12-Point Flange Nuts: Overview & Key Features

Featuring a 12-sided (dodecagonal) exterior, 12-point flange nuts deliver superior grip and torque capability when compared with conventional hex nuts.
Material & Finish Options
Typically crafted from high-strength steel or stainless steel, these fasteners offer exceptional durability and rust resistance. They are available with protective surface treatments-such as zinc plating and black oxide-to further minimize wear and enhance corrosion protection.
Flange Functionality
The integrated flange acts as a built-in washer, distributing clamping force across a wider surface area to safeguard underlying materials and ensure a stable, reliable fit.
Primary Advantages
Superior Torque Delivery
With 12 engagement points, your socket or wrench achieves maximum contact, allowing for higher tightening force while minimizing the risk of stripping or rounding off the edges.
Enhanced Hold
The expanded contact surface provided by the flange creates greater friction, helping prevent the fastener from backing out or loosening under vibration.
Tight-Space Accessibility
The 12-point geometry allows tools to engage at finer angles, making installation and removal significantly smoother in cramped or hard-to-reach locations.
Streamlined Assembly
By eliminating the need for a separate washer, the built-in flange simplifies assembly and speeds up installation workflows.
