- Controlled M12 Fastener Friction
Product Description
MOLYKOTE P-3700 Anti-Seize Paste is a dark-gray, high-purity mineral-oil paste with special solid lubricants for bolted joints exposed to elevated temperatures. The formulation contains no intentional calcium, lead, nickel, sulfur, chlorine, or fluorine and is suggested for high-chromium and stainless alloys. Typical data include a 3,000 N four-ball weld load, 280 to 320 unworked penetration, and controlled thread/head friction values for defined M12 fastener systems. The paste is applied to cleaned, fully coated screws, nuts, and bolts, while its solid lubricants resist temperatures from -30 to 900 deg C.
Key features
- High-Purity Solid Lubricants: The formulation contains no intentional calcium, lead, nickel, sulfur, chlorine, or fluorine.
- 3,000 N Weld Load: The four-ball weld-load result is measured by DIN 51350, Part 4.
- Controlled Fastener Friction: M12 fastener tests provide thread, head, and K-factor values for blackened and stainless systems.
Applications / Suitable for
- Screws, nuts, and bolts in elevated-temperature industrial equipment.
- High-chromium alloy bolted joints.
- Stainless-steel anti-seize applications.
