Loctite 263 threadlockers(roll)

LOCTITE® 263 is a high-strength, red, liquid threadlocker designed to lock and seal heavy-duty metal fasteners up to 1 inch in diameter. This versatile adhesive cures reliably on active and passive metals — including steel, stainless steel, and plated fasteners — even in the presence of minor surface contaminants, oils, or corrosion protection fluids. It delivers permanent vibration resistance, prevents loosening, and seals threads against leakage and corrosion. LOCTITE 263 is ideal for applications requiring maximum strength and heat resistance up to 180°C (360°F), making it suitable for industrial machinery, heavy equipment, and automotive assemblies.
