Square Bolts, also known as square head machine bolts, feature a four-sided head designed to provide a firm and convenient grip for a wrench during installation and tightening. The square head design is particularly useful in applications where a secure tool grip is required.
Square head bolts have been used extensively in traditional construction and engineering applications and are still selected today for heavy-duty fastening, restoration projects, and structures where a classic or industrial appearance is preferred. They can also be used to match existing fasteners in older structures.
Adore Industries manufactures and supplies Square Bolts in different sizes, materials, standards, and surface finishes. Customized square head dimensions and special requirements can also be accommodated for specific projects.

Square Head Design
The square head provides four flat sides for wrench engagement, making it convenient to apply tightening torque during installation. This design was widely used before hexagonal head bolts became more common and remains useful for applications requiring a traditional fastener appearance or compatibility with existing square-headed fasteners.
Square Bolts may also be selected for projects where the fastener needs to complement the visual style of an older or heritage-style structure.
Manufacturing & Forming
Square Bolts can be manufactured using hot forging and cold forging processes. The appropriate forming method depends on factors such as bolt size, material, head dimensions, and production requirements.
Special tooling can also be developed for non-standard square head dimensions according to customer drawings and project specifications.
