What Is a Round Head Bolt?
A round head bolt is a type of fastener characterized by its round head and the absence of tool engagement features such as Phillips, flat head, or hexagonal recesses. These bolts are distinguished by the square shapes beneath their heads, which mesh with corresponding grooves on the fastened part, allowing for secure attachment without the need for a tool to hold the bolt itself.
Uses of Round Head Bolts
Round head bolts are commonly used in construction, particularly in applications where screws need frequent tightening, such as scaffolding assembly. Their design allows for efficient use, requiring only one tool for fastening, thus saving time and effort.
Principle of Round Head Bolts
The principle behind round head bolts lies in their rectangular neck shape, designed to mesh with square or elongated holes in the fastened parts. This design secures the bolt in place during fastening, allowing for easy positioning and tightening.
How to Select Round Head Bolts
When selecting round head bolts, consider their size, tolerance, strength classification (4.8, 8.8, or 10.9), and the dimensions of the square shape's root angle. Ensure the long hole in the fastened part matches the bolt's specifications, taking into account the corner radius to avoid misalignment.
Other Information on Round Head Bolts
How to Tighten and Loosen Round Head Bolts
Round head bolts are specifically designed for construction use, offering advantages such as the ability to be secured in a square hole, preventing rotation during fastening, and their tamper-resistant head design. Unlike hexagon socket button bolts, which are used in industrial applications and require a hexagonal wrench for fastening, round head bolts provide a secure and tamper-proof solution for various construction and assembly applications.
