Tanged Screw Lock
Tanged Screw Locking Inserts contain one or more coils that have a series of straight segments. Upon entry of the bolt these straight segments are flexed outwardly, creating pressure on the bolt. This pressure is applied between the flanks of the bolt thread so that contact area is maximized. Locking inserts are manufactured to meet the locking torque requirements specified in NASM8846. NASM8846 requires the inserts to pass a 15 cycle torque test.
The resilient characteristics of each coil in a helical Insert allows it to adjust independently to secure the maximum surface contact with individual threads in the parent material. As a result, loads are distributed more evenly. Stress and fatigue concentrations are reduced to maximize thread strength and increase the reliability and life of the fastening system.
The stainless steel used to produce coil thread inserts resists corrosion under normal environmental conditions. Galvanic action within the thread assembly is reduced, further adding to the life of the fastening assembly. These Inserts are typically used with temperatures from -320F Degrees to +800F degrees (-195.6C to +426.7C).
Precision engineering, exacting manufacturing standards, and stringent quality control procedures assure a high quality product that meets or exceeds all applicable military and aerospace standards. Helical inserts are available in Bulk and on Strip Feed Reels.

6 Recommendations for Vibration Resistant Fasteners
Traditional fasteners loosen under vibration. No matter how hard you tighten them, nuts and bolts will loosen with time if they are subjected to regular shaking.
All About Helical Insert Applications
Stripped threads can be a nightmare, especially when dealing with soft materials such as aluminum, magnesium, or plastic. When you have a stripped fitting where a bolt just won’t hold or needs reinforcement, you need to find a way to make a fastener connection that is strong and worry-free.

Why Coil Thread Inserts Are Unique Among Fasteners
Threaded fasteners need a solid substrate for lasting performance. The threads must be solidly anchored in the material without loosening or pullout, which can be challenging with softer materials, such as wood and plastics.
