TYPES OF BOLT
- Anchor bolt
- Carriage bolt
- Eye bolt
- Hanger bolt
- Hex bolt
- Square head bolt
- U-bolt
- Lag bolt
1. Anchor Bolt: ( Types of Bolts )
Bolt with threaded portion at one end and a non threaded l shaped on to the other end of the anchor bolt. Generally found with washer & nut (rust resistant Property).
Application: setting the light poles, fastening the equipment to the concrete base.

Application: wooden goods fastening with metals.
3. Eye bolt: ( Types of Bolts )
Eye bolts are fasteners with rod shaped (with threads) on one end and forming the loop o the other end.
Application: used for high load and lifting application (heavy service).
4. Hanger Bolt: ( Types of Bolts )
Hanger bolts produced with no head on the upper end of the bolt. Both ends of the hanger bolts are threaded. One end of the bolts having the shape of wooden screw.
Application: In overhead (elevated) application, fastening with wooden application & rod application.
