Inserts Types & Capabilities

Providing thread reinforcement solutions across structural brackets, drone arms, and engine housings.

Wire Thread Inserts (Helicoils)

Helically coiled wire inserts in corrosion-resistant stainless steel. Providing lightweight internal threads that outperform parent materials under tension.

Key-Locking Inserts (Keenserts)

Solid one-piece inserts featuring keys that drive into parent materials. Guaranteeing zero rotational movement under intense thermal cycles and vibration.

Self-Tapping Inserts

Thick-walled solid inserts with cutting slots. Cuts their own threads into soft parent materials, ideal for high-stress carbon-composite aerospace plates.

Specifications & Capabilities

Positive means for protecting and strengthening all tapped threads across rigorous industrial requirements.

Manufacturing & Materials

  • Manufactured from Stainless Steel Grade AISI-304, 316, AMS-7245 & Space-age materials.
  • Available in Free Running and Screw Locking types.
  • Custom identification and surface coatings based on customer requirements.
  • Inserts and accessories are fully interchangeable with other leading brands.
  • Manufactured in a state-of-the-art facility following stringent quality norms.

Available Lengths

Wire Thread Inserts are available in five different lengths which are multiples of the diameter of the particular insert (X the diameter): 1D, 1.5D, 2D, 2.5D, and 3D

Free Running Inserts

Free running inserts have a spring-like appearance. When installed using any one of a variety of manual or automatic tools, they provide strong, permanent internal threads which resist heat and corrosion.

Screw Locking Helical Inserts

Designed to provide a screw-locking feature which retains screws or bolts under the most severe vibration or varying temperature conditions. In addition to the benefits afforded by free running inserts, GRIPCOIL screw locking inserts offer the additional security of prevailing locking torque.

As the bolt is wound through the locking chords of the insert, it deflects the wire. This deflection causes the insert to push against the bolt, resulting in a repeatable locking function from the insert.
