TimeSert

Time-Sert is a brand of threaded inserts used to repair damaged or stripped internal threads in metal components. The Time-Sert system employs solid, heat-treated inserts with a knurled outer surface and an internal female thread. They are installed with a dedicated installation tool, driving the insert into a prepared hole until it sits flush or slightly below the surface. Unlike coil-based inserts, Time-Sert inserts are a single, self-contained piece that provides full-length thread engagement.

Design and materials: Time-Sert inserts are manufactured in brass for light alloys or stainless steel for corrosion resistance, and are produced in a range of imperial and metric sizes. The outer diameter and length are chosen to fit specific hole sizes, and the internal thread matches the original fastener size. Time-Sert kits typically include drill bits, taps, installation tools, and a selection of inserts.

Application and use: The repair process begins by enlarging the damaged hole to a standard drill size, followed by tapping to the next larger standard thread. After cleaning the hole, the insert is installed with the tool until it is flush with the surface. The original fastener size can then be threaded into the insert. Time-Sert is widely used in automotive, aerospace, and industrial applications to restore thread integrity in aluminum, steel, magnesium, and other materials. It is often favored for providing strong, durable threads in thickness-limited or repaired holes, and for situations requiring reusable threads.

Overview: Time-Sert is regarded as a durable alternative to helicoils and other coil-type inserts, offering solid, full-length threads and corrosion-resistant materials suited to demanding environments.
