Product Description
The Heli-Coil Stanley Engineered Fastening 1191-3EN380 is a high-performance tanged wire thread insert engineered to form high-strength, free-running internal threads in low-strength parent materials. Formed from specialized Nitronic 60 stainless steel, this insert is highly specialized for gall resistance, making it the ideal solution for mating with stainless steel screws and operating reliably in highly sensitive, vacuum environments. Its precision coiled design enables the insert to dynamically adjust to material thermal expansions and contractions, permanently anchoring itself within the tapped hole to provide a wear-resistant, high-strength connection that safeguards against vibration and shock loosening.
Free-Running Tanged Design engineered to supply a completely smooth internal thread while maintaining a secure, permanent anchor via spring-like coil expansion once installed.
Nitronic 60 Construction provides excellent anti-galling and wear-resistant characteristics, ensuring optimal performance when paired with stainless steel fasteners.
Vacuum Compatibility is achieved through particle-free and non-magnetic material characteristics, removing the necessity for secondary plating or surface coatings.
Vibration Loosening Prevention eliminates the requirement for heavy locking mechanisms, lock washers, or chemical compounds by dynamically resisting shock and impact forces.
