LOCTITE 243 THREADLOCKER MEDIUM 50ML

Keep your assemblies secure and vibration-proof with Loctite® 243, the industry standard medium-strength threadlocker designed to prevent fasteners from loosening due to shock, vibration, and thermal expansion. Suitable for use on all metal fasteners, including stainless steel, aluminium, and plated surfaces, Loctite 243 provides long-lasting reliability in demanding mechanical and industrial environments.

Engineered with oil-tolerant technology, it performs even when parts are lightly contaminated with lubricants, cutting fluids, or corrosion prevention coatings. Once cured, Loctite 243 creates a strong, vibration-resistant seal that can still be disassembled with standard hand tools, allowing for easy maintenance and servicing.

Ideal for use on pumps, gearboxes, presses, and heavy machinery, Loctite 243 ensures a tight, leak-free hold that keeps your equipment performing at its best.
