The ROBXC4X35 presentation contains 25 Bossard 3646129 screws with a low cylindrical head, hex socket, M4 metric thread and 35 mm nominal length. They belong to the BN 17 range and are manufactured to DIN 7984, with approximate equivalence to UNI 9327.
The low head is 7 mm in diameter and 2.8 mm high, reducing the space occupied above the mounting surface. The drive uses a 2.5 mm hex key and the socket is 2.3 mm deep. The screw is made from blue zinc-plated steel.
Bossard identifies the property class as 08.8 / 8.8 and states that the head marking is decisive. The item may be supplied partially or fully threaded; on the partially threaded version, thread length b is 14 mm, but this version cannot always be guaranteed. Owing to the head geometry, the fastener has reduced loadability in accordance with ISO 898-1.
