SPL Hex Flanged Nut M14-M27, Spiralock Wedge Thread Self-Locking Nut

The SPL hex flanged nut is a fastener integrating the functions of a nut and a washer. It adopts a hexagonal design for easy tightening with wrenches. The integrally formed bottom flange (collar) enlarges the bearing area, distributes pressure and protects the workpiece surface. Self-locking and anti-loosening performance is achieved by the Spiralock wedge thread structure, ideal for vibration-prone working conditions.

Key Features

• Integrated Structure: Built-in flange eliminates the need for separate washers and simplifies assembly procedures.

• Pressure Bearing & Self-locking: The enlarged contact surface evenly disperses clamping pressure to prevent workpiece damage. Combined with Spiralock wedge self-locking thread, it delivers stable anti-loosening performance under vibration.

• Easy Installation: Hexagonal profile fits standard wrenches and sockets for convenient mounting and disassembly.

Main Specifications

• Reference Standard: GB/T 6170 and other relevant fastener standards

• Material Grade: Stainless steel A2-70 as standard option; other materials available upon request

• Size Range: Thread size M14~M27, including key dimensions such as across-flat width and nut height

• Surface Finish: Stainless steel natural finish, zinc plating, Dacromet and other options for different service environments

Application

Widely applied in automotive manufacturing (chassis and body fastening), mechanical equipment, steel structure connections and other scenarios requiring high clamping force and vibration-resistant locking.
