Genuine tamper-proof slotless lead sealing screws. 304 stainless steel, no drive slots, round head with Ø1.8mm hole. Sizes: M4x12mm to M6x25mm. Passivated finish. Custom lengths. IEC 62055 compliant.
Revolutionize meter security with true slotless lead sealing screws featuring zero drive slots and a precision-drilled vertical hole (Ø1.8mm) in the round head. Machined from A2-70 stainless steel (304), these screws eliminate all tool-gripping surfaces, forcing would-be tamperers to destroy the seal for removal. The passivated finish resists corrosion in outdoor electrical enclosures.
