Titanium lock washers

Titanium lock washers are critical mechanical fasteners designed to prevent loosening caused by vibration, torque, and thermal expansion in high-stress assemblies. Manufactured from aerospace-grade titanium alloys, such as Grade 5 (Ti-6Al-4V) or commercially pure Grade 2, these washers provide a specialized solution for environments where weight reduction and corrosion resistance are paramount. Unlike standard steel fasteners, titanium lock washers maintain their tensioning capabilities in extreme temperatures and aggressive chemical exposures. Their primary function is to increase friction between the fastener head and the substrate, or to utilize a spring-like tensioning effect to secure the bolted joint against axial loads and dynamic forces.

Core Technical Advantages

01
Density-to-Strength Ratio
Titanium offers approximately 60 percent of the density of stainless steel while providing comparable or superior tensile strength, facilitating lightweight engineering.
60% density of steel
02
Non-Magnetic Properties
The paramagnetic nature of titanium allows these washers to be utilized in sensitive electronic environments and medical imaging equipment like MRI machines.
fully non-magnetic
03
Thermal Stability
These components maintain mechanical integrity at temperatures ranging from cryogenic levels up to 400°C (752°F).
-200°C to 400°C
04
Bio-compatibility
The inert nature of the material prevents adverse reactions in medical and food-processing applications.
ISO 10993 compliant

Storage and Technical Maintenance

M1
Storage Conditions
Store in a dry, indoor environment. While titanium is corrosion-resistant, keeping the fasteners in their original packaging prevents surface contamination and mechanical damage to the locking teeth.
M2
Galling Prevention
Titanium fasteners are prone to galling (cold welding) during installation. It is recommended to use a high-quality anti-seize lubricant on the threads and washer interface during assembly.
M3
Torque Calibration
Ensure that torque values are adjusted for the specific friction coefficient of titanium, which differs significantly from carbon steel or aluminum.
M4
Inspection Notice
For wedge-locking or serrated versions, inspect the contact surfaces after removal. If the locking teeth show signs of flattening or deformation, the washer should be replaced to ensure joint security.
