Product Description

The M5.5x40-2# Screw, also referred to as M5.5x40-2# Bolt or M5.5x40-2# Fastener, is a robust threaded component designed for heavy-duty mechanical connections. With a nominal diameter of 5.5 mm and 40 mm length, it supports direct integration into industrial modules requiring secure fastening. Operates reliably across a temperature range of -40°C to +120°C and withstands voltage fluctuations up to 600V in electrical environments. Ideal for automotive, construction, and machinery sectors due to its corrosion-resistant alloy composition. Features a 12 mm hexagonal head for tool compatibility, though installation requires torque calibration to avoid material stress. Limited to applications requiring M5.5 threading specifications. No integrated electronics, battery, or screen components included. Delivers 80 Nm clamping force for stable structural assemblies.
