Bollhoff HeliCoil Plus Screw Thread Inserts

HeliCoil Plus thread inserts distinguish themselves through a high wearing tensile strength, low thread friction with tight tolerances, a high surface quality as well as corrosive and heat resistance.

The material and nut thread strength pre-determined performance limits are increased through the internationally tried and tested HeliCoil Plus thread technology.

HeliCoil Plus thread inserts are available in two versions: Free Running and Screwlock. Both variations distinguish themselves due to an optimal design. As with a screw the threaded inserts are simply screwed in by means of a fitting mandrel.

The fitting time is reduced by up to 20% due to the fact that the program of utilisable tools has been so radically extended compared to previous methods of operations. HeliCoil Plus is available for the sizes G, UNC and UNF less and equal 1⁄2 inch. All other sizes are produced as HeliCoil Plus classic.

HeliCoil Plus inserts are fully compatible with others such Emhart Helicoil, Alcoa Recoil Voelkel V-Coil inserts and kits, Armstrong Helicoil, Filtec, Kato Coilthread, Timesert, WTI, PermaThread, Timesert.
