Foundation Bolt

REQUEST CALLBACK

Foundation Bolt
Approx. Rs 200 / Kilogram
Get Best Quote

An anchor bolt is used to attach objects or structures to concrete. There are many types of anchor bolts, consisting of designs that are mostly proprietary to the manufacturing companies. All consist of a threaded end, to which a nut and washer can be attached for the external load. Anchor bolts are extensively used on all types of projects, from standard buildings to dams and nuclear power plants. They can also be used to firmly affix embed plates to a concrete foundation when used with a structural steel element.

The simplest anchor bolt is a cast-in-place anchor. As seen in the figure, most designs consist of a standard bolt with a hexagonal head, which is cast in the wet concrete before it sets. There are other designs, some consisting of a bent bolt with a hook on the end, or some other sort of bending. Cast-in-place anchor bolts are the strongest type of fastener, but the casting is difficult, and they are usually only used for heavy machines mounted on poured concrete floors. Another use of this anchor bolt is to connect the concrete foundation of a building to its wall. With this, the building is more resistant to earthquakes. Currently there are several devices to assist in holding and in placing anchor bolt to set in the concrete. These devices are mostly made from composite plastic.

Once the concrete has been poured and set, the only other types of bolts that can be used are mechanical and epoxy bolts. Epoxy bolts are the strongest, but can be very tricky to install, since the epoxy has to be mixed to exact specifications, the hole must be very clean, and the set time has to be watched. As well, there must be a rigorous testing program. In Boston's Big Dig project, these procedures were not well carried out, which resulted in a large concrete slab crushing a motorist.

A concrete screw is another way of attaching things to concrete that has already been poured and set.

U Bolts

U Bolts
Approx. Rs 200 / Kilogram

A U-bolt is a bolt in the shape of the letter U with screw threads on both ends.

U-bolts have primarily been used to support pipework, pipes through which fluids and gasses pass. As such, U-bolts were measured using pipe-work engineering speak. A U-bolt would be described by the size of pipe it was supporting.

For example, a 40 Nominal Bore U-bolt would be asked for by pipe work engineers, and only they would know what that meant. In reality, the 40 nominal bore part bears little resemblance to the size and dimensions of the U-bolt.

The nominal bore of a pipe is actually a measurement of the inside diameter of the pipe. Engineers are interested in this because they design a pipe by the amount of fluid / gas it can transport.

As U-bolts are now being used by a much wider audience to clamp any kind of tubing / round bar, then a more convenient measurement system needs to be used.

Four elements uniquely define any U-bolt:

  1. Material type (for example: bright zinc-plated mild steel)
  2. Thread dimensions (for example: M12 * 50 mm)
  3. Inside diameter (for example: 50 mm - the distance between the legs)
  4. Inside height (for example: 120 mm)

ASTM A 193 B7
APPLICATIONS/ ADVANTAGESB7  are best suited for use in temperatures between 300° - 400° C.
MATERIALBolts shall be made from a grade B7 alloy which conforms to the following chemical composition requirements--
Carbon: 0.37-0.49%; Manganese: 0.65-1.10%; Phosphorus: 0.035% max; Sulfur: 0.040% max; Silicon: 0.15-0.35% ; Chromium: 0.75-1.20% ;Molybdenum: 0.15-0.25%
HEAT TREATMENTImmediately after rolling or forging, the studs are cooled to a temperature below the cooling transformation stage. Parts are then hardened by heating to a temperature of 870°C and oil quenched then it is reheated to a minimum tempering temperature of 593°C and cooled in still air.
HARDNESS Rockwell C35 maximum
YIELD STRENGTHStuds 2.5” in diameter and smaller: 105,000 psi. minimum
TENSILE STRENGTHStuds 2.5” in diameter and smaller: 125,000 psi. minimum
ELONGATION IN 4D16% minimum
REDUCTION OF AREA50% minimum
PLATINGStuds are typically provided plain without a secondary finish or as per requirement
