Threaded Rods & Anchor Bolts

Anchor bolts are used to secure structural elements to concrete. Anchor bolts are commonly used in our industry to secure steel to concrete. One end is embedded in concrete, while the other is threaded to attach structural support. Anchor bolts are classified into four types: L-shaped, double end rods with plate, headed, and swedge. Each type has its own set of applications, sizes, and benefits. Let’s take a look at each type of anchor bolt and how they’re used in structural applications on a daily basis.

Process For Manufacturing Threaded Rod

The making of top quality threaded rods in India is a long process mainly containing 5 main steps. Every top threaded rod manufacturer in India ensures strict follow up of all these steps to manufacture the best quality threaded rod in India. Let’s look at the process in a nutshell to know the complete steps for manufacturing quality threaded roads with Hydraulic Thread Machines:
L-Shaped Anchor Bolts
Light poles, sign structures, heavy equipment, and tooling all use L-shaped anchor bolts. Birmingham Fastener distributes L-shaped bolts in the following standards: A307, F1554-36, F1554-55, F1554-105, A193 B7, 304 Stainless, 316 Stainless, and any grade the customer may require.

Double End Rods with Plate
These anchors are double-ended rods with a plate washer attached to one end. The plate can be welded to the anchor bolt itself or tack welded to a nut embedded in concrete. Plate bolts are primarily used in the construction of columns for buildings, highway signs, and other purposes. We distribute straight with plate bolts in 3/8″-4″ diameter and any length required in the following standards: A307, F1554-36, F1554-55, F1554-105, A193 B7, 304 Stainless, 316 Stainless, and any grade the customer may require.

Headed Anchor Bolts
Headed anchor bolts, unlike most anchor bolts, have a forged head on the unthreaded end. It usually has a hex, heavy hex, or square head. The head is embedded in concrete to secure a variety of structures such as structural columns, bridge railings, and light poles. We distribute straight with headed anchor bolts in 1/2″-2″ diameter and any length required in the following standards: A307, F1554-36, F1554-55, F1554-105, A193 B7, 304 Stainless, 316 Stainless, and any grade the customer may require.

Swedge Bolts
Swedge bolts are made of round bar steel that has one end threaded and the other “swedged.” The term “swedged” refers to one end having multiple indentions to allow concrete to flow into them. Swedge bolts, which are used to connect girders and piers, are entirely made in the United States. The majority of swedge bolts are hot-dipped galvanized and range in diameter from 5/8″ to 4″. Other materials, such as stainless steel, are also available.
