Applications & Selection Guide

ISO 898-1 property class 4.8 hex head bolts with thread up to the head, dimensioned to DIN 933 / ISO 4017 and ISO metric coarse pitch. Nominal tensile strength 400 MPa (yield ≈ 320 MPa) — the economical choice for light mechanical and non-critical structural joints.

Typical uses include covers, brackets, light frames, cable management, furniture hardware, and general fabrication where pretension is modest. Full thread allows flexible grip length in short clamps. Pair with class 4 or 5 hex nuts; zinc electroplating or hot-dip galvanizing can be quoted for outdoor exposure. Select M×L from the size table above.
