TORK CRAFT BOLT LOCK HIGH STRENGTH FOR LARGE SIZED THREADS RED-50g

High-strength thread locking adhesive for permanent heavy-duty fasteningsThe anaerobic adhesive fills gaps between threads and cures only when confined between metal surfaces — creating a solid bond that behaves like a welded or press-fit joint. It effectively prevents loosening under vibration, torque, thermal cycling or repeated stress, ensuring structural integrity and reducing maintenance needs in demanding applications.

Features

• High-strength anaerobic formula — creates a permanent, rigid bond between threaded metal fasteners
• 50 g container — sufficient for several large-bolt assemblies
• Suitable for large bolts, studs and heavy fasteners — ideal for automotive, structural, industrial or heavy-machinery applications
• Works on steel and common ferrous metal fasteners — for maximum joint strength and longevity
• Cures between confined metal threads only — avoids premature curing; bond forms once parts are assembled

Benefits

• Permanent vibration-proof joints: resists loosening under heavy load, shock or continuous vibration.
• Enhanced structural reliability: ideal for critical assemblies in machinery, automotive components, structural frames or load-bearing joints.
• Reduced maintenance frequency: once cured, joints stay secure long-term, reducing need for re-tightening or retorquing.
• Prevents thread corrosion and fretting: fills micro-gaps and locks fasteners to minimize movement and wear over time.
• Cost-effective alternative to welding or mechanical locking devices: secure joints without needing special collars, lock-nuts or complex hardware.

Extra Information

• Ensure bolts and corresponding nuts or threaded parts are clean, dry and free from oil, grease or corrosion before applying adhesive — degrease if necessary.
• Apply a thin layer onto the male threads, then assemble and tighten the fastener as per specification; avoid excessive torque beyond recommended values.
• Allow handling after approx. 30–60 minutes; full bond strength typically develops within 24 hours depending on metal type and ambient conditions.
• Once cured, the bond is considered permanent — disassembly may require heat, mechanical force or use of solvents depending on joint design and maintenance requirements.
• Not recommended for small screws or lightly stressed assemblies — use a medium-strength thread locker for those cases to allow easier removal later.
