Self-tapping insert with collar / self-cutting threaded insert with head – industrial B2B fastening solution

Product description and technical specifications

The self-tapping insert with collar / slotted self-tapping threaded insert with head is a metal threaded insert that forms its own internal thread (from M4 to M10) in a pre-drilled hole, eliminating the need for prior tapping. This is achieved through a special non-metric external thread combined with a cutting slot, allowing the insert to cut a strong mating thread during installation. It is suitable for a wide range of base materials such as non-hardened steel, exotic hardwood, cast iron and thermoplastics, creating a high-strength, wear-resistant and load-bearing internal thread.

The integrated flange increases pull-out resistance and surface support in through-holes, making this insert ideal for demanding industrial and B2B assembly applications.

Description

Key technical features

• Self-tapping threaded insert with collar, enabling thread formation without pre-tapping and reducing production steps.
• Metric internal thread range: M4 to M10, compatible with standard ISO metric screws and bolts.
• Special external thread with cutting slot, ensuring strong mechanical anchoring in the parent material.
• Material options: hardened steel, white zinc plated for general industrial use, and stainless steel AISI 303 for improved corrosion resistance.
• Flanged head design, increasing load distribution and pull-out strength in through-holes.
• Recommended installation tools: manual insertion tool 610 or mechanical insertion tool 620 for precise, axial installation.
• Applicable base materials: non-hardened steel, cast iron, hardwood, thermoplastics and semi-hard substrates.

Technical advantages for industrial B2B assembly

• Fast installation without tapping, reducing cycle time and tooling costs.
• Durable, wear-resistant internal thread, suitable for repeated assembly and disassembly.
• Enhanced pull-out resistance thanks to the flange, improving reliability in high-load applications.
• Wide material compatibility, making the insert suitable for both metal, wood and plastic assemblies.
• Stainless steel option available for corrosive environments and precision engineering applications.

Typical industrial applications

• Machine and equipment manufacturing, where reliable and serviceable threaded connections are required.
• Metal assemblies without the need for thread cutting operations.
• Exotic hardwood constructions demanding strong internal threads.
• Thermoplastic components and technical panels, ensuring stable fastening in deformation-sensitive materials.
• Maintenance, repair and retrofit operations in industrial environments.

Installation guidelines and best practices

1. Pre-drilling: drill the hole to the recommended diameter based on the outer diameter of the insert to allow correct cutting action.

2. Controlled insertion: screw in the insert using the appropriate insertion tool (610 or 620) to maintain correct alignment.

3. Final inspection: ensure the insert is seated flush against the surface and that the internal thread is ready for bolt or screw installation.
