Forch K121 Thread Lock is designed for the high-strength permanent locking and sealing of threaded fasteners. It cures in the absence of air and ensures the perfectly secure fitting of threaded components, making it ideal for heavy machinery and critical applications. Its formulation resists vibrations, impacts, and extreme temperatures, ensuring long-lasting durability and performance. This versatile thread lock can be applied to almost any type of metal, securing bolts, screws, and other fasteners to prevent loosening due to vibration and mechanical shocks.
Viscosity (25°C): 400-600 mPas; Density (25°C): 1.1 g/cm³; Temperature resistance: -55 °C to +150 °C; Max. gap filling: 0.15 mm; Breakaway torque: 28-35 Nm; Shear strength (DIN 54452): 15-20 N/mm²; Touchable consistency: 10-20 min; Functional consistency: 1-3 h; Final consistency: 5-10 h; Max thread: M20.
For best results, ensure that the threads are clean, free from oil, and contaminants. Although Forch K121 can harden on unclean surfaces, cleaning will enhance bonding strength. Apply a few drops of the product onto the fastener thread and tighten as required. The product will start to set within minutes and achieve full functional strength within 1-3 hours and full cure within 5-10 hours. Special tools or heating to +300 °C are required to disassemble.
Prevents loosening from vibrations and impacts; High temperature resistance; Ideal for use on bolts, screws, and nuts for a long-lasting hold; Provides secure fitting for safety-critical applications; Hardened connections can be disassembled with special tools or heat.
1. Clean the threads of all dirt and oil. 2. Apply a few drops of the thread locker to the fasteners. 3. Assemble the parts and tighten as required. 4. Allow the product to set for 10-20 minutes before handling. 5. The bond will achieve functional strength in 1-3 hours and full cure in 5-10 hours.
Ideal for automotive, industrial, and heavy machinery applications. Suitable for bolts, screws, and nuts up to M20 thread size.
Forch K121 Thread Lock High Strength Red 50ml is a premium-grade additive designed for securing and sealing threaded connections that normally do not need to be released. It is vibration and impact resistant, providing outstanding media and heat resistance. The product hardens even in unclean surfaces, although the cleaner the surface, the stronger the connection. Its high-strength formulation can only be released using special tools or by heating to +300 °C. Key parameters include: Viscosity (25°C): 400-600 mPas, Density (25°C): 1.1 g/cm³, Temperature resistance: -55 °C to +150 °C, Max gap filling: 0.15 mm, Breakaway torque: 28-35 Nm, Shear strength (DIN 54452): 15-20 N/mm², Touchable consistency: 10-20 min, Functional consistency: 1-3 hours, Final consistency: 5-10 hours, Max thread: M20.
