Execution: High-strength, free-running HeliCoil®plus threaded inserts made of stainless steel with high wear resistance, low thread friction in tight tolerances, high surface quality, as well as corrosion and heat resistance. The flexible design allows for uniform load and stress distribution, creating permanent screw connections of the highest quality for all operational loads (static, dynamic) with ideal force transmission. Simple, quick assembly results in a gage-holding, double-sided usable internal thread. Complete repair kit for one metric thread size in a plastic case. Note: TiCN coated HSS-E-PM machine taps. Suitable limit gages for thread inspection. Self-locking inserts, other dimensions, and UNC/UNF threaded inserts are available upon request. Delivery includes: 1 spiral drill, 1 pin breaker. Use: For economical repair of damaged or worn threads and as a construction element for thread reinforcement when using materials with low shear strength (e.g., aluminum, aluminum-magnesium alloys).
