TH TSF SYSTEM FOR PULLED UNIONS THAT GUARANTEES 75% PRELOAD WITH LESS THAN 5% DISPERSION According to joint characteristics, we define the location of the contact zone for optimizing the pressure and the cone strength distribution. CERTIFIED BY

TH Reduced number of fastening elements with respect to torque control (25-35% less It can be designed as standard sized parts or according to different designs adapted to any specific application from M-12 up to M-150. It is suitable for assembly with standard pullers equipment. Low dispersion. High stability of the preload. Low load distribution factor for the fastening element. Lower fatigue range. Insensitivity to bending moments Simultaneous assembly of fastening elements. Elimination of elastic interaction of close elements. Benefits of elongation, without the disadvantages of friction. Multiple reuse of the element. Ease preload reset by assembly process repetition. Self-locking result. Same assembly protocol for all metric sizes. Depending on each union characteristics a different assembly protocol will be followed. Every specific union would be object of its own engineering analysis.

SECURITY BOLT AND NUT SOLUTION AGAINST EXTERNAL ATACKS

SECURITY BOLT AND NUT The special geometry allows the design of countless number of different combinations for dissasembly keys. Due to this feature it also becomes reusable. Perfect for solar panels, public furniture, automotive wheels,…

SB THE SOLUTION FOR SHEAR JOINTS The shear bolt absorbs conventional manufacturing tolerances of holes and unlike the standard spring pin, it maintains contact between pieces with preload, thereby transmitting shear loads.

OTHER SECTORS Thanks to the tools available and our success in their implementation in both the automotive and wind energy sectors, we are able to supply our best service in fasteners and other products according to our customer requirements, based on integral traceability, to any other industrial sector that requires or would like to incorportate them, using the advantates that our activity offers, like aeronautics, petrochemical, nuclear, civil engineering, railway, shipbuilding…
