Product Overview
The Hex Jam Nut is a specialized, low-profile fastener intended for use as a locking or positioning component in assemblies where space is limited. Typically paired with a standard nut, it creates a friction-based lock to prevent loosening under vibration.
Key Features
Thinner profile than standard hex nuts for space-constrained applications.
Designed to create secondary locking tension on threaded fasteners.
Compatible with standard tooling for easy installation and adjustment.
Available in various materials for different environmental conditions.
Helps maintain preload in assemblies subject to movement or vibration.
