Product Description

The M4*8*8 Screw, also known as M4*8*8 Bolt or M4*8*8 Fastener, is a threaded mechanical component designed for secure assembly in machinery, electronics, and structural applications. Featuring a 4mm nominal diameter, 8mm shank length, and 8mm thread engagement, it provides robust fastening for modules requiring high shear strength and vibration resistance. Suitable for environments with operating temperatures ranging from -30°C to +120°C, this fastener excels in automotive, industrial automation, and robotics sectors. Its zinc-plated steel construction offers corrosion resistance, while the hexagonal head ensures tool compatibility. Advantages include durability, ease of installation, and standardized sizing; limitations involve limited suitability for ultra-high-torque or extreme-temperature scenarios beyond specified ranges.
