A seized fastener, damaged thread, or scored metal surface can turn a routine assembly step into an avoidable production issue. Galling often begins where metal surfaces are exposed to high contact loads, especially during assembly, press fitting, run-in or maintenance. Once surfaces start to seize, the impact can move quickly from component damage to downtime, rework and delayed production.
MOLYKOTE® G-N Metal Assembly Paste from DuPont helps protect metal components before friction becomes a problem. Available through ChemPoint, this heavy-duty assembly paste is designed for metal-to-metal contact applications where surface protection, low friction and anti-seize performance are important.
Assembly and run-in are critical stages for new or rebuilt equipment. DuPont notes that proper lubrication helps prevent surface damage during initial startup or run-in, particularly in components such as gears, splines, journal bearings, cams and ways. DuPont also states that MOLYKOTE® Speciality Lubricants help prevent chatter and scoring or galling damage during assembly and run-in operations.
MOLYKOTE® G-N Metal Assembly Paste is formulated for demanding boundary lubrication applications. DuPont describes it as an extreme-pressure lubricant for assembly, press fitting, threaded connections, running-in and maintenance, with use in plain bearings, splines, gears, cams and ways.
ChemPoint lists MOLYKOTE® G-N Metal Assembly Paste as a multipurpose, heavy-duty paste that supports galling prevention during run-in, helps extend component lifetime, and protects against fretting wear and corrosion. ChemPoint also describes it as a grease-like lubricant based on mineral oil with solid lubricant additives, including molybdenum disulfide and white solids.
For production and maintenance teams, that makes the paste a practical choice for applications where metal surfaces need protection before equipment reaches full operating conditions.

Metalworking |
Helps prevent galling, welding, and metal pickup during metal-to-metal contact |
Threaded Connections |
Supports screws, bolts, threaded fasteners and connections where anti-seize performance and easier disassembly are important |
Assembly and Run-in |
Supports plain bearings, splines, gears, cams, ways, movable screws, threaded spindles and lead screws |
Maintenance and Repair |
Helps protect components exposed to fretting wear, corrosion and high-load surface damage |
These applications reflect the product’s role as an assembly and run-in paste for metal components that experience friction, load and surface contact during installation or service.
Galling is not just a material issue; it is a production risk. When threads seize, fittings lock or components score during run-in, teams may face damaged parts, slower assembly, difficult disassembly or additional maintenance work.
DuPont states that MOLYKOTE® G-N Metal Assembly Paste lubricates beyond the yield point of most metals in boundary applications, reducing wear and helping prevent seizing, galling and excessive friction. DuPont also notes that its low coefficient of friction supports threaded fasteners by helping convert torque into holding force and reducing the force required for disassembly.
For customers, the value is clear: apply the right paste before high-load contact occurs and help protect the line from friction-related assembly problems.
MOLYKOTE® G-N Metal Assembly Paste gives manufacturers a focused solution for assembly, run-in, press fitting, threaded connections, metalworking and maintenance applications where galling prevention and metal surface protection are important.
