Types of 9/16 Bolts
Hex Bolts
Hex bolts are perhaps the most common type of bolt used in various industries. Their six-sided heads enable easy gripping with tools, making them ideal for construction and machinery assembly. Available in various grades, including Grade 2, Grade 5, and Grade 8, these bolts can be sourced from suppliers such as www.mcmaster.com and www.grainger.com.
Socket Head Bolts
Socket head bolts, characterized by their internal hex drive, offer greater torque and are more compact, making them suitable for tight spaces. They are often used in mechanical applications where a strong connection is essential. You can find a variety of socket head bolts at www.allensfasteners.com.
Carriage Bolts
Carriage bolts are designed with a rounded head and a square neck, which prevents the bolt from rotating during installation. These bolts are particularly useful in woodworking and can be found at retailers like boltdepot.com. They are ideal for securing metal to wood or for use in applications that require a smooth finish.
U-Bolts
U-bolts are shaped like the letter “U” and are primarily used to support pipes or rods. They can be found in plumbing and electrical applications, where they help secure piping systems. U-bolts are available at specialized suppliers such as uboltstore.com.
Lag Bolts
Lag bolts, or lag screws, are heavy-duty fasteners designed for wood. They have a large diameter and coarse threads, which provide strong holding power in wooden structures. These can often be sourced from retailers like www.tractorsupply.com or www.lowes.com.
