- 12-Point with 7/16 in. O.D. Flange Head
- Requires 5/16 in. 12-Point Socket/Wrench for Loosening or Tightening
Premium-Quality Grade 5 Fasteners
Designed to handle more torque than a socket head or hex head screw, JEGS 12-Point Fasteners make 12 points of contact with your wrench while the flange distributes pressure to eliminate the need for a washer. Grade 5 fasteners have a 120,000 psi yield strength making them ideal for components that see moderate stress, e.g., automotive body panels, engine brackets, and some external engine components such as intake manifolds or carburetor mounting.
