Info	All thread lengths are guide values only and may deviate. Due to the unfavourable head geometry these fasteners have reduced loadability. Steel fasteners with reduced loadability are marked with a '0' preceding the property class mark, e.g. '010.9'. Stainless steel fasteners with reduced loadability are either marked with a '0' preceding the property class mark, e.g. 'A2-070', or with the steel grade only, e.g. 'A2'.
