At Bossard, we believe that our holistic view, Proven Productivity, is key to getting ahead with you, through developing solutions that are more efficient and cost-effective.
Threaded fasteners are commonly used to facilitate assembly and disassembly of multiple mechanical parts. However, when undergoing transverse vibrations, threaded fasteners may experience self-loosening and fatigue, two common failures which can lead to disastrous accidents.
Understanding the magnitude of failures due to self-loosening, Bossard provides a diverse range of anti-loosening solutions to prevent bolting assembly failures. Irregardless of size, bolting failures in threaded fasteners can be disastrous incidents. These incidents may include compromises in workplace safety leading to injuries and death, or disruption and downtime to assembly lines leading to loss of business. Listed below are some of our product solutions. The product images shown are for illustration purposes only.

Product Solutions for the Electric-Bike
The customer is a strategic partner to the World’s Top Two-Wheel Vehicle Maker, that developed battery-swapping solutions for urban electric scooters, mopeds and motorcycles.
Customer Pain Points
- Safety concerns were raised by the customer during Reliability Tests on the e-scooters
- Fastener loosening was detected at ‘exit motor enclosure’ due to high vibrations encountered during operations
Opportunity
- While studying the existing assembly, the root cause was found to be linked to an unsecured socket-head fastener assembly
- Screws with an internal drive and small head height often have the disadvantage that the material recess for the drive leads to a weakening of the screw head
Action
- Bossard proposed ecosyn®-grip combines the wide contact surface of a button socket head with locking teeth which help keep the fastening assembly locked in place
- ecosyn®-grip is a unique solution where the socket head fastener has an In-Built Anti-Loosening function – serrations under bolt head which help keep the fastening assembly locked in place with the customer’s expectations during initial reliability tests
What are the benefits ?
- With ecosyn®-grip, issues relating to vibrational loosening were effectively resolved
- Assembly time of the sub-components improved by 38%
- Overall Cost Savings of 30% have been achieved as a result of ecosyn®-grip implementation
