A mounting member (1), for a mineral cutting apparatus (2), has an enlarged head (3) incorporating an annular seating shoulder (4), whilst a circular section pin (5) extends integrally from the head (3) and is adapted to be received in a circular section socket (11) of a pick box (12) and to be retained therein, a circumferential groove (16) being provided intermediate the ends of the pin (5) to receive a fluid sealing member (17), with a first portion (24) of the pin (5) being of such diameter that, in use, it is a slide fit within a pick box socket (11), and with a second portion (25) of the pin (5), being of such diameter that, in use, it is an interference fit within a pick box socket (11). The invention also includes a pick box; a mounting member and a pick box combination; a drum for a mineral cutting apparatus; mineral cutting apparatus; a road planing machine; a mining machine, and a tunnelling machine.
