M8*20 DIN 933 External Hex Bolts Stainless Steel A2-70 Full Thread Fasteners

Metric hex bolts M8x20
DIN 933 M8x20 bolts
High tensile M8x20 hex bolts
Metric external hexagonal bolts M8*20
Metric hex bolts M8x20 compliant with DIN 933 standard, high tensile strength Grade 8.8 or higher, corrosion-resistant steel material, ideal for industrial machinery and structural applications.

Product Description

The Metric hex bolts M8x20 (DIN 933 M8x20 bolts) are high-strength fasteners designed for industrial applications requiring reliable mechanical connections. These High tensile M8x20 hex bolts are manufactured from grade 8.8 carbon steel, offering a tensile strength of 800 MPa and a yield strength of 640 MPa. With ISO 898-1 compliance and hot-dip galvanized surface treatment, they provide corrosion resistance for outdoor or humid environments. The full-threaded design enables adjustable clamping across machinery, automotive, and construction sectors. Measuring 8mm in diameter and 20mm in shaft length with a 13mm hexagonal head, they operate effectively within -50°C to +150°C temperature ranges. While excelling in load-bearing structural assemblies, their carbon steel material requires additional coatings for prolonged exposure to acidic conditions compared to stainless steel alternatives.
