Description

Version:

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.
HSS one-pass hand tap for through holes.

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).

Note:

  • For suitable plug gauges for thread checking see No. 486000 onwards.
  • Self-locking inserts, inserts with other dimensions and UNC/UNF thread inserts are available on request.

For TiCN coated HSS-E-PM machine taps see No. 133550 and No. 138200.
