Types of 7/16″ Bolts
Hex Bolts
Hex bolts are the most commonly used type of bolt. They feature a hexagonal head that allows for easy tightening with a wrench. These bolts are versatile and can be used in various applications, including construction and machinery assembly. You can find a wide range of hex bolts at platforms like McMaster-Carr and Bolt Depot.
Flange Bolts
Flange bolts are designed with a circular flange under the head, which acts like a washer to distribute the load. They are particularly useful in applications where a large surface area is beneficial, such as in the automotive industry. Bolt Depot offers a variety of flange bolts suitable for different uses.
Carriage Bolts
Carriage bolts have a rounded head and a square neck that prevents them from turning when tightened. They are commonly used in wood applications, such as furniture assembly or deck building. Their design provides a secure fastening without the need for additional nuts.
Shoulder Bolts
Shoulder bolts feature a smooth, unthreaded shoulder that provides a pivot point for rotating parts. This makes them ideal for mechanical applications where movement is required, such as in hinges or pivot points.
Lag Bolts
Lag bolts, or lag screws, are heavy-duty fasteners designed for wood applications. They have a thick shaft and coarse threads, making them ideal for securing heavy timber structures or decking. Their robustness is essential for outdoor and structural applications.
