Loctite 290 High‑Strength Threadlocker Adhesive 50 ML

LOCTITE®
290™ is designed for the locking and sealing of
threaded fasteners. Because of its low viscosity and capillary
action, the product wicks between engaged threads and
eliminates the need to disassemble prior to application. The
product cures when confined in the absence of air between
close fitting metal surfaces and prevents loosening and
leakage from shock and vibration. The product can also fill
porosity in welds, castings and powdered metal parts.

LOCTITE®
290™ is tested to the lot requirements of Military
Specification Mil-S-46163A. Note: This is a regional approval.
Please contact your local Technical Service Center for more
