Pre-applied nylon patch 267-28 KLF

ISO 7380-2 KLF — flange and nylon perform different functions

The flange is part of the head and creates a bearing surface on the fixed component. The nylon treatment is on the thread and increases mechanical rotational resistance. Selection requires separate checks of head geometry and engagement conditions for the treated thread.

Bearing surface under the flange

Compare flange diameter with the hole, available space and part shape. The bearing contact must suit the connection design. A flange alone does not mean leak tightness or justify removing an additional washer specified in the design.

Parameters to check

• Thread diameter, pitch and length, and screw length.
• Flange diameter, head height and hex key access.
• Material, mechanical property class and protective coating.
• KLF layer position relative to the nut or body thread.
• Operating conditions and reinstallation rules specified for the treatment.

Installing the nylon variant

Include the resistance caused by the nylon layer in the tightening procedure. It alone does not confirm achievement of the required clamping force. Select installation parameters for the specific screw design and connection construction, taking the low-head geometry into account.

Questions about ISO 7380-2 KLF

Is the variant without a flange interchangeable?

This requires comparing drawings, bearing surfaces and design requirements. See ISO 7380 with KLF.

Does nylon allow an unlimited number of installations?

Do not assume this. The documentation of the specific system confirms permitted cycles and operating temperature.

What should an enquiry to NERON in Piła include?

State ISO 7380-2, thread size, length, material, class, requirements for 267-28 KLF and number of pieces. Include a drawing if flange dimensions or locking treatment position matter. See the parent ISO 7380-2 category.
