3M™ Fastener Adhesives 2510/2510N

Epoxy adhesives best suited for normal and high-temperature environments with high-torque installations

2510 (orange) and 2510N (neutral) 3M™ Fastener Adhesives are micro-encapsulated adhesives that cure at room-temperatures. These adhesives improve the anchorage of threaded fasteners. The shearing action of the fastener into a nut or threaded object allows the capsules to break and starts the curing process. Applications of the 2510 and 2510N include engine compartments and safety-related parts.

3M Fastener Adhesives 2510 and 2510N are designed for applications where the service temperature might reach continuously up to 149°C (300°F) or intermittently up to 204°C (400°F).


  • High torque values on coated fasteners
  • Environmental resistance (to heat, automotive fluids, vibration, thermal and mechanical shock)
  • Extended shelf life (bulk adhesive and coated fasteners)
  • Controlled re-activity (adhesive activates and cures upon insertion)
  • Re-usability (additional capsules break with each re-insertion)
  • Allows controlled application to fasteners (viscosity can be adjusted to achieve target coating weights)
  • Penetrates oil coatings
  • Fast drying
  • Bonds to a broad range of fastener finishes
