39773, AST-LOCK™ 77HS – High Strength, Heavy Duty, Bolt/Stud Locking – 250 mL

AST-LOCK™ 77HS – High Strength, Heavy Duty, Bolt/Stud Locking is best suited for fastener applications with diameters greater than 1″. This threadlocker has the best gap filling capabilities with excellent strength and non-migrating characteristics.

AST-LOCK anaerobics cure within metal connections, in the absence of oxygen, and at ambient temperatures. Available in a full range of strengths and viscosities. These anaerobics fill all surface imperfections and set to a tough, durable seal across the entire surface while distributing the stress load and reducing fastener fatigue. Vibration loosening is prevented and the connection is sealed and protected against corrosion.

AST-LOCK Anaerobic Threadlockers provide a solution for every practical industrial application. Lock screws in place and secure bolts and studs. Use right out of the bottle. Packaged in three popular sizes to fit your particular job or application.

AST-LOCK™ anaerobics are single-component, fast-curing, and solvent-free. Eliminates the need for other mechanical locking devices. Hardening only within the joint, anaerobics do not block or contaminate the system; excess resin outside remains in liquid state and is removed easily. Improve products quality and reliability.
