Applications & Selection Guide

ISO 898-1 property class 10.9 hex head bolts, fully threaded to DIN 933 / ISO 4017. Alloy steel, quenched and tempered to 1000 MPa nominal tensile strength (yield ≈ 900 MPa) for high-preload and compact high-load joints.

Choose class 10.9 where joint design needs higher clamping force or a smaller diameter under heavy load — machine tools, presses, hydraulic equipment, and critical structural connections. Always mate with class 10 nuts; confirm any electroplated or organic coating is compatible with the heat-treated substrate (hydrogen embrittlement risk on high-strength fasteners). Catalog M×L sizes are listed above.

Include sizes, quantities, coating requirements, and destination in your quote request.
