Inert Thread Locking

Also known as prevailing torque, this process uses a mechanical force to create a secure lock that is resistant to vibration, shock, and related slippage. The fastener can typically be removed and reused.

• ND Patch, thread-lock coating fused to threaded fasteners
• ND Patch Hi-Temp, thread-lock coating fused to threaded fasteners. Up to 260 deg C.
• ND Pell-It, thread-lock insert in drilled fasteners is self-sealing, reusable and adjustable
• ND Pell-It Soft Touch Tip inserted in set screw or bolt ends to cushion and hold
• ND Strip, Nylon (and other materials) inserted in milled threaded fasteners: locks, seals & is adjustable
• Vibra-Tite VC-3's viscous cold flow properties prevent fastener loosening under extreme vibration

Reactive Thread Locking

Once installed into a mating part, a strong chemical bond is formed, preventing slippage from shock and vibration while helping to seal fastening points against gas and liquid leakage.

• Epoxy-Lock's powerful locking and sealing features remain inert until the coated fastener is installed
• Expand-A-Seal threadlocking and sealing compound expands up to 50% in volume
• ND Microspheres Acrylic threadlocking room-temperature-cure adhesives
• ND Microspheres Epoxy threadlocking room-temperature-cure adhesives
• ND Microspheres TA threadlocking room-temperature-cure adhesives

Masking & Lubricating

Formulated to ease the assembly process and to protect fastening parts against exposure to undesirable substances that can adhere to uncoated fasteners.

• Anti-Seize 917N fastener lubricant prevents high-temperature galling
• EZ Drive300 reduces installation torque on thread-forming fasteners
• ND LM 1293 Thread masking and lubricating PTFE-material reduces friction
• Specialty Coatings are paints, lubricants, and high-performance finishes used in a wide variety of applications
• ND WaxLube synthetic thermoplastic reduces friction in thread-forming fasteners

Advanced Sealing

ND pre-applied sealants are designed to withstand a wide range of pressures, chemical fluids and gases while reducing the chance of a fastener loosening.

• Biseal 0630 wax-based material seals sheet-metal holes on fastener installation
• ND Expandable Mastics create heat-activated seals expanding up to 400%
• ND Crushable Mastic Sealer fills gaps and voids around fasteners
• Plastisol Applied-to-Metal improve on O-rings; Open-Mold alternative to injection molding
• ST-3 thread sealant and locking compound

Assembly Aids

Designed to make assembly safer, easier and faster by reducing application errors and worker fatigue.

• Stay-Put fastener retention speeds assembly & reduces inventory
• ND Color Code adds easy identifiers to heads or tips of fasteners
• DriveGrip creates a positive grip between fastener and tool increasing strength by up to 700%
