A kind of high abrasion hexagon-headed bolt for automobile, including bolt head and screw rod, the height for automobile are resistance to
Mill hexagon-headed bolt is an integral molding structure, and the high abrasion hexagon-headed bolt for automobile is steel alloy material；
The bolt head is hexgonal structure, and the screw rod is round bar shape, the right side of the bolt head and the screw rod
Left end connects, and the left-hand face intermediate member position of the bolt head is recessed with cross groove, the right side of the screw rod
Also there is screw thread, the right-hand end of the screw rod to be also extended with shackle member, the shackle member structure in a circular table shape on surface；
It is also recessed with annular groove in the left-hand face of the bolt head, the inner wall of the annular groove is in thread-like structure, institute
State the outside that annular groove is located at the cross groove.
Further, the left side of the bolt head is also screwed with protective cover, and the protective cover is cylindrical shape, the protective cover
Inner wall be in thread-like structure, the side of the protective cover is in closed, and the other side of the protective cover is opening-like, the guarantor
The open end of shield is screwed on annular groove by screw thread.
Further, position is also recessed with the first groove among the right end face of the shackle member, and first groove is
Circular configuration；The right side of the shackle member is also protruding with several clamping blocks, and several clamping blocks are rounded to be arranged and be uniformly distributed in
The right end face of shackle member；The trapezoidal structure of clamping block.
Further, the right side of the bolt head is also protruding with step surface, and the diameter of the step surface is more than the screw rod
Diameter.
The utility model has the advantage of：
The utility model uses steel alloy material so that hexagon-headed bolt hardness is higher, and non-deformability is strong, improves six
The service life of hex bolt；Hexagon-headed bolt is susceptible to abrasion in use, is recessed at hexagon-headed bolt
Cross groove can not disassemble to avoid because wearing so as to cause bolt, can be by Philips screwdriver to bolt
It is dismantled；Also be screwed on protective cover outside hexagon-headed bolt, can be given birth to avoid cross groove through exposing to the weather
The case where rust；Several clamping blocks protruded at shackle member can improve the fastening ability of bolt, and bolt is avoided pine occur because skidding
It is dynamic.
