Removable screw retainer and sealing compound – one-handed dispensing system

Produces medium-strength connection

Can be removed using normal tools

Can also be applied to stainless steel and passivated surfaces

No "accelerator" or "activator" required

Excellent media and thermal stability

Universal products with a wide range of application

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

No unwanted attachment problems such as with mechanical screw fixings

High resistance

Resistant to a large number of bases, gases, solvents, oils and fuels


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. We always recommend that you conduct your own tests.

NSF-tested in accordance with ANSI 61, DVGW (German association of gas and water) (DIN EN 751-1)

The usage instructions are recommendations based on the tests we have conducted and our experience; carry out your own tests before each application. Due to the large number of applications and storage and processing conditions, we do not assume any liability for a specific application result. Insofar as our free customer service provides technical information or acts as an advisory service, no responsibility is assumed by this service except where the advice or information given falls within the scope of our specified, contractually agreed service or the advisor was acting deliberately. We guarantee consistent quality of our products. We reserve the right to make technical changes and further develop products.

Application area

Automotive and commercial vehicle industry, metal and tool manufacturing, shipbuilding, machine and engine construction, electrical and electronics construction


The surface must be free of oil, grease and other contaminants. The best adhesive results are achieved by first cleaning with metal cleaner 7063. Observe the flash-off times!

For blind holes, apply several drops inside along the thread up to the base of the hole. For through holes, apply several drops to the point on the screw where the nut will sit. In sealing applications, apply the product around the outer thread. The mid-strength screw retainer cures anaerobically, meaning that it only hardens where the adhesive has no contact with atmospheric oxygen. At the same time, the hardening speed continues to be influenced by the catalytic effect of metal and the gap width. Excessive adhesive that is pressed out of the gap between the two parts will not harden and can be removed with a dry cloth or a cloth saturated with acetone cleaner.

Passive materials: nickel, zinc, tin, precious metals, aluminium with minimal copper and/or manganese content, high-alloy steel, oxide or chromate coats, plastic, glass and ceramic.

Packaging unit

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.

Structure of our article number

The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:

Important information:

The information given is based on experience and laboratory conditions and is designed as a guide. However, the actual suitability of a glove depends on the individual conditions of its use and must be confirmed by an appropriate test under operational conditions. Given the variety of materials and chemicals used, the possibility of incompatibility or usage problems for the wearer cannot be excluded in individual cases. We would be happy to advise you about optimum solutions.
