Stainless Steel Key Locking Screw Thread Inserts , Bolt Sleeve Enhance The Strength

Introduction

The principle that the bolt sleeve enhances the connection strength of the aluminum alloy internal thread: the standard internal thread has the angle error and the pitch error of the thread processing, resulting in the small contact surface between the bolt and the thread in the base, and even point contact occurs. The uneven force of the bolt or base thread reduces the strength and fatigue life of the threaded connection.

The diameter of the plug screw sleeve in the free state is slightly larger than the diameter of the screw hole to be inserted. When assembling, the plug screw sleeve is pre-compressed by torsion force by installing the wrench thread guide ring to reduce the diameter, and the screw is screwed in with the special tap for the plug screw sleeve in advance. In a good internal screw hole, after installation, the bolt sleeve produces a spring expansion effect, is firmly fixed in the threaded hole, and will not move with the movement of the screw.

The bolt sleeve can increase the connection strength: it can be used for soft and low-strength alloy materials such as aluminum and magnesium, wood, plastic, rubber and other easily deformable and low-strength materials to avoid slippage and wrong teeth.

Specification

Advantage

1: Installing the bolt threaded sheath can effectively enhance the tightening strength and safety performance of the threaded hole, extend the use time of the threaded hole, and improve the quality of the product.

2: Installing the pin thread sheath in the threaded holes, such as spark plugs, mechanical molds, etc., which need to be frequently disassembled at high temperature and corrosion, can enhance the wear resistance, heat resistance and corrosion resistance of the threaded holes.

3: The bolt thread sheath has a repair function. When the machine screw hole thread for various reasons when the slide wire mess teeth, using a dedicated pin sheath wire tapping thread tapping, threaded bolt mounted jacket, slide wire mess of the threaded holes can be quickly repaired.

4: The installation tools and installation methods of the bolt socket are simple, and the installation is simple and can save time and improve work efficiency.

5: Bolt sockets are installed on machinery molds, products that require very high threaded hole strength and fastening safety performance on products such as aerospace industry, products, automobile industry, and shipbuilding industry.

Application

1. Quickly and effectively repair damaged threads on a variety of materials.

2. Enhance the thread strength on light materials, such as large and medium-sized non-ferrous metal castings, die castings and ductile ferrous metal base materials, as screw holes that are often screwed in and out.

3. It is especially suitable for use in environments requiring high-strength internal threads, with strong seismic and pull-out resistance. High strength wire thread insert than normally used, the base body is firmly connected with the work does not come off the substrate in the impact or vibration environment.

4. Remedy the wrong hole and avoid reprocessing the wrong part.
