Dykem Cross Check Torque Indicating Paste: Identify Fastener Movement in Critical Applications

Improve Fastener Inspection and Quality Control with Torque Seal

When a fastener is installed, knowing that it was properly tightened is only part of the equation. In many industrial applications, it is equally important to identify whether that fastener has moved after installation.

Dykem Cross Check torque indicating paste provides a simple, visible method for identifying potential fastener movement. Applied across a fastener and the adjoining surface after tightening, Cross Check creates a witness mark that serves as a visual reference during subsequent inspections.

If the fastener rotates relative to the surface, the mark may crack, separate, or become misaligned, alerting inspection personnel that the connection requires further evaluation.

From aerospace maintenance and automotive service to general industrial machinery and amusement park equipment, Dykem Cross Check is a valuable tool for visual fastener inspection and preventive maintenance.

How Does Dykem Cross Check Work?

Cross Check is commonly used as a torque seal or witness-marking compound. It does not measure torque directly. Instead, it creates a visible reference mark after a fastener has been tightened according to the applicable procedure.

The process is straightforward:

1. Install the fastener. Tighten the bolt, nut, or other threaded connection to the specified torque using the required tools and procedure.

2. Apply the witness mark. Place a line of Dykem Cross Check across the fastener and the adjacent stationary surface.

3. Allow the mark to dry. Follow the product's application and drying instructions before exposing the mark to service conditions.

4. Inspect for movement. During subsequent inspections, look for a broken, shifted, cracked, or misaligned witness mark that could indicate relative movement.

This simple marking method makes it easier to identify connections that may need closer inspection without dismantling equipment or checking every fastener immediately.

Important: An intact witness mark is not proof that a fastener remains at its specified torque. If a mark is disturbed, the connection should be evaluated according to the applicable maintenance or inspection procedure.

Aerospace Fasteners: A Critical Application for Torque Indicating Paste

Aerospace maintenance requires careful attention to fastener installation, inspection, and traceability. Bolted connections are found throughout aircraft structures, equipment assemblies, access panels, and many other components.

Witness marks provide maintenance personnel with a convenient visual reference that can help identify potential fastener movement between inspections.

For aerospace applications, however, product selection must account for material compatibility, approved processes, and applicable engineering requirements.

Dykem Cross Check is available in an aerospace-approved version specified to meet Boeing Material Specification BMS 8-45H, Type III. This version is intended for applications where the relevant aerospace specification is required.

Always verify the current manufacturer's documentation and the applicable aircraft maintenance instructions before using a marking compound on aircraft hardware. A specification claim should not be interpreted as blanket approval for every aircraft, component, or application.

Automotive Service and Fastener Inspection

Automotive technicians routinely work with threaded fasteners on vehicles, machinery, and related equipment. Depending on the application, identifying possible fastener movement can be an important part of inspection and maintenance.

Dykem Cross Check can be used to create visible reference marks on suitable fasteners after installation.

Potential applications include:

• Engine and drivetrain assemblies where witness marking is specified

• Chassis and suspension components where permitted by the service procedure

• Equipment mounting hardware

• Industrial vehicle and fleet maintenance

• General automotive service and repair operations

Witness marks can help technicians quickly identify connections that warrant additional investigation. They should always be used in conjunction with the vehicle manufacturer's torque specifications and maintenance procedures.

General Industrial Applications: Make Fastener Inspection Easier

Industrial equipment often contains numerous bolted connections that must remain secure throughout operation. Machinery vibration, thermal cycling, maintenance activity, and other operating conditions can make fastener inspection an important part of a preventive maintenance program.

Dykem Cross Check can help maintenance teams establish a visible reference on selected connections.

Industries and applications may include:

• Manufacturing machinery and production equipment

• Pumps, motors, and mechanical assemblies

• Industrial equipment mounting hardware

• Material-handling systems

• Electrical and equipment enclosures

• Maintenance, repair, and overhaul operations

By standardizing how selected fasteners are marked, maintenance departments can make visual inspection more consistent and help identify connections that require further investigation.

Amusement Parks: A Visible Inspection Aid for Safety-Critical Equipment

Amusement park rides and attractions contain mechanical assemblies, structural connections, and equipment that require rigorous inspection and maintenance.

In these environments, maintenance personnel need reliable procedures for checking critical components and identifying potential problems before equipment returns to service.

Torque indicating paste can support those procedures by providing visible witness marks on designated fasteners.

Potential uses include selected mechanical assemblies, equipment mounting points, and other connections where witness marking is authorized by the manufacturer or engineering team.

For amusement park applications, Cross Check should be treated as one element of a broader inspection program—not a substitute for required torque checks, nondestructive examinations, scheduled maintenance, or regulatory inspections. Only use the product where the equipment manufacturer's requirements and the approved maintenance procedure permit it.

Dykem Cross Check Is Available in Eight Colors

Choosing a suitable color can make witness marks easier to identify during routine inspections. Dykem Cross Check is available in eight colors, giving maintenance and quality-control teams options for different inspection programs and visual identification requirements.

Color coding may help organizations distinguish between equipment groups, inspection stages, maintenance departments, or other categories when supported by a documented procedure.

For example, a facility might establish different colors for separate inspection programs. The specific meaning of each color should be defined by the organization rather than assumed by individual technicians.

When selecting a color, consider:

• Contrast against the fastener and surrounding material

• Visibility under the site's normal lighting conditions

• Consistency with existing maintenance and inspection procedures

• Compatibility with the product's intended application
