Solutions for fastening problems
Solutions for fastening problems
The success of an assembly rests on many factors. To find the optimal solution we must consider the design and nature of the elements to be joined, the final requirements of the application and the installation parameters. Nevertheless, during the on-site application, we may find problems related to screw performance.
Our engineers have solid experience and extensive knowledge on performance of screw assemblies for industrial applications. Therefore we are aware of any possible problem that may occur for which we suggest the proper solution.

Stop thread failures in die-cast assemblies
Blocking and stripping can occur during assembly into die-cast materials, leading to downtime, higher scrap and rework. CELO fasteners are specially engineered for die-cast materials to speed assembly and improve joint reliability.
Cross-threading and vibration loosening in metal tapped holes
Assembly in pre-tapped holes often faces a dual challenge: preventing vibrational loosening and ensuring precise alignment during installation, especially with soft metal nuts made of copper or aluminum.
Cracking in plastic assemblies
Cracking often results from the wrong fastening approach—especially self-tapping screws. Here’s a better solution for stronger, more reliable joints.
Assembly line efficiency
TORX PLUS® improves assembly line performance and offers excellent cost saving opportunities, being the best system for automatic and semi-automatic feeding lines.
Worker fatigue and assembly inefficiency
Traditional fastening methods in manual and semi-automated assemblies can lead to fatigue, slowdowns, and defects. Our ergonomic solutions make assembly easier and faster.
Stripping off
This problem occurs when the tension generated during tightening is higher than the nut’s shear strength. This can be caused by several circumstances.
Delayed fracture
A delayed fracture takes place when after certain period of time, the screw breaks just at the area were its cover and the base material contact each other.
Screw jamming
When the screw head does seat on the cover material, no clamping force is applied to the assembly. This can be caused by several circumstances.
