Slotted Round Head Bolt

What is a bolt?

A slotted round head bolt is a type of machine screw that features a round head with a single slot on top. This slot allows the bolt to be tightened or loosened with a flat-blade screwdriver or other similar tools, making it a versatile and easy-to-use fastener.

Material

The most common material used for slotted round head bolts is stainless steel. Stainless steel is an alloy of steel that contains chromium, which makes it highly resistant to rust and corrosion. This makes it ideal for use in applications that require a high degree of corrosion resistance, such as marine and outdoor applications.

Stainless steel slotted round head bolts come in various grades, including 18-8, 304, and 316. 18-8 stainless steel contains 18% chromium and 8% nickel, while 304 stainless steel contains 18% chromium and 8% nickel, with the addition of 2% manganese. 316 stainless steel, on the other hand, contains 16% chromium, 10% nickel, and 2% molybdenum. The addition of molybdenum makes 316 stainless steel more resistant to corrosion in harsh environments, such as those with high levels of saltwater or chlorine.

Slotting Design

The slotting design of round head bolts is unique and allows them to be tightened or loosened with a flat-blade screwdriver or other similar tools. The slot is typically cut into the top of the bolt head and runs perpendicular to the axis of the bolt. This design allows the bolt to be tightened or loosened quickly and easily, even in tight spaces where other tools cannot reach.

The slotting design of slotted round head bolts also makes them ideal for use in applications where the bolt needs to be adjusted or tightened frequently. For example, in machinery or equipment that requires regular maintenance or repairs.

Thread

The thread of a slotted round head bolt is another important aspect to consider when choosing the right bolt for your needs. The thread determines how tightly the bolt will fit into the corresponding hole or nut, and how much force is required to tighten or loosen the bolt.

The thread of bolts can be either coarse or fine. Coarse threads have fewer threads per inch and are typically used in applications that require a faster installation time, while fine threads have more threads per inch and are used in applications that require a higher degree of precision and strength.

Additionally, they are widely recognized and have a traditional appearance, making them a popular choice in certain applications.

Q: What is the difference between a round head and a pan head bolt?

A: The main difference between a round head bolt and a pan head bolt is the shape of their heads. A round head bolt has a flat bearing surface and a rounded top, while a pan head bolt has a flat bearing surface and a flat top that is wider than the shank. Pan head bolts are commonly used in situations where a low-profile head is required.

Q: How do you remove a slotted bolt?

A: To remove a slotted round head bolt, you will need a flat-head screwdriver that fits into the slot in the bolt's head. Place the screwdriver into the slot and turn it counterclockwise to loosen the bolt. If the bolt is stuck, you may need to apply some penetrating oil or heat to loosen it before attempting to remove it. Alternatively, you can use a pair of pliers to grip the shank of the bolt while turning the head with a screwdriver.
