Description
Overview:
The Lockfast T43 (replaces Loctite 243) is a genuine, blue, anaerobic threadlocker supplied in a 50 ml bottle. Designed for locking and sealing threaded fasteners, it delivers dependable performance on construction and garden machinery exposed to vibration and heavy use. Its oil‐tolerant, thixotropic formulation works well on "as received" parts where full degreasing is impractical, helping prevent loosening and protecting threads from corrosion. With medium to medium‐high holding strength, T43 balances secure retention with serviceability on typical workshop bolts, screws and studs. Controlled viscosity supports clean, accurate application, and the adhesive is UV‐positive for inspection. Ideal for maintenance and repair on equipment such as compactors, generators, mowers and lawn tractors where reliable bolt and nut locking is required.
