Permanent thread-locking adhesive

This anaerobic compound locks and seals metal fasteners up to 25 mm diameter against vibration-induced loosening. It suits automotive, industrial and machinery maintenance where permanent retention is required. The red formulation indicates high-strength, heat-removable performance for critical assemblies.

Break-away torque 250 lb·in

The cured bond resists a break-away torque of 250 lb·in and a prevailing torque of 275 lb·in, far exceeding the 110/43 lb·in of medium-strength alternatives. This single figure confirms the adhesive will hold large bolts under severe cyclic loading without additional mechanical locking devices.

Temperature stability to 149 °C

After a 10-minute fixture time and 24-hour full cure, the adhesive maintains its locking strength across a continuous operating range of –54 °C to 149 °C. Sustained exposure within this window does not degrade the bond, and disassembly remains possible only by applying 260 °C heat for several minutes.
