- Controlled M12 Fastener Friction
Product Description
MOLYKOTE P-74 Assembly Paste is a grayish-black, PAO-based, metal-free assembly paste with graphite and white solid lubricants for anti-seize and lubricating applications. The paste carries a typical 4,800 N four-ball weld load and has a service range of -40 to 200 deg C; selected raw materials continue to act as separating agents at 1,500 deg C in the dry-lubricant state. Applications include bolted connections, sliding bearings, linear guides, splined shafts, press-fit joints, exhaust and spark-plug threads, flanges, hinges, and brake mechanisms.
Key features
- Metal-Free Anti-Seize Formulation: PAO base oil is combined with graphite and white solid lubricants without metallic solids.
- 4,800 N Weld Load: The four-ball weld-load result is measured by DIN 51350, Part 4.
- Controlled Fastener Friction: An M12 grade 8.8 test produced 0.14 thread and 0.08 head friction coefficients.
Applications / Suitable for
- Bolted and threaded connections.
- Sliding bearings, linear guides, and splined shafts.
- Press-fit joints, flanges, hinges, and brake mechanisms.
- Exhaust bolts and spark-plug threads.
