(19) In practice, the pins are introduced in the same way as the previously described procedure, by they must protrude beyond the opposite wall by 6-8 mm; the difference is in the screwing of the "ARUM" nut: first it is screwed as the reduction stress is increased so its conical part penetrates between the fracture edges; then the pin is cut; and the nut is unscrewed so the cut end of the pin will be included in the space of its base.
(20) Eight conical holes drilled in the side of the chamber serve for the insertion of plugs with attachments for perfusion, rapid injection of small amounts of reagents, temperature measurements or for heating the interior of the chamber.
Countersink
Definition:
(v. t.) To chamfer or form a depression around the top of (a hole in wood, metal, etc.) for the reception of the head of a screw or bolt below the surface, either wholly or in part; as, to countersink a hole for a screw.
(v. t.) To cause to sink even with or below the surface; as, to countersink a screw or bolt into woodwork.
(n.) An enlargement of the upper part of a hole, forming a cavity or depression for receiving the head of a screw or bolt.
(n.) A drill or cutting tool for countersinking holes.
