A pre-applied threadlocker is not simply a coloured patch on a bolt. Its performance must be verified — and breakaway and prevailing torque are measured against specification before any batch is released.
The torque required to initiate movement of the fastener — the direct measure of the locking function.
The resistance generated while the fastener continues to rotate — verified against the applicable specification.
Verification of the treated thread area: band position, length and coverage.
Visual inspection for consistent, defect-free application on every production run.
Production and inspection records maintained against the applicable batch — traceable from dispatch back to process parameters.
Every batch. Controlled and verified.
Tell us your specification — breakaway, prevailing, or your OEM standard — and we will test against it.
