    Quickly and easily repair stripped or damaged threads, or create stronger original threads in die castings or plastics with our Helical Screw Thread Inserts. Coil tension securely holds the insert in place without undue tension on the surrounding material. The inserts are vibration and impact resistant. Made from corrosion resistant stainless steel, they offer a wide temperature tolerance.

  • - HSS STI Plug Tap

    HSS STI Plug Tap for M2 x 0.4 Thread Repair Kit

    Screw Thread Insert (STI) Taps are used specifically to create threads for Helical Thread Inserts. STI Taps are oversized so the thread produced will accept a Helical Wire Insert of the same nominal size and pitch - meaning the hole created by the Tap goes back to the original dimension allowing the original fastener to be used.

    The "Plug" style Tap is ideal for starting or tapping a through hole. The Tap can be used and the Helical Insert can be installed in most materials including aluminum, magnesium, cast iron, carbon steel, stainless steel, and plastic.

Simple Installation Process


The first step in creating a new, stronger thread is cleaning up the original, damaged threads. This is done with a standard drill, kits do not include drills, please find the recommended drill size below. The hole is then tapped with an oversize (STI)* tap provided in each thread repair kit. The free diameter of the helical threaded inserts is larger than the new threaded hole, but it is easily “wound” into place with the inserting tool provided.

Once in place, the helical threaded insert tends to spring back to its original diameter, giving it a very strong grip in the hole. Finally, the driving tang is broken off by tapping downward with the end of the inserting tool.

    Quickly and easily repair stripped or damaged threads, or create stronger original threads in die castings or plastics with our Helical Screw Thread Inserts. Coil tension securely holds the insert in place without undue tension on the surrounding material. The inserts are vibration and impact resistant. Made from corrosion resistant stainless steel, they offer a wide temperature tolerance.

  • - HSS STI Plug Tap

    HSS STI Plug Tap for M8 x 1.25 Thread Repair Kit

    Screw Thread Insert (STI) Taps are used specifically to create threads for Helical Thread Inserts. STI Taps are oversized so the thread produced will accept a Helical Wire Insert of the same nominal size and pitch - meaning the hole created by the Tap goes back to the original dimension allowing the original fastener to be used.

    The "Plug" style Tap is ideal for starting or tapping a through hole. The Tap can be used and the Helical Insert can be installed in most materials including aluminum, magnesium, cast iron, carbon steel, stainless steel, and plastic.

Simple Installation Process


The first step in creating a new, stronger thread is cleaning up the original, damaged threads. This is done with a standard drill, kits do not include drills, please find the recommended drill size below. The hole is then tapped with an oversize (STI)* tap provided in each thread repair kit. The free diameter of the helical threaded inserts is larger than the new threaded hole, but it is easily “wound” into place with the inserting tool provided.

Once in place, the helical threaded insert tends to spring back to its original diameter, giving it a very strong grip in the hole. Finally, the driving tang is broken off by tapping downward with the end of the inserting tool.

Once in place, the helical threaded insert tends to spring back to its original diameter, giving it a very strong grip in the hole. Finally, the driving tang is broken off by tapping downward with the end of the inserting tool.

  • - HSS STI Plug Tap

    HSS STI Plug Tap for M12 x 1.25 Thread Repair Kit

    Screw Thread Insert (STI) Taps are used specifically to create threads for Helical Thread Inserts. STI Taps are oversized so the thread produced will accept a Helical Wire Insert of the same nominal size and pitch - meaning the hole created by the Tap goes back to the original dimension allowing the original fastener to be used.

    The "Plug" style Tap is ideal for starting or tapping a through hole. The Tap can be used and the Helical Insert can be installed in most materials including aluminum, magnesium, cast iron, carbon steel, stainless steel, and plastic.

Simple Installation Process


The first step in creating a new, stronger thread is cleaning up the original, damaged threads. This is done with a standard drill, kits do not include drills, please find the recommended drill size below. The hole is then tapped with an oversize (STI)* tap provided in each thread repair kit.

  • - HSS STI Plug Tap

    HSS STI Plug Tap for M15 x 1.5 Thread Repair Kit

    Screw Thread Insert (STI) Taps are used specifically to create threads for Helical Thread Inserts. STI Taps are oversized so the thread produced will accept a Helical Wire Insert of the same nominal size and pitch - meaning the hole created by the Tap goes back to the original dimension allowing the original fastener to be used.

    The "Plug" style Tap is ideal for starting or tapping a through hole. The Tap can be used and the Helical Insert can be installed in most materials including aluminum, magnesium, cast iron, carbon steel, stainless steel, and plastic.

Simple Installation Process


The first step in creating a new, stronger thread is cleaning up the original, damaged threads. This is done with a standard drill, kits do not include drills, please find the recommended drill size below. The hole is then tapped with an oversize (STI)* tap provided in each thread repair kit. The free diameter of the helical threaded inserts is larger than the new threaded hole, but it is easily “wound” into place with the inserting tool provided.

Once in place, the helical threaded insert tends to spring back to its original diameter, giving it a very strong grip in the hole. Finally, the driving tang is broken off by tapping downward with the end of the inserting tool.

  • - HSS STI Plug Tap

    HSS STI Plug Tap for M22 x 2 Thread Repair Kit

    Screw Thread Insert (STI) Taps are used specifically to create threads for Helical Thread Inserts. STI Taps are oversized so the thread produced will accept a Helical Wire Insert of the same nominal size and pitch - meaning the hole created by the Tap goes back to the original dimension allowing the original fastener to be used.

    The "Plug" style Tap is ideal for starting or tapping a through hole. The Tap can be used and the Helical Insert can be installed in most materials including aluminum, magnesium, cast iron, carbon steel, stainless steel, and plastic.

Simple Installation Process


The first step in creating a new, stronger thread is cleaning up the original, damaged threads. This is done with a standard drill, kits do not include drills, please find the recommended drill size below. The hole is then tapped with an oversize (STI)* tap provided in each thread repair kit. The free diameter of the helical threaded inserts is larger than the new threaded hole, but it is easily “wound” into place with the inserting tool provided.

Once in place, the helical threaded insert tends to spring back to its original diameter, giving it a very strong grip in the hole. Finally, the driving tang is broken off by tapping downward with the end of the inserting tool.

  • - HSS STI Plug Tap

    HSS STI Plug Tap for M42 x 4.5 Thread Repair Kit

    Screw Thread Insert (STI) Taps are used specifically to create threads for Helical Thread Inserts. STI Taps are oversized so the thread produced will accept a Helical Wire Insert of the same nominal size and pitch - meaning the hole created by the Tap goes back to the original dimension allowing the original fastener to be used.

    The "Plug" style Tap is ideal for starting or tapping a through hole. The Tap can be used and the Helical Insert can be installed in most materials including aluminum, magnesium, cast iron, carbon steel, stainless steel, and plastic.

Simple Installation Process


The first step in creating a new, stronger thread is cleaning up the original, damaged threads. This is done with a standard drill, kits do not include drills, please find the recommended drill size below. The hole is then tapped with an oversize (STI)* tap provided in each thread repair kit. The free diameter of the helical threaded inserts is larger than the new threaded hole, but it is easily “wound” into place with the inserting tool provided.

Once in place, the helical threaded insert tends to spring back to its original diameter, giving it a very strong grip in the hole. Finally, the driving tang is broken off by tapping downward with the end of the inserting tool.
