A Square Head Bolts are low or medium carbon steel, externally threaded bolt, 1/4" diameter or larger, with a trimmed square shaped external wrenching head. Square head bolts were the industry standard prior to hex bolts taking over. A square head bolt has a distinctly shaped head that makes it ideal for working in blind areas. Square head bolts are now normally used in rustic look applications. With the proper tools, tightening a square head bolt is easy even when the fastener is out of your line of vision. The head design of square head bolts enables an easier wrench grip for nut tightening. They are usually used in new construction to mimic an older aesthetic or in railway applications. Square head bolt design enables an easier wrench grip for nut tightening. They are usually used in new construction along with square plate washers and taper washers. These Bolts worked really well in the railroad industry, where supervisors could check that all bolts were on based on whether the head lined up with the tie. It is common in the railroad industry, on electrical panels, and in furniture manufacturing.
Square Headed Bolts Square head bolts offer minimum chance of wrench slippage while wrenching because of their square designed head. They are commonly used in industrial machinery, restorations of village houses to hang rustic decorations to the walls, including some furniture products, such as chairs or computer desks, and some other outdoor needs, such as in gardens, in a garage or in outdoor kitchens etc. A 307 Square Headed Bolts, nickel plated gr 8 Square Bolts, standard hex sizes for bolts can be used for many different applications such as Tower and Pole, Oil and Gas, Furniture and Decoration, Highway Guardrail, Mechanical Machine, High-Speed Rail and train, Solar Energy, Metal Building etc FYFasteners provides all the standard sizes in most ASTM, SAE and DIN specifications, including nonstandard dimensions.

Features Square Head Bolts are similar to Hex Cap screws but have a 4-sided square head instead of a 6-sided hexagonal head. The square head enables an easier wrench grip for tightening and a larger bearing area for gripping. They are commonly referred to as both bolts and screws and are designed to be driven with a wrench. Standards DIN 479
Square Head Bolt Size : M20 to M42 (as per custom requirement) Shear Head Bolt Size : M24 to M42 (as per custom requirement)
The advantages of square head bolts include their large square head design for easy handling with wrenches or other tools, as well as their ability to withstand greater stress without breaking or being damaged, providing high strength and durability. Additionally, square head bolts are long lasting, as they often have a high carbon steel core and are externally galvanized, which helps to prevent rust and corrosion and ensures safety and stability over the long term.

Carriage / Square Neck Mushroom Head Bolts
The advantages of small semi-circular head low square neck bolts mainly include their ability to reduce the concavity and convexity of the surface of the bolt very well, and because of the softer material, they are often used in places where the stress is not very strong. The design of this type of bolt is characterized by setting the neck directly in the groove, which helps reduce the stress concentration in the joint, thus enhancing the stability and reliability of the connection. In addition, due to the design of its head, this type of bolt also has a certain anti-theft effect in the connection, because its head does not have a slot or hexagonal head and other designs that facilitate the application of force, which increases the covertness and safety of the connection. Therefore, small semi-circular head low square neck bolts are suitable for a variety of occasions that require fastening connections, especially in some of the aesthetic and safety requirements of the occasion with high performance is particularly prominent!
