Description
Overview:
Loctite 243 Threadlock 50ml (part ref. 963 0243) is a medium-strength, blue, anaerobic acrylic adhesive for locking and sealing threaded fasteners. It cures in the absence of air when confined between metal surfaces, helping stop bolts, screws, studs, and nuts working loose under vibration or shock. The formulation works well on common metals, including stainless steel and zinc-plated fasteners, and is tolerant of light oil residue from maintenance. Supplied in a 50ml bottle, it is suitable for assembly and repair across construction equipment and garden machinery where reliability matters. Typical uses include engines, pumps, gearboxes, and frame fixings on vibrating tools and machines. Once cured, joints remain secure yet can usually be disassembled with standard hand tools for routine servicing.
Key Features:
- Medium-strength hold for secure retention yet serviceable with normal hand tools
- Resists vibration and shock to reduce loosening and downtime
- Works on stainless steel and plated fasteners commonly found in plant and garden kit
- Tolerant of slight surface oil, helping in real-world maintenance conditions
- Seals threads to help prevent leaks, rust, and fretting corrosion
- Thixotropic consistency limits run-off and migration during application
- Blue colour aids visual identification during assembly and inspection
- 50ml bottle supports multiple jobs; controlled tip helps place adhesive precisely
- Cures between metal threads; no mixing or special tools required
- Genuine Loctite part for consistent, proven performance
Typical Applications:
Securing threaded fasteners on vibrating machinery and tools such as compactors, generators, mowers, strimmers, hedge trimmers, chainsaws, tillers, and pressure washers. Common jobs include engine covers, pulley and sprocket bolts, blade carriers, pump housings, handlebar clamps, guards, brackets, and gearbox fixings. Useful in workshops and on-site repairs to keep assemblies tight and reduce rework.
