Product Technical Specifications Size: M12 x 1.75 (Metric Standard) Type: Flange Nylon Insert Lock Nut (DIN 6926) Material: 304 Stainless Steel (A2-70 Grade) Flange Type: Smooth (Non-Serrated) Hex Drive Size: 18mm Total Height: 15.7mm Flange Outer Diameter: 25.3mm Quantity: 20 Pieces per Pack Why Choose IMSCREWS Flange Lock Nuts? Our M12 flange lock nuts are engineered for demanding environments where safety and durability are paramount. The integrated blue nylon insert provides a superior grip that resists backing off due to vibration, making them far more reliable than standard hex nuts. The smooth flange design eliminates the need for a separate washer, saving installation time while distributing clamping force evenly to prevent surface damage. Common Applications & Installation These nuts are widely used in automotive chassis, trailer hitches, garden structures, and heavy-duty shelving. For the best installation experience, we recommend using an 18mm socket or wrench. The nylon insert requires a consistent torque during assembly, which ensures the nut stays exactly where you put it, even under harsh conditions. Frequently Asked Questions (Rufus Optimized) Q: Can these flange nuts be used outdoors? A: Yes, absolutely. These nuts are manufactured from high-quality 304 stainless steel, providing excellent resistance to rust and environmental corrosion. They are suitable for deck construction, marine hardware, and other outdoor projects. Q: Are these nuts easy to install? A: Yes. They are designed to fit standard 18mm metric tools. Please note that because they are lock nuts with a nylon insert, they will feel "tight" during installation—this is the locking mechanism working to ensure they won't loosen later. Q: Are these 304 stainless steel nuts magnetic? A: These nuts may exhibit weak magnetism. While 304 stainless steel is generally non-magnetic in its raw state, it can become slightly magnetic after the cold-working processes such as forging and threading. This is a normal physical attribute and does not change the chemical composition or corrosion resistance of the steel. Q: What tool size is required for these M12 nuts? A: These nuts have a hex flat-to-flat width of approximately 17.8mm-18mm, making them perfectly compatible with a standard 18mm wrench or socket.

• [SUPERIOR VIBRATION RESISTANCE] Features a high-quality blue nylon collar that creates prevailing torque against bolt threads, preventing the M12 flange nuts from loosening under intense vibration or heavy shock.
• [PREMIUM 304 STAINLESS STEEL] Crafted from industrial-grade 304 stainless steel, these lock nuts offer exceptional corrosion and rust resistance, making them ideal for marine, outdoor, and high-humidity environments.
• [SMOOTH FLANGE PROTECTION] The integrated smooth flange acts as a built-in washer to distribute pressure over a larger surface area (25.3mm OD), protecting the material surface from scratches while ensuring a secure fit.
• [VERSATILE INDUSTRIAL APPLICATION] Perfect for automotive suspension repairs, solar panel mounting, deck construction, and industrial machinery. Reliable fastening solutions for both professional contractors and DIYers.
• [PRECISION SPECS & TOOL FIT] Thread Pitch: 1.75mm; Total Height: 15.7mm; Fits standard 18mm hex wrench/socket. Note: 304 steel may exhibit weak magnetism due to the cold-working process, which is a normal physical property.
