Medium Strength

PERMATEX Medium Strength Thread Locker is a blue anaerobic adhesive designed for mechanics and enthusiasts who need reliable fastener security without permanent bonding. This medium-strength formula is ideal for applications such as reassembling engine blocks, securing oil pan bolts, and locking down suspension components. It provides a balance between holding power and future disassembly, making it essential for serious automotive work.

As an anaerobic adhesive, PERMATEX Medium Strength cures in the absence of air and requires metal contact to harden. The blue color allows for easy identification of treated fasteners during assembly and teardown. This formula offers sufficient holding torque for engine, transmission, and drivetrain work while still allowing disassembly with standard hand tools when service is needed.

Mechanics rebuilding engines, upgrading suspensions, or performing transmission work rely on this formula for fasteners experiencing moderate stress and vibration. It is compatible with bolt sizes ranging from 1/4" to 1" diameter and works well on steel, stainless steel, and plated fasteners. The compact bottle ensures controlled dispensing on each fastener without waste.
