The Reacon Square Head Machine Bolt is a mechanical fastening component designed for joining and securing compatible parts in industrial, utility, and equipment assembly applications. It features a square-shaped head and a threaded shank, providing a practical fastening structure for applications requiring a stable bolted connection.
Compared with other fasteners, the square head machine bolt has a distinctive head design that allows it to be gripped with a suitable wrench during installation and removal. Its threaded section is designed to work with a matching nut or compatible threaded component, helping hold connected parts together after tightening. The bolt can be selected according to the dimensions, thread requirements, and mechanical conditions of the intended assembly.
The square head is one of the defining features of this machine bolt. Its four flat sides provide accessible gripping surfaces for installation tools, allowing the fastener to be tightened or loosened during assembly and maintenance.
This head configuration is useful in mechanical connections where a conventional wrench can be applied to the bolt head. The square profile also gives the product a recognizable appearance among different types of industrial fasteners.
When selecting a suitable bolt, users should consider the available installation space, head dimensions, and the tools required for the assembly. These factors help ensure that the bolt can be installed properly without interfering with surrounding components.

The threaded shank allows the square head machine bolt to work with a compatible nut or threaded component. During installation, the bolt passes through prepared holes in the connected parts, and the matching nut is tightened on the opposite side to create a clamped connection.
The thread specification is an important factor in achieving proper compatibility. Bolt diameter, thread pitch, thread length, and overall bolt length should be checked against the assembly drawing before ordering.
Different projects may require different thread configurations and dimensions. Reacon can discuss product specifications according to customer drawings, samples, and technical requirements.
For applications where additional corrosion protection is required, the square head machine bolt can be supplied with a hot-dip galvanized surface finish. The zinc coating helps protect the steel substrate from environmental exposure and reduces the risk of corrosion during service.
Galvanized fasteners are commonly considered for outdoor installations and environments where components may be exposed to moisture and changing weather conditions. The actual service life depends on the coating condition, environmental exposure, installation method, and maintenance conditions.
For projects requiring ASTM A153, the coating requirements should be confirmed according to the applicable standard and supporting inspection documentation. The compatibility between the galvanized bolt and its matching nut should also be considered to ensure proper assembly.
Square head machine bolts are used in different mechanical fastening arrangements where their dimensions and mechanical properties meet the requirements of the connection.
Typical application areas may include:
Metal Structure Assembly: Used to connect compatible metal plates, structural components, and supporting parts.
Industrial Equipment Installation: Suitable for fastening equipment components, mounting parts, and mechanical assemblies.
Utility Hardware Assembly: Can be considered for compatible power utility hardware and related installation structures.
General Mechanical Connections: Used in bolted connections where a threaded fastener and matching nut are required.
The specific application should always be determined by the product drawing, load requirements, and installation conditions. Selecting the correct bolt dimensions and mechanical grade is essential for achieving a suitable connection.

Q1: What is a square head machine bolt?
A1: A square head machine bolt is a threaded fastener with a square-shaped head, generally used with a matching nut to secure connected components.
Q2: What is the difference between a machine bolt and a lag screw?
A2:A machine bolt generally passes through prepared holes and works with a matching nut, while a lag screw is designed to engage directly with timber.
Q3: Can square head machine bolts be galvanized?
A3:Yes. Hot-dip galvanizing can be provided according to the agreed product specifications and project requirements.
Q4: Can Reacon provide customized bolt sizes?
A4:Yes. Different bolt dimensions and thread configurations can be discussed based on customer drawings or samples.
Q5: What information is needed for a quotation?
A5:Customers can provide bolt dimensions, thread specifications, material requirements, surface treatment, quantity, and technical drawings if available.
