JPH07208431A - Galvernized iron bolt - Google Patents

Abstract

PURPOSE:To facilitate nut tightening without damaging the screw thread by forming a sandwiching surface through the means of cutout, for sandwiching it by a tool, on the threaded end portion of a galvernized iron bolt, which has a hook formed on its lower part, in the same direction as the hook. CONSTITUTION:A sanwiching surface 2 for sandwiching it with a pair of pliers or the like is formed by cutout on a threaded end portion 1 of a galvernized iron bolt, which is formed with a hook 3 on its lower part, in the same direction as the hook 3. When an opaque galvernized iron sheet or the like is secured with a galvernized iron bolt, the sheet galvernized iron or the like can be easily secured because the direction of the hook 3 can be judged from the threaded end portion 1 even if the hook 3 is invisible. A nut can be easily tightened without damaging the threaded portion because the surface to be sandwiched is sandwiched with a pair of pliers or a tool of the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION In the present invention, even if a hook is inserted into a hole such as an opaque galvanized galvanized iron sheet, the direction of the hook can be judged from the tip screw portion. The present invention also relates to a galvanized bolt that does not damage the threaded portion of the tip screwed portion with a tool such as pliers.

[0002]

2. Description of the Related Art Conventionally, when fixing an opaque galvanized iron or the like with a galvanized bolt, if a hook is inserted into a hole of the galvanized iron or the like,
The direction of the hook cannot be determined from the tip screw part. Further, since the tip screw portion has no gripping surface, when the tip screw portion is pinched with a tool such as pliers, the screw portion may be damaged.

[0003]

[Problems to be Solved by the Invention]

I. When fixing opaque galvanized iron etc. with galvanized bolts,
When the hook was inserted into the hole of galvanized iron, there was an inconvenience that the direction of the hook could not be judged from the tip screw part. B. If the tip screw part was pinched with a tool such as pliers, the screw part could be damaged. The present invention has been made to solve the above drawbacks.

[0004]

[Means for Solving the Problems] A sandwiching surface which is sandwiched by a tool such as pliers in the same direction as the hook (3) on the tip screw portion (1) of a galvanized bolt having a hook (3) formed at the bottom. The notch (2) was formed. The present invention is a galvanized iron bolt having the above structure.

[0005]

When the opaque galvanized iron or the like is fixed with the galvanized iron bolt, the direction of the hook can be judged by inserting the hook into the hole of the galvanized iron or the like. Further, even if the pinching surface of the tip threaded portion is pinched with a tool such as pliers, the threaded portion is not damaged.

[0006]

EXAMPLES Examples of the present invention will be described below. A galvanized iron bolt having a hook (3) formed at a lower portion was formed with a notch at a gripping surface (2) to be gripped by a tool such as pliers in the same direction as the hook (3) in the same direction as the hook (3).

[0007]

EFFECTS OF THE INVENTION Since the tip screw portion of the galvanized iron bolt is provided with a holding surface in the same direction as the hook, even if the hook is not visible, the direction of the hook can be judged from the tip screw portion, so that the galvanized iron etc. can be easily fixed. You can do it. Further, since the holding surface is sandwiched by tools such as pliers, the nut can be easily tightened without damaging the screw portion.
