Product Description

The Half Thread Hex Bolt M12 (M12x120 External Hex Bolt) is a 120mm-long hex head bolt with a partial threading design, suitable for applications requiring adjustable clamping force. Featuring a 12mm diameter shaft and a 120mm total length, it combines a threaded section for secure fastening and a smooth shank for structural alignment. Constructed from high-grade steel (common grades 8.8 or 10.9), it offers tensile strengths up to 1000 MPa, with optional corrosion-resistant coatings (zinc, galvanized). This external hex bolt operates in -30°C to +150°C environments, widely used in machinery, automotive assemblies, and structural frameworks. Key advantages include easy torque application via hexagonal head and versatility in semi-permanent installations. Limitations include reduced thread engagement compared to full-thread bolts. Complies with DIN 933/ISO 4017 standards for dimensional accuracy.
