Anchor Bolt is a fastener used to attach objects or structures to concrete. A typical anchor bolt used for building steel structure consists of the following.

• Partially threaded rod of F1554 grade 36, 55 and 155, A449, A354 etc.
• Tack welded nut at the bottom of anchor rod or it can be a headed bolt
• Washer and nut at the top of the anchor rod. Sometimes, two nuts are used for levelling the base plate. One below the base plate and one above the base plate

Sometimes, L shaped anchor bolts are also used where there are heavy earthquake loads to be transferred to concrete foundations.

Along with anchor bolts, steel templates are also supplied in order to ensure that anchor bolts are cast in place at an exact location to match with base plate of steel columns.

Purpose of an embed plate is to transfer load from steel framing to concrete wall / foundation. Headed studs are welded on embed plates to provide shear and axial resistance. Also, nail holes are provided on embed plate to secure it in position while concrete is cast.
