Universal Bolt Insert

UNBThe Universal Bolt Insert  is a revolutionary steel insert that allows the use of both countersink and cap head bolts. The cylinder fits on the flat bottom of the insert; the cone lies on the slanted outer walls.

According to Finite Element Analysis models and ISO 130 strength tests performed by our laboratory, hold strength increases by up to as much as 300 percent. By spreading the internal stresses in the hold more evenly around the bolt hole, the UBI technology decreases the pressure at the bottom and spreads it to the sides of the hold, making FICTION holds stronger than ever.

The insert is now integrated into all FICTION bolt-on holds.
