MAR-LOC™
Self-Locking, Marsden-Type Free-Spinning Locknut
The MAR-LOC™ is an all-metal fastener designed to provide a secure and reliable locking mechanism for various applications. This locknut is engineered to turn freely on a bolt until it is firmly seated against a base. Upon further tightening, the nut deforms into the threads of the bolt, creating a self-locking action that prevents loosening due to vibration or dynamic loads. This design ensures a durable and maintenance-free connection, eliminating the need for additional locking components.
Application
MAR-LOC™ locknuts are suitable for a wide range of applications, including:
- Automotive Industry: Securing components subject to constant vibration and movement.
- Machinery and Equipment: Maintaining the integrity of assemblies in industrial machines.
- Aerospace Sector: Providing reliable fastening solutions in high-stress environments.
Specifications
Materials
Available in steel grade 8, various alloys, and stainless steel to suit different environmental conditions and strength requirements.
Threads
Offered in UNC, UNF, or 8UN Series, Class 2B, 3B, left-hand thread, and Metric to accommodate diverse threading standards.
Installation
The installation process for the MAR-LOC™ locknut is straightforward:
Threading
Manually spin the locknut onto the bolt until it contacts the bearing surface.
Seating
Continue to tighten the locknut until it is firmly seated against the base.
Locking
Apply additional torque to deform the nut into the bolt threads, activating the self-locking mechanism.
This method ensures a secure and permanent fastening without the need for supplementary locking devices.
