12 Point Flange Bolts

12-Point Flange Bolts

12 point bolts and nuts have an elective head structure than standard hex association top screws. The twelve point plan yields more perceptible torque to be related with the screw which executes changing of the hex association that can happen with catch of this type.12 Point rib locks are usually utilized on vehicles plots. They are utilized wherever hex washer head stuns are utilized. These stuns have teeth under their head that hold the mating surface, which helps in repudiating evacuating. 12-point spine stuns are utilized in transporter and helper moving vehicle applications.
