Product Description

These M3x6 metric hex bolts feature a 3mm diameter and 6mm length, designed for precise fastening in mechanical assemblies requiring compact hardware solutions. Constructed from grade 4.8 steel with zinc-plated corrosion resistance, they operate across industrial temperature ranges (-20°C to +120°C). The external hex head enables torque transmission via standard 2.5mm wrench/socket. Applications include electronics enclosures, machinery subassemblies, and automotive components where space-constrained M3 hex head bolts 6mm length prove ideal. External hex bolts M3-6mm offer vibration resistance through optimized thread engagement but require careful installation to prevent head stripping in soft materials. Maximum torque capacity of 0.6Nm ensures reliable fastening for lightweight structural connections without deformation. Packaging options support bulk industrial or small-quantity prototyping requirements.
