Pin Type Anchor Bolt vs Anchor Bolt – What’s the Difference

Pin Type Anchor Bolt vs Anchor Bolts

Regarding construction and DIY projects, we all need to understand the different types of bolts available and their application. Two such bolts are the pin type anchor bolt and anchor bolt. Though both may look similar, they have some major differences. Understanding these differences is crucial to determine which type of bolt is best for your project needs. In this blog post, we will outline the difference between the two bolts pointwise, helping you to make informed decisions.

What is Pin Type Anchor Bolt?

Pin type anchor bolts are a type of heavy-duty fastener that are used to securely anchor materials into concrete or masonry surfaces. They have long steel pins or threaded rods with a thick flange head and nut at the base, which penetrate deep into the substrate to provide secure anchoring. Their size and shape varies depending on the application, but they can generally handle up to 70 kN (15,500 lbf) of pullout force.

What is Anchor Bolt?

An anchor bolt is a fastener that attaches objects or structures to concrete. It consists of a threaded end to which a nut and washer can be attached for the external load. Anchor bolts are available in various types and sizes and are used in many applications, including anchoring machines, retaining walls, handrails, decks and fences. They come in several materials, such as steel, stainless steel, galvanized steel or plastic coated varieties. Each type of anchor bolt has distinct advantages, so it should always be chosen based on the specific application needs.

Difference Between Pin Type Anchor Bolt and Anchor Bolt 

Bolt Length

The first difference between the two bolts is their length. Anchor bolts are usually longer than pin type anchor bolts. Anchor bolts are used for heavy-duty projects and can be up to 20 inches long. In contrast, pin type anchor bolts are shorter and are used for relatively lighter applications.

Material Used

Anchor bolts are generally made of steel, while pin type anchor bolts are made of stainless steel. This is because pin type anchor bolts are designed to avoid oxidation, which can result in corrosion. On the other hand, anchor bolts can be made of different steel grades, including carbon steel and stainless steel.


Anchor bolts usually come in two pieces- the anchor and the bolt. The anchor bolt is inserted in the hole and then cemented or glued before the bolt is screwed into the foundation. Pin type anchor bolts are different because they consist of a single piece. It is hammered into the concrete for tight fitting with the concrete and has a pronged end to provide added grip.


Anchor bolts are commonly used in heavy-duty applications, such as securing equipment to a concrete foundation or retaining walls. They are used in construction, such as fixing building frames, columns, walls, and railings. The pin type anchor bolts come in handy when securing suspended ceiling anchors, brackets, and fixtures.

Load-bearing Capacity

When it comes to heavy-duty applications, anchor bolts are known to have a higher load-bearing capacity than pin type anchor bolts. While pin type anchor bolts can hold up small-to-medium equipment loads, anchor bolts can hold up much heavier loads.


In conclusion, pin type anchor bolts and anchor bolts serve similar functions but differ in several aspects. To choose the right bolt for your project, consider the length, material, mechanism, intended application, and load-bearing capacity. Always consult an expert for specific requirements for your project. We hope this blog post helps inform you of the differences between the bolts and aids in your decision-making process.
