1185-02EN129 by HELI-COIL

The Heli-Coil 1185-02EN129 by Stanley Engineered Fastening is a high-performance tanged free-running insert micro-engineered to form high-strength internal threads in delicate, low-density parent materials like aluminum and magnesium alloys. Precision cold-rolled from specialized Nitronic 60 stainless steel wire with a distinctive diamond-shaped cross-section, this wire thread insert automatically expands elastically outward upon installation to establish a permanent, spring-like retention force without requiring keying or staking. Its advanced material composition delivers exceptional anti-galling protection, completely eliminating the need for additional anti-seize lubricants when using stainless steel screws. This mini wire insert yields a permanently wear-resistant thread that optimizes joint load distribution, shielding critical electronic, medical device, and vacuum-environment assemblies against stripping and structural erosion.

Free-Running Profile Provides a smooth, conventional internal thread track that allows standard miniature mating bolts to rotate unhindered without added torque resistance.

Nitronic 60 Composition Offers superior inherent anti-galling performance and wear resistance, making it perfect for vacuum applications and eliminating the need for extra coatings or lubrication.

Tanged Configuration Features a traditional driven installation tang that provides positive mechanical engagement with standard mandrels for highly accurate depth seating.
