Specification Brand : Walfront BulletPoint1 : Anti-loosening inserts - locking wire screw sleeves can lock the screws into the threaded holes, so that the screws will not loosen when subjected to shock and vibration, which is better than ordinary locking devices BulletPoint2 : Wire Thread Inserts - Also known as Threaded Boots, Stainless Steel Threaded Sleeves, Wire Sleeves and Brackets. It is a new type of internal thread fastener made of high-strength, high-precision -shaped steel wire; BulletPoint3 : Optional Sizes - Thread Repair Kits are available in 5 different sizes, M10 x 1.25 x 1D, M10 x 1.25 x1.5D, M10 x 1.25 x 2D, M10 x 1.25 x 2.5D, M10x 1.25 x 3D. Example: M3 x 0.5 x 1.5D, it means that after the screw group is completed, the internal thread is M3, the pitch is 0.5, and the length is 1.5D (the length is 1.5 times the diameter, that is, 1.5 x 3=4.5mm), the length here refers to installed length. BulletPoint4 : Scope of application - Apply to low-strength engineering materials such as aluminum alloy, zinc alloy, copper, plastic, etc., which can significantly improve thread strength and wear resistance. Commonly used in hydraulic machinery, welding equipment, auto parts, power machinery and furniture and other fields. BulletPoint5 : High-quality 304 stainless steel - 304 stainless steel is not easy to break when repairing threaded holes. The thread size is standard, the thread is clear, and the thread slipping repair is more accurate.
