Claims

[Scope of utility model registration request]

(1) In a flanged bolt consisting of a head having a rotating means, a flange-shaped seat portion having a diameter larger than the head and integral with the head, and a threaded shaft portion having a thread formed on the outer periphery, the flange-shaped The flange-like seat is inclined downward so that the tightening seat surface formed by the lower surface of the seat forms an acute angle with respect to the axis of the screw shaft, and the head member is the upper surface of the flange-like seat. A flanged bolt characterized by a series of circumferential grooves formed near the root.

(2) In the flanged bolt described in paragraph 1,
A flanged bolt characterized by having serrations formed on the tightening seat surface of the flange-shaped seat.
