Bolt adapted for many types hand tools to work with

Abstract

A screw bolt able to be turned by the manual tools different in size and type features that the peripheral edge of its bolt head is composed of two short straight edges and two long arc edges for adapting the different open spanner, and a recess made on the top surface of said bolt head has an edge consisting of 6 arc edges and 6 straight edges, which are alternative, for adapting to hexagon spanner and quincunx hexagon spanner.

Description

technical field [0001] The invention relates to a bolt, which refers to a bolt that can be turned and rotated by hand tools of different sizes and types, and provides convenience for operators to select hand tools during operation. Background technique [0002] In daily life, bolts are the most commonly used locking and connecting methods, and the shape of the bolt head can roughly tell the force that the bolt can withstand. Generally, it is turned with a cross or a straight screwdriver Round head bolts have a small bearing capacity and are commonly used in household electrical appliances; hexagonal flat head or concave hole bolts have a large bearing capacity and are commonly used in various industrial products such as machinery, automobiles and motorcycles. They have a wide range of applications and are suitable for There are also many hand tools, such as open-end wrenches, socket wrenches, fixed wrenches, hexagonal wrenches, and plum blossom hexagonal wrenches.

[0002] In daily life, bolts are the most commonly used locking and connecting methods, and the shape of the bolt head can roughly tell the force that the bolt can withstand. Generally, it is turned with a cross or a straight screwdriver Round head bolts have a small bearing capacity and are commonly used in household electrical appliances; hexagonal flat head or concave hole bolts have a large bearing capacity and are commonly used in various industrial products such as machinery, automobiles and motorcycles. They have a wide range of applications and are suitable for There are also many hand tools, such as open-end wrenches, socket wrenches, fixed wrenches, hexagonal wrenches, and plum blossom hexagonal wrenches. Diversification, however, nowadays only a single-sized bolt with a certain specification of hand tools can be turned without damaging the service life of the bolt

[0003] The most common troubles encountered by ordinary operators when turning the rotating bolt are that the hand tool is not correct, and the second is that the size does not match. Therefore, it is often necessary to understand the tool type first and choose different sizes many times before finding a hand tool that meets the specifications. in vain inconvenience and distress
