Product Description

The Metric hex bolt M8x22 is a standardized fastener designed for robust mechanical assembly, featuring an external hexagonal head (External hex bolt M8-22) for wrench compatibility. With a nominal diameter of 8 mm, a thread length of 22 mm, and a head height of 5.3 mm, it conforms to ISO 4014/ DIN 933 specifications. Constructed from grade 8.8 steel or A2/A4 stainless steel, it offers tensile strengths up to 800 MPa and operates in temperatures from -50°C to +150°C. Surface treatments include galvanized, zinc-plated, or plain finishes for corrosion resistance. Widely used in automotive, machinery, and structural applications, the M8x22 hex head bolt excels in high-stress environments due to its torque resistance, dimensional precision, and compatibility with standard tools. Key advantages include ease of installation, standardized sizing, and vibration resistance, though proper tightening torque must be maintained to prevent thread stripping.
