Product Description

The M20x60 hex bolts are half thread hex bolts designed to DIN 931 standards, featuring a 20mm nominal diameter and 60mm total length with a threaded portion of approximately 30mm for adjustable fastening and a 30mm unthreaded shank for enhanced shear resistance. These high-strength hex bolts, made from grade 8.8 carbon steel, offer tensile strength up to 800 MPa and are surface-treated with zinc plating for corrosion resistance, suitable for temperatures ranging from -50°C to +150°C. Ideal for structural engineering, automotive assembly, and heavy machinery applications, they provide reliable clamping force and easy installation via standard 30mm hexagonal heads. While their partial threading allows precise tension control in dynamic loads, prolonged exposure to corrosive environments may require additional protective coatings. Compatible with DIN 934 nuts, these bolts support standardized industrial connections across construction and manufacturing sectors. Customizable surface treatments (e.g., hot-dip galvanizing) are available for specialized requirements.
