M10 x 1.25 Locking Flange Nuts (10)

The M10 x 1.25 Locking Flange Nuts are engineered for applications demanding secure, vibration-resistant fastening in mechanical assemblies, automotive work, and industrial machinery. This 10-piece set provides the reliability needed when standard fasteners risk loosening under stress, impact, or thermal cycling. Whether you're rebuilding an engine, assembling heavy equipment, or performing critical maintenance, these locking nuts prevent fastener migration that could lead to component failure or dangerous downtime.

Manufactured from cadmium-plated steel, the M10 x 1.25 Locking Flange Nuts feature a 12 mm hex head and serrated flange design that generates mechanical resistance under the bolt head. The serrated flange bites into the mounting surface, creating friction that locks the nut in place without compromising the fastener's reusability or requiring chemical locking compounds. The cadmium plating provides corrosion resistance, making these nuts suitable for both indoor and moderately exposed environments where durability and longevity matter.

These M10 x 1.25 fasteners excel in automotive restoration, engine rebuilds, machine assembly, and anywhere vibration isolation is critical. The serrated flange design is particularly effective in applications where parts experience constant micro-motion or thermal expansion and contraction. Installation is straightforward with any standard metric socket set—no special tools or surface preparation required. For maximum security, pair these locking nuts with appropriately rated metric bolts and tighten to your equipment's specified torque value.
