Purpose and Specifications

LIQUI MOLY Screw Retainer High Strength 10g (3803) is a premium German-made threadlocker that locks screws, bolts, and nuts in place to stop them from loosening due to engine vibration or road shock. It works on all common fastener sizes up to 3/4 inch and most metals, even oily or galvanized surfaces, sealing threads to prevent leaks.

Key practical benefits:

• Handles extreme temps from -60°C to +150°C - stays secure in freezing winters or hot engine bays.
• Cures fast on active metals like steel or copper (minutes), slower on stainless or aluminum (hours).
• Anaerobic formula hardens without air between tight metal parts for a rock-solid hold.
• Shelf life: 24 months sealed at 8-21°C - store in your garage toolbox.

When to Use / Replace?

Use on critical fasteners like cylinder heads, suspension bolts, or transmission mounts where high strength is needed - lasts the life of the vehicle unless heated to 250°C+ for removal. Replace every 100,000 km or 5 years during major services if exposed to harsh chemicals or extreme wear. Ideal for DIY mechanics or pros fixing vibrating parts.
