1335884 243 blue, threadlocker 50cc

Loctite 243 is a blue, medium-strength threadlocker supplied in a 50cc bottle, ideal for high-volume service environments. This fluid is the most common choice for securing Harley-Davidson fasteners ranging from 1/4" to 3/4" (6mm to 20mm). It effectively prevents bolts from backing out due to vibration while maintaining a 20Nm strength on M10 hardware. Rated for temperatures up to 150°C, it provides a durable seal that can still be broken with regular hand tools when service is required. Loctite’s formula is trusted globally for its consistency and ability to protect threaded assemblies from corrosion and loosening.
