B8X-290 Penetrating Threadlocker

B8X-290 solves the challenge of securing already-assembled fasteners without disassembly. Its ultra-low viscosity enables rapid capillary action into tightly mated threads, making it ideal for instrument screws, electrical connectors, and small mechanical assemblies. Once cured in the oxygen-free environment between metal surfaces, it provides reliable medium-high strength retention while remaining serviceable with standard hand tools.

Key Technical Specifications

Note: Breakaway torque is lower than prevailing torque—typical of wicking formulations where full thread coverage may vary.

Performance Highlights

• Wicks into Pre-Assembled Joints: No need to disassemble; apply at thread interface and let capillary action do the rest.
• Seals Micro-Leaks: Fills porosity in castings, powder metal parts, and weld seams.
• Medium-High Strength: Secure enough for vibration-prone environments, yet removable with hand tools.
• Ideal for Precision Assemblies: Perfect for electronics, instrumentation, and small mechanical systems.

Typical Applications

• Electrical terminal blocks and connector screws
• Instrument panel fasteners
• Small motor housings and sensor mounts
• Porous metal components (cast aluminum, sintered parts)
• Maintenance retrofits on inaccessible bolts

Application Guidelines

• Clean area around joint to remove grease or debris for optimal wicking.
• Apply a drop at the thread interface; allow 5–10 minutes for full penetration.
• Full cure in 24 hours; handling strength in ~20 minutes.
• Disassemble using standard hand tools—no heat required.
• Store upright at room temperature (<25°C); keep cap sealed.

Available in 20 ml (workshop/trial) and 250 ml (production) bottles.
