Main features
- Fast Anaerobic Cure
- High-Strength Heavy-Duty Locking
- Reduced Liquid Migration
Product Description
LOCTITE 2760 is a red, one-component anaerobic threadlocker for high-strength retention of heavy-duty metal fasteners. The medium-thixotropic liquid cures without air between close-fitting metal surfaces and is formulated for fast cure, reducing the need for activator on many assemblies. Its controlled flow helps limit migration after application. LOCTITE 2760 is suited to threaded joints exposed to high shock and stress, including bolts used in transmissions, construction equipment, and railroad assemblies. Torque performance is specific to defined steel fastener sizes, pretightening conditions, temperatures, and cure times.
Key features
- Fast anaerobic cure: The formulation develops strength quickly on close-fitting metal threads.
- High-strength locking: Cured joints are intended for heavy-duty shock- and stress-loaded fasteners.
- Reduced liquid migration: Medium thixotropy helps keep the applied product at the thread area.
Applications / Suitable for
- Transmission fasteners
- Construction equipment bolts
- Railroad assemblies and other heavy-duty threaded joints
