Simple, strong, and made to last, OzFDM’s Nyloc Nuts keep every connection secure and every print ready for real world performance.
Lock It Once, Trust It Always
Reliable Grip That Lasts
Every OzFDM Nyloc Nut is made with precision stainless steel and a nylon insert that locks threads firmly in place. Once fastened, the nylon ring grips tightly against the bolt, creating a dependable hold that stays secure even when exposed to movement, vibration, or changing temperatures. This smart locking design prevents loosening over time, ensuring your builds stay stable and strong through repeated use.
Whether you are assembling brackets, enclosures, or mechanical parts that experience stress or motion, these nuts maintain their grip and integrity without the need for constant adjustment. The stainless steel construction resists corrosion and wear, giving each nut long term strength that supports both functional prototypes and production ready builds.
Perfect Fit for Every Build
OzFDM’s Hex Nyloc Nuts are available in a range of sizes from M2 to M6, offering flexibility across countless project types. Designed for precision and ease, each nut threads smoothly and seats securely for a tight, consistent fit every time. From lightweight 3D printed parts to metal assemblies, these nuts pair perfectly with OzFDM’s threaded inserts, bolts, and filament materials like PLA+ and PETG.
Each nut is carefully machined and tested for reliable performance, giving makers confidence that their finished parts will stay aligned and locked in place. Whether you are fine tuning small components or strengthening large assemblies, OzFDM’s Nyloc Nuts provide the strength and precision needed to complete any project with professional quality.
Consistent Results, Effortless Assembly
Installing Nyloc Nuts is simple and effective, requiring only basic hand tools for a clean, secure connection. As the nut tightens, the nylon ring compresses around the bolt’s threads, creating friction that keeps it in position without damaging the material beneath. This easy locking action delivers a neat, flush finish that holds tight through vibration, handling, and daily wear.
From first fit to final use, OzFDM’s Nyloc Nuts help makers achieve smooth, consistent results that last. Whether used for mechanical joints, printed assemblies, or functional repairs, each nut is built for performance that feels effortless but endures under real conditions. Nyloc Nuts are strong, steady, and ready for whatever the project demands.
