Product Description

The M20x150 half thread bolt is an external hex bolt designed to DIN 933 standards, featuring a partial threading length of 75mm and a smooth shank of 75mm. With a nominal diameter of 20mm and total length of 150mm, this External hex bolt M20 offers a hexagonal head width of 30mm and height of 13mm for secure wrench engagement. Typically manufactured in grade 8.8 steel or A2/A4 stainless steel, it operates effectively in temperatures from -50°C to +300°C, ideal for heavy machinery, structural assemblies, and automotive applications. The DIN 933 M20x150 bolt combines high tensile strength (up to 800 MPa for steel variants) with corrosion resistance in stainless versions. While providing reliable load-bearing capacity, the half-thread design limits adjustability compared to full-thread bolts. Surface treatments include galvanization or plain finish, with optional thread-locking coatings. Its precision-machined ISO metric thread ensures compatibility with standard M20 nuts and flanged connections.
