Threaded Inserts For Metals

Bollhoff Fastenings Pvt Ltd offers a range of Threaded Inserts for Metals. The advantages include: Kobsert threaded inserts are one-piece fasteners for locking, vibration and torque resistant threads with high strengths, for metals with low shear strength, like aluminium and aluminium alloys, magnesium alloys; the Kobsert is mechanically fixed in place without additional locking pins, adhesive or other additional elements; with Kobsert threaded inserts, damaged threads can be repaired; the Kobsert with sealing ring is designed for gas and liquid leak proofed joints; when installing the threaded inserts, the safety flange is pressed into the surface of the parent material (this reduces the pipe-shaped neck area under the safety flange and covers as far as the mounting thread); after installation into the part, the threaded inserts are reliably protected against unscrewing, even when the part is exposed to dynamic screw load or extreme temperatures. Due to the installation process where the Kobsert body is pulled into the same direction like the screw load, the clearance of the external thread is compensated. The external thread is pre-set properly.
