Loctite 37701 Red High-Strength Threadlocker Stick, 9 g, is a wax-based anaerobic adhesive designed to deliver a durable hold on metal fasteners. Built for heavy-duty assemblies where maximum securing power is needed, this red stick bonds to a wide range of metals including stainless steel, aluminum, and plated surfaces. It tolerates oils on threads and light contaminants, helping maintain a reliable lock through temperature fluctuations and routine service. The formula sets quickly—tack in about 10 minutes and full bonding strength in 24 hours—so maintenance and repairs can move forward with minimal downtime. The compact stick format keeps application neat and easy to carry, making it a practical addition to professional service kits and OEM workflows.

Key capabilities

  • High-strength hold designed to resist heavy shock, vibration, and chemical exposure
  • Excellent oil tolerance to maintain adhesion when threads aren’t perfectly dry
  • Effective on stainless steel, aluminum, and plated surfaces
  • Fast initial set: about 10 minutes; full strength in 24 hours
  • Temperature resistance up to 140°F (60°C)

Typical applications

  • Threads on bolts and studs ranging from 6 mm to 19 mm (1/4" to 3/4")
  • Valve cover bolts, water pump bolts, and oil pan bolts
  • Drive shaft bolts, rocker studs, and carburetor studs
  • Caliper brackets, cylinder heads, and other assemblies subject to vibration
  • Heavy machinery and automotive repairs where durable, time-controlled bonding is desired

How to use: Clean the threads, apply a thin film of the threadlocker to the male threads or mating surfaces, assemble, and torque as specified. Allow about 10 minutes for an initial set and plan for full cure after 24 hours for maximum strength. Stored properly, the stick stays ready for upcoming jobs and can be easily carried in a toolbox or service cart.
