensert flush with the surface
3.Drive down the locking keys to secure it
The thread regained full tightening strength instantly—no part replacement, no extended downtime.
