Overview
The 248 Adhesive Threadlocker Stick is a specialized anaerobic adhesive formulated to lock threaded fasteners permanently. It is widely used in industries where vibration or thermal expansion could cause mechanical fasteners to loosen over time. The adhesive cures in the absence of oxygen, forming a durable polymer that bonds metal threads securely. This product is favored for its convenience in stick form, which allows precise application without spills or waste. Its high-strength properties make it suitable for critical applications in automotive engines, aerospace assemblies, and heavy machinery.
Physical and Chemical Properties
The 248 threadlocker exhibits a viscous, paste-like consistency in its uncured state, adapting easily to threaded surfaces. Once applied, it cures at room temperature when confined between metal parts, achieving full strength within 24 hours. The cured adhesive resists temperatures up to 150°C (302°F) and demonstrates excellent chemical resistance to oils, fuels, and industrial solvents. Its anaerobic nature ensures that curing only occurs in the absence of air, making it ideal for threaded assemblies. The adhesive’s density and viscosity are optimized for gap-filling, ensuring reliable performance even in imperfectly mated threads.
Main Applications
This threadlocker is primarily used to secure fasteners in high-stress environments. In the automotive sector, it locks critical components like cylinder head bolts, transmission parts, and wheel nuts. Aerospace applications include rotor assemblies and engine mounts, where vibration resistance is paramount. Industrial machinery manufacturers rely on it for gearbox bolts, hydraulic systems, and conveyor equipment. The adhesive’s resistance to thermal cycling and corrosive fluids makes it a versatile solution across sectors requiring long-term fastener integrity.
Safety and Storage
While the 248 threadlocker is generally safe when used as directed, proper handling is essential. Avoid prolonged skin contact, as uncured adhesive may cause irritation. Use gloves and work in ventilated areas to minimize inhalation risks. Store the adhesive sticks in their original packaging, away from heat sources and moisture, to prevent premature curing. Disposal should comply with local regulations for chemical waste. Unused product should not be exposed to air for extended periods, as partial curing may occur. Always refer to the safety data sheet (SDS) for detailed precautions.
B2B Procurement Guide
For bulk procurement, prioritize suppliers with certifications like ISO 9001 to ensure consistent quality. Specify requirements such as cure speed (e.g., medium or high strength) and operating temperature range. Industrial buyers should request technical datasheets and batch testing reports to verify performance metrics. Consider purchasing in stick cartridges for assembly-line efficiency or in larger containers for cost savings. Negotiate pricing tiers based on annual volume, and confirm lead times to align with production schedules. Partnering with distributors offering technical support can streamline integration into manufacturing processes.
