About Structural Adhesives

Retaining Compounds for Close-Fitting Parts

Fill gaps up to 0.01" to secure unthreaded cylindrical metal parts such as shafts, bearings, and press-fit assemblies.

Retaining Compounds for Oily Close-Fitting Parts

Even on oily surfaces, these retaining compounds keep their hold.

Retaining Compounds for Oily Loose-Fitting Parts

Even on oily surfaces, these retaining compounds keep their hold.

Retaining Compounds for Loose-Fitting Parts

Fill gaps up to 0.02" to secure worn unthreaded cylindrical metal parts such as shafts, bearings, and press-fit assemblies.

Threadlockers

Threadlockers for Plastic Fasteners

Specially formulated for plastics, these threadlockers secure nylon, PTFE, and other plastic threaded fasteners.

Threadlockers

Prevent threaded fasteners from loosening due to shock and vibration.

Lubricating Threadlockers

These low-friction threadlockers harden slowly, allowing ample time to smoothly adjust multiple large bolts for even clamping.

Quick-Set Threadlockers

These threadlockers develop usable strength within one hour. Because they harden quickly on most metals, they don't require a primer.

Adjustable Threadlockers

Use these threadlockers on fasteners that require occasional fine-tuning, such as set screws.

Threadlockers for Drinking Water

These threadlockers meet NSF/ANSI 61 for drinking water.

Heavy Duty Threadlockers

Withstand demanding, high-vibration applications such as motor and pump housings with these threadlockers.

High-Temperature Threadlockers

Keep threaded fasteners from loosening at temperatures up to 450° F.

High-Temperature Threadlocker Paste

This thick paste withstands temperatures up to 650 °F.

Threadlocker Gel

This gel clings to fasteners to prevent drips.

Adjustable Wicking Threadlockers

Use these threadlockers for threaded fasteners that require occasional fine-tuning, such as set screws.

High-Temperature Wicking Threadlockers

These threadlockers withstand temperatures up to 450° F.

Wicking Threadlockers

Apply these threadlockers on fasteners that are already installed—their thin consistency allows them to flow into small gaps.
