Heavy Key - Locking Thread Insert Heavy Duty With All Sizes Machine Fasteners

Information

The bolt socket is a special fastener with threads inside and outside, and 4 or 2 bolt keys (below M6) on the outer thread. The products are mainly used in military, aerospace, railway locomotives, vibration machinery and other products that require high thread strength.
From the appearance of the product, the bolt sleeve can be divided into thin-wall type and heavy-duty type. There are also reinforced and extra heavy.
The most basic function of the bolt sleeve is to repair the internal thread and strengthen the external thread. As a thread repair method, the bolt sleeve can quickly and effectively repair damaged threads; when used on low-strength materials, it can greatly enhance the strength of the threaded hole.

Since its development, it has gone deep into aerospace, aviation, and railway machinery. Many different fields and industries such as electronics and electrical engineering. The main feature of the product is that there are 2-4 pre-locking keys on the external thread.

Advantage

• 1: threaded mounting pin sheath may effectively enhance the fastening strength and safety threaded hole, a threaded hole extended periods of time, improve product quality.
• 2: In some spark plugs, molds and other machinery and require frequent removal temperature of the screw holes on the corrosive bolt means threaded screw hole jacket may be enhanced wear resistant-corrosion resistant.
• 3: The bolt thread sheath has a repair function. When the screw thread of the machine's threaded hole slips due to various reasons, use the special tap of the bolt thread sheath for tapping, install the bolt thread sheath, and the threaded hole with the slippery thread 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.
