TufLok® and Nytemp® Patch for Thread-Locking Fastening Connections

A TufLok® or Nytemp® coating patch is a reliable and cost-effective way to secure fastening connections.

TufLok® and Nytemp®  patch coatings are a great option for thread-locking fastening joints. Parts of the thread are coated in highly-elastic, abrasion-resistant polyamide, which eliminates any axial play between the screw and the internal thread. Thus, it creates a dense, vibration-resistant fastening connection.

TufLok® and Nytemp® Patch Advantages

Superior Performance

The coating patch provides a high locking effectiveness.

No Curing Time

Screws with the coating patch can be used immediately.

High Material Resistance

The coating is resistant to alcohol, oil, gasoline and most thinners. It has an unlimited shelf life.

Tested Quality

The coatings are tested according to DIN 267 (part 28) and DIN EN ISO 2320.

Versatile

The Nytemp® and Tuflok® coatings are suitable for adjusting screws and can be applied to almost all metals.

Reusable

Screws with a Tuflok® or Nytemp® patch can be reused several times.

How the Coating Patch Works

TufLok® Patch

The Tuflok® patch is a self-locking nylon element that bonds permanently to the thread of a fastener. When the patch is engaged, it creates a wedge between the fastener and the mating part, compressing the nylon and creating metal to metal contact opposite the patch. This results in a positive vibration resistance and protects against loosening.

Features:

Blue color patch
Temperature range -56 °C to +120 °C

Nytemp® Patch

The Nytemp® patch operates according to the same mechanism as the Tuflok® patch, but is suitable for higher temperatures. It is comprised of a high temperature polymer permanently bonded onto the fastener thread. Due to the higher coating temperature, application is only possible on bright or phosphated threaded parts and stainless steel.

Features:

Orange color patch
Temperature range -56 °C to +200 °C

General Information on Coating Patches

Typical patch dimensions:

Coating in the core area: 90°
Edge zone (spray transition): up to 180°
Patch length: 4 to 6 threads
Uncoated start of the thread: 2 to 3 threads

The internal thread must have a countersink (no sharp-edged thread inserts); otherwise, the patch could be peeled off when the screw is installed. Approximately two to three threads underneath the head should not be patched.
