Specification Brand : Hilitand BulletPoint1 : SUS304 stainless steel: Use high-strength, high-precision -shaped cross-section steel wire This product is also called threaded sheath, stainless steel threaded sleeve, wire sleeve, which is a new type of internal threaded fasteners, practical, high hardness, and non-deformation. BulletPoint2 : Efficient maintenance: The use of wire thread inserts can easily switch between metric and inch threaded holes, which is very convenient and fast. When a thread error occurs or a damaged female threaded hole is repaired, repair the threaded hole in a cost-effective manner. BulletPoint3 : Easy to use: Mainly used for a variety of low-strength materials to help improve the wear of bolted connections and avoid thread damage. Threaded inserts can be used to repair exposed threaded holes. Fixing the screw in the screw hole of the workpiece made of aluminum alloy and other materials can form a high-strength and high-precision standard internal thread. BulletPoint4 : Repair connection: The threaded thread repair insert can enhance the connection strength and improve the connection conditions, prevent the screws from loosening and falling off due to various vibrations and fatigue fractures, and improve the fatigue strength of the threaded connection. Greatly prolong the life of the thread and make the thread softer for basic parts. BulletPoint5 : Application: Thread insert kits are widely used in low-strength engineering materials, such as aluminum alloys, zinc alloys, alloys, copper, plastics, engineering plastics, etc. DriveSystem : Cross ExteriorFinish : Zinc FinishType : Finish ItemName : Hilitand 50Pcs Thread Inserts Set, SUS304 Stainless Steel Wire Thread Inserts Assortment Kit Thread Inserts for Metal M5/16‑18‑2.5D ItemPackageDimensions_Height : 2 centimeters ItemPackageDimensions_Length : 8 centimeters ItemPackageDimensions_Width : 7 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : threading-inserts Manufacturer : Hilitand MetalType1 : Stainless Steel MetalType2 : Aluminum MetalType3 : Alloy Steel MetalType4 : Copper NumberOfItems : 1 PartNumber : Hilitandco752hxmsu324 ProductDescription : Specification: Item Type: Thread Inserts Material: SUS304 Model: M5/16182.5D Purpose: Threaded connection Outside Diameter Before Installation: Approx. 9.6 ~ 10.2mm / 0.4 ~ 0.4in Length After Installation: Approx. 19.9mm / 0.8in Diameter of Drilling Drill Bit for Installation: Approx. 8.3mm / 0.3in Thread Protective Sleeve Model Specification Description: For Example: M3x0.5X1.5D, which means that after the screw set is completed, the female thread is M3, the pitch is 0.5, and the length is 1.5D (length refers to 1.5 times the diameter, that is, 1.5x3=4.5mm ), the length here refers to the length after installation.
