Description
Version:
HSS machine taps, straight flutes, 4-turn lead chamfer for through holes or blind holes with deep-drilled tapping hole in tolerance class 6H.
High-strength HeliCoil®plus thread inserts for through bolts, of stainless steel with high wear-resistance, low thread friction in close tolerances, high surface quality as well as corrosion and heat resistance. The flexible construction allows an even distribution of load and tension forces and thus allows creation of very high quality permanent screw connections with ideal force transfer for all working loads (static, dynamic). Uncomplicated quick insertion, resulting in an internal thread that can be used from both ends.

Application:
For economic repair of damaged or worn threads and as a design element for thread reinforcement in materials which have low shear strength (e.g. aluminium, aluminium-magnesium alloys).
