Threaded insert with cutting holes

Choosing the right threaded insert

‍

Different inserts suit different applications and requirements.

There are various reasons one might use a threaded insert in an assembly:

‍

• Repairs: replacing damaged or non-existent threads and strengthening the assembly's resistance at the same time.
• Fastening on soft materials: ensuring the part stays fastened in different materials such as composite materials, light alloys or compressed wood. Traditional internal threads (taps) are less reliable in this case
• Instant anchoring: creating resistant and durable threads in the material without any extra tools or pre-tapping during the install.

‍

In order to decide on a threaded insert, it is important to take such factors into account, while also considering the application environment and materials in question - as well as any possible mechanical stresses, accessibility, and obstruction. Once all that is done, you will need to decide between:

‍

• Standard self-tapping insert
• 3-hole threaded insert
• Made-to-measure threaded insert

‍

Why use a 3-hole threaded insert?

‍

The 3-hole threaded STHC insert is a conventional insert with three added holes, allowing any metal chips produced during the assembly process to be easily evacuated.

This thread insert with holes is a useful alternative to standard thread inserts, recommended for applications involving small heights and thicknesses.

‍

Our 3-hole insert offers the following advantages:

‍

• The insert's three openings allow metal chips to escape easily during the install process, making for clean and precise threading.
• With their compact design, these inserts are ideal for narrow and hard-to-reach environments.
• Reliable fastening in hard or medium-hard materials thanks to our in-house design, specially conceived to limit any loosening under stress.

‍

These inserts require a pre-drilled hole before fitting, but not any tapping, making them highly resistant.
