Product Description

The M4x55 hex socket screws, also known as Cylindrical head cap screws or Allen key screws M4-55, feature a 4mm diameter and 55mm length with ISO 4762 standard compliance. Designed for high-torque applications, these screws require a 3mm Allen key for installation and offer a cylindrical head profile for flush mounting. Their zinc-plated steel construction ensures corrosion resistance, suitable for operating temperatures ranging from -20°C to 120°C. Commonly used in machinery assembly, automotive components, and industrial equipment, these fasteners provide secure connections in confined spaces. Key advantages include precise torque transmission, durability under vibration, and space-efficient design, though their deep socket requires proper tool alignment. The 55mm shaft length accommodates medium-thickness materials while maintaining structural integrity.
