Description

V-COIL Self-Locking Thread Insert Type SL M 3 x 0.5 - 1.0 D

V-COIL Self-Locking Thread Insert Type SL M 3 x 0.5 - 1.0 D (100 pieces)

This red V-COIL self-locking thread insert Type SL is the specialized solution for high-stress connections exposed to vibration or shock. Through a special clamping effect, it reliably secures screws and bolts against loosening. It is made from high-quality, stainless steel and is used for the repair, reinforcement, and restoration of threads in materials with low shear strength.

Application & Advantages

Application Area:
- Thread repair of damaged or worn threads.
- Thread reinforcement of materials with low shear strength.
- Salvaging rejects, especially with faulty threads.
- Preferred for applications with vibration or shock effects.
Advantages:
- Made from high-quality austenitic stainless chrome-nickel precision profile steel wire.
- Offers increased temperature and corrosion resistance.
- Leads to higher thread load capacity after repair due to improved thread properties.
- Provides an additional security through clamping torque.
- Due to its compact design, it can be installed in existing constructions without any other preparations.
- The position is maintained by the radial pressure effect between the coils and the flanks of the tapped hole.

Functionality

One or more polygonal clamping coils of the insert exert a radial pressure on the external thread of the screw. Each clamping coil consists of a number of tangential strands that protrude beyond the diameter of the ordinary free-running coils.

When the bolt/screw is inserted, the clamping surfaces are displaced, creating the radial pressure that securely locks the screw. When the bolt/screw is removed, the clamping coils relax and return to their original shape. This allows for repeated screwing while maintaining a measurable degree of radial pressure.

Frequently Asked Questions (FAQ)

Q1: What is the main difference between this and a free-running thread insert? The main difference lies in the clamping effect. The self-locking Type SL exerts a radial pressure on the screw through special clamping coils, which secures it against loosening. A free-running insert does not have this function.
Q2: Why is the thread insert red? The red color serves as a clear identification feature for the self-locking Type SL thread insert. This allows you to easily distinguish it from other V-COIL inserts.
Q3: Can I use the insert in any material? Yes, the insert is designed for materials with low shear strength, such as aluminum or magnesium. It reinforces the thread and prevents damage.
Q4: What does the specification "M 3 x 0.5" mean? "M 3" stands for the metric nominal diameter of 3 mm, and "0.5" is the thread pitch. It describes the exact specification of the thread being repaired or reinforced.
Q5: What is the advantage of the "clamping effect" with vibrations? The clamping effect prevents the screw from self-loosening under dynamic loads like vibrations or shocks. The radial pressure generated holds the screw firmly in the thread.
Q6: Do I need special tools for installation? Yes, for a professional installation, you need specific V-COIL tools, including a matching tap and an installation tool, to ensure the correct function of the thread insert.

Secure your connections permanently and reliably – with V-COIL self-locking thread inserts.
