All the pliers in the Supreme Series have an exclusive nut and screw joint. Thanks to the specially designed flush head nut, Lindström’s nut and screw joint strikes the perfect balance between the long term performance of the traditional screw joint and perfect tip alignment of the box joint. - All Lindstrom Supreme Series pliers are ESD safe. Resins with conductive additives in the handles create a material that safely dissipates electrostatic charges, reducing possibility of damage to sensitive components.
