Wire screw sleeve — product description and key benefits What it does Reinforces and repairs threaded holes in lowstrength materials by inserting a hardness wire sleeve into the damaged or weak hole. Restores original thread form and allows reuse of the existing fastener without increasing hole diameter. Why you need it Prevents further wear and damage to workpieces by taking the contact wear on the sleeve instead of the base material. Simplifies maintenance: damaged or stripped threads can be repaired quickly by installing a sleeve, avoiding costly rework or replacement of parts. Improves joint reliability under load and vibration, reducing the risk of fastener loosening and fatigue failure. Key benefits Wear resistance: The sleeve material is harder than the mating screw, so the sleeve resists wear and allows repeated assembly and disassembly. Load distribution: The sleeve's elastic properties help equalize load across thread flanks, reduce local stress concentrations, and compensate for minor pitch or tooth deviations. Vibration damping and fatigue resistance: Elasticity absorbs vibration and increases thread connection strength and fatigue life. Positive locking option: Lockingtype wire screw sleeves secure the screw in the threaded hole to prevent loosening under shock and vibration, offering better retention than standard locking devices. Spaceefficient: Delivers stronger connections without enlarging the screw hole or changing bolt diameter. Features and compatibility Function: Thread reinforcement, thread , and optional locking retention. Compatibility: Designed for use in lowstrength base materials and wherever thread life or thread is required. Works with standard threaded fasteners when the appropriate sleeve size is used. Material and performance: Uses a higherhardness wire coil sleeve that is wearresistant, elastic enough to distribute load and absorb vibration, and suitable for repeated use. Maintenance: Simple installation into damaged holes; replacement of the sleeve is straightforward if worn. Typical applications Repairing stripped or damaged threads in machinery housings and cast components without replacing the part. Securing fasteners in vibrationprone equipment (engines, pumps, industrial machinery) using the lockingtype sleeve to prevent loosening. Reinforcing threads in assemblies that require frequent disassembly (access panels, service fixtures, maintenance equipment). Technical note Select the correct sleeve size and type for the existing thread pitch and diameter to ensure proper fit and function. Installation restores thread integrity and extends component life without altering the workpiece geometry.
