Threaded Screw Inserts.

What are Threaded Screw Inserts?

Self Tapping Threaded Inserts are internally threaded components designed to create strong, reusable threads in softer host materials such as aluminium, wood, certain plastics and 3D printed materials. These inserts are capable of cutting their own threads during installation, removing the need for pre-threading or tapping.

Commonly referred to as Threaded Screw Inserts, Screw Thread Inserts or even Threaded Bushings, these components are particularly effective for repair work or in applications requiring frequent assembly and disassembly, such as jigs, fixtures, maintenance access panels and even robotics and hobby creations like miniatures. Creating reliable, durable threads for Machine Screws and other suitable fasteners.

How To Install Threaded Screw Inserts.

Installing Self Tapping Threaded Inserts is a straightforward process that eliminates the need for pre-threading. Begin by drilling a pilot hole slightly deeper than the length of the insert. The insert is then driven into the hole using an installation tool or a flat-head driver, depending on the insert design. As it is driven in, the insert cuts its own threads into the host material, ensuring a secure and durable fit. Care should be taken to maintain alignment and avoid over-torquing during installation.

FAQs.

Q: How to install a screw thread insert?

A: Accu has a great guide on installing every type of threaded insert: Discover how to install Self Tapping Inserts.

Q: How deep should threaded inserts go?

A: The pilot hole should be slightly deeper than the length of the insert to ensure full seating without bottoming out. For example, a 15mm insert typically requires a hole depth of approximately 16–17mm to allow for debris and tolerance.
