LOCTITE® GRD AV™ (LOCTITE® 087™) is a high strength, one-component, anaerobic threadlocker used to lock and seal large coarse threaded nuts, bolts and studs where high locking strength is required. It is a red, medium viscosity dimethacrylate ester liquid that fluoresces under UV light. It is tested to the lot requirements of Mil-S-22473E (regional approval); each lot produced in North America is tested to the requirements of ASTM D5363.
Typical Properties
- Specific gravity (25 °C) 1.07; viscosity 100–250 mPa·s
- Prevail torque after 6 hours (3/8 x 24 steel nuts and bolts) 5.7–28.3 N·m
- After 24 hours breakaway torque 7 N·m; prevail torque 11.3–28.3 N·m
- Dielectric breakdown strength 9.8 kV/mm
Resistance (300 hours at 93 °C, % of initial strength)
- Motor oil and phosphate ester 100%; water and ethylene glycol 110%
Use and Storage
- If hand tools do not work, heat the fastener to about 250 °C and disassemble while hot
- Store at 8–21 °C in a dry location in unopened containers
