The insert is made of high tensile stainless steel and provides a permanent internal screw thread

The Helicoil M3 Screw Lock is a high-quality, precision-formed screw thread coil that provides a permanent internal screw thread. The insert is made of high tensile stainless steel, ensuring superior strength and durability.

The manufacturing process involves forming the stainless steel into a diamond shape, resulting in a mirror-like surface finish. This precision-formed wire is then carefully wound into a spiral coil. When installed into Heli-Coil tapped holes, this coil provides a permanent 60-degree internal screw thread. This innovative design allows the insert to accommodate any standard bolt or screw, making it a versatile solution for a wide range of applications.

The installation process is where the high tensile stainless steel insert truly comes to life. During installation, the inserting tool applies torque to the tang, reducing the diameter of the leading coil and allowing it to enter the tapped thread. Once installed, each coil of the insert expands outward with a spring-like action, permanently anchoring itself in place. This expansion ensures a tight and secure fit, providing the foundation for strong and reliable screw joints.

The Helicoil M3 Screw Lock insert offers significant advantages over traditional methods. Firstly, it provides increased thread strength due to the high tensile nature of the stainless steel. Secondly, it eliminates thread wear, as the insert is designed to withstand frequent use without showing signs of wear and tear. Additionally, the insert offers corrosion resistance, ensuring long-lasting performance even in harsh environments.

The Helicoil M3 Screw Lock is an excellent choice for applications requiring a strong, permanent, and reliable internal screw thread. The high tensile stainless steel construction ensures superior performance and longevity, making it a trusted solution for professionals across various industries.

The Helicoil M3 Screw Lock has a clamping area for captive screw locking

The Helicoil M3 Screw Lock is a thread insert with a captive screw lock. It has a clamping area that serves as a captive screw lock, achieved through one or more polygonal turns that have a clamping effect on the flanks of the installed screw. This clamping effect provides a self-locking torque that prevents the screw from loosening under vibration or impact.

The Helicoil M3 Screw Lock is part of the Böllhoff HELICOIL® Plus Screwlock range. It is available in both UNC and UNF thread technology, and in stainless steel A2. The Helicoil M3 Screw Lock is coloured red, which makes it easily distinguishable before and after installation.

The Helicoil M3 Screw Lock has a number of advantages. It provides high thread strength, wear resistance, corrosion resistance, and temperature resistance. It also offers a tight fit, increases quality and value, and saves on costs. The insert is easy to install and can be used with screws of higher property classes (8.8 and higher).

The Helicoil M3 Screw Lock is ideal for applications where low shear strength materials are used, such as aluminium or aluminium-magnesium alloys. It can also be used for original equipment applications, repair, and overhaul.

The insert is suitable for use with screws of higher property classes (8.8 and above)

The HELICOIL® Plus Screwlock thread insert is a significant upgrade from the classic coil thread insert. It features a screw-locking area that locks a screw in place using resilient frictional locking. This locking mechanism ensures that the prevailing torques comply with international standards.

The HELICOIL® Plus Screwlock thread insert's compatibility with higher property class screws is due to its unique design and high-quality materials. The insert is precision-formed into a diamond shape, resulting in a mirror-like surface finish. This attention to detail ensures that the insert can handle the increased strength and torque of higher property class screws without failing or stripping.

Additionally, the insert's material, high-tensile stainless steel, provides the necessary strength and durability to accommodate higher property class screws. The insert's coils expand outward with a spring-like action during installation, permanently anchoring the screw in place. This expansion, coupled with the insert's high-quality materials, ensures that it can securely hold higher property class screws without compromising its integrity.

The compatibility of the HELICOIL® Plus Screwlock thread insert with higher property class screws makes it a versatile and dependable solution for a wide range of applications, from original equipment installations to repair and overhaul projects.

The Helicoil M3 Screw Lock is used in the aviation industry

The Helicoil M3 Screw Lock is a type of helical insert, also known as a screw thread insert (STI). It is used in the aviation industry to create strong, load-bearing joints. Helicoil M3 Screw Locks are made of coiled wire and are inserted into Heli-Coil tapped holes, providing permanent internal screw threads.

The Helicoil M3 Screw Lock is a "Screw-Locking" insert that provides self-locking torque on the male member by a series of "chords" on one or more of the insert coils.
