For producing a lasting, heavy-duty female thread. With free running, true to gauge thread. Made of A2 stainless steel

Perfect combination of space-spacing and wear-resistant thread strength

In low-strength metal materials

In plastics

Optimal force distribution

Flexibility of the thread inserts compensates for pitch and angle errors

Thread insert sits securely

Minimised thread friction torque and minimised torsional stress

Increased corrosion resistance

Space and weight minimisation

Smaller number of required connection points and/or reduced screwing dimensions

Costs minimised

By reinforcing the thread, which effectively minimises the repair costs

Proof of Performance

The tolerance position of the ISO thread corresponds to 6H following installation.

Instructions

A resistant thread in 4 steps:

Step 1:

Drill a core hole or drill out the damaged thread

Step 2:

Create a receiving thread

By cutting using screw tap

Without cutting using thread moulding for an even more resilient receiving thread

Step 3:

Set the thread insert

The helical insert can be mounted both mechanically and also by hand using the corresponding screw-in tool.

Step 4:

Break the pin

Separate the follower pin by tapping gently on the predetermined break point with a pin breaker, and then remove. Automatic pin breakers are also available for series production.

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:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

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

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
04076
