Description

304 SS Slotless Lead Sealing Screws - Tamper Proof Design - Round Head with Hole - Utility Meter Security - M4/M5/M6

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.
