Abstract

A prefix soket head cap screw, including the nail body, wherein, nail body top is provided with the polished rod, and the polished rod upper end is provided with the conical head to hexagonal groove in being provided with in the conical head, and be provided with a prefix at the conical head upper surface, in addition, the opening angle of conical head is 90, when the hexagon socket head of screw damaged, hexagonal inslot in inserting extracting tool through a prefix can be dismantled the screw that damages fast, the nail body sets up the operation requirement that satisfies the machine and carry nacelle, external thing flap fastening simultaneously, and conical head less prominent fastening surface, is difficult for skidding in the use, is convenient for dismantle the screw that damages fast.

Description

Flat head socket head screw
Technical field
The utility model relates to airborne technical field of fastening, particularly relates to a kind of flat head socket head screw.
Background technique
The socket head screw that current domestic aircraft pod or store Combinations lid use, its minimum diameter of thread at more than 6mm, comprise national military standard and navigation mark all lack the diameter of thread below 6mm can bear meet aircraft pod, store Combinations lid fastening requirements screw optional; The socket head screw head simultaneously used now is mainly cylinder type, and screw head is thicker, and when the hexagon socket head of screw damages, extracting tool easily skids in hexagon socket head, is difficult to the screw disassembling will damaged fast.
Model utility content
The technical problem that the utility model solves is to provide a kind of flat head socket head screw, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
Flat head socket head screw, comprises rivet nut, wherein, is provided with polished rod above rivet nut, and polished rod upper end is provided with conehead, and in conehead, be provided with interior hex slot, and conehead upper surface is provided with flat head; In addition, the opening angle of conehead is 90 °.
In the utility model, be provided with the transition conical surface, and rivet nut upper end is provided with transition cambered surface below polished rod, polished rod is connected with the transition cambered surface that rivet nut upper end is arranged by the transition conical surface.
In the utility model, rivet nut is round column structure.
In the utility model, the diameter of thread of rivet nut is less than 6mm.
In the utility model, polished rod is round column structure.
In the utility model, conehead comprises symmetrically arranged two semicircle cambered surfaces.
In the utility model, flat head width is 1 ~ 2mm.
In the utility model, when screw hexagon socket head damages, in extracting tool is inserted by flat head in hex slot, the screw disassembling that can will damage fast; Simultaneously rivet nut arranges and meets the fastening usage requirement of aircraft pod, store Combinations lid, and the outstanding fastener surface of conehead, in use not easily skid, be convenient to the screw disassembling that will damage fast.
Beneficial effect: the utility model by arranging conehead above rivet nut, and is provided with interior hex slot in conehead, and conehead upper surface is provided with flat head; And the opening angle of conehead is 90 °, when the hexagon socket head of screw damages, in extracting tool is inserted by flat head in hex slot, the screw disassembling that can will damage fast; Simultaneously rivet nut arranges and meets the fastening usage requirement of aircraft pod, store Combinations lid, and the outstanding fastener surface of conehead, in use not easily skid, be convenient to the screw disassembling that will damage fast.
