With these benefits, the M6/BN124 DIN439 Screws & Fasteners by Bossard meet the highest demands of industrial-grade fastening.

Applications of Screws & Fasteners by Bossard

The Screws & Fasteners by Bossard are widely applied in high-vibration, space-restricted, and pre-assembled environments:

Machinery and Equipment Assembly
Automotive and Engine Systems
Renewable Energy Infrastructure
Electrical Panels and Enclosures
Construction Fixtures and Industrial Frames
Robotics and Motion Control Assemblies

Thanks to their standardized thread profile and low-profile hex form, the Screws & Fasteners by Bossard are essential in secure and stable fastening systems.

Installation and Assembly Overview

The M6/BN124 DIN439 jam nut is designed for simple and effective mechanical locking:

Thread the standard nut onto the bolt to secure the part
Add the DIN439 jam nut and tighten against the first nut
Use two wrenches to counter-lock the nuts (tighten one against the other)
Verify torque and mechanical holding force

This dual-nut locking method helps prevent loosening due to vibration or thermal expansion.

Use Case Scenario: Vibration-Resistant Mounting in Industrial Motor Base

Scenario: A mechanical design team needed a slim fastening solution for mounting electric motors onto a frame without space for full-height nuts.

Problem: Standard M6 nuts caused clearance issues and loosened over time from vibration.

Solution: The M6/BN124 DIN439 Screws & Fasteners by Bossard offered a low-profile, secure jam nut option that stayed tight under dynamic conditions.

Result: Improved reliability, eliminated fastener failures, and maintained structural integrity under vibration.

This example proves why Bossard’s fasteners are trusted across precision engineering tasks.
