Wurth Bottle Chemical screw retainer HIGH strength - 50gms


Tough removable screw retainer and sealing compound – single-handed dispensing system

Suited for screw connections exposed to high stresses

  • A 100% seal is achieved - no additional securing parts are necessary
  • Protects against corrosion due to friction and against rust

Can only be removed once heated up to 300°C!

Under normal conditions can only be loosened by means of heat

Excellent media and thermal stability

Universal products with wide range of applications

Prevents detachment, e.g. through vibration and shock loads

No unwanted locking problems such as with mechanical screw retainers, for example

High resistance

Resistant to a large number of bases, gases, solvents, oils and fuels (see resistance list)

Silicone, solvent and oil-free

DOS system:

  • Practical one-handed operation thanks to the clever turn lock

One hand always remains free.

  • Continuously adjustable dispensing system

Dispensing can be adjusted to suit the application, and to keep consumption and costs to a minimum.

  • No residue material in dispensing neck

Costs optimised thanks to emptying with virtually no remaining product


The following plastics can be affected in the event of prolonged exposure: ABS, celluloid, polystyrene, polycarbonate (Macrolon), PMMA (Plexiglas), polysulfone, SAN (lurane, Tyril), Vinidur, vulcanised fibre and painted surfaces.

NSF-tested in accordance with NSF/ANSI 61 for use in service water and drinking water

Application area

For securing, fastening and sealing of high-strength threaded connections such as screws, stud bolts, nuts, threaded plugs, threaded inserts, ball and roller bearings, which normally no longer need to be loosened. The high-strength screw retainer is for use in the automotive and commercial vehicle industry, in metalworking and tool manufacturing, shipbuilding, mechanical engineering and engine construction, and electrical and electronics construction.


This liquid plastic cures when in contact with metal in the absence of oxygen. The contact surfaces must be dry, dust-free and grease-free. Moisten the adhesive surfaces sufficiently and put them together immediately.
