A bolt that has got threaded on both of the ends with approximately equal length of the thread is termed as Double End Bolt. These bolts are having shank of standard diameter. Generally, these bolts are used for high strength bolting. It has got threads on both the ends and screw can be fastened into either of the ends, so it is said to be as a double ended bolt screw. A rod that has got snap on its both ends is said to be a double ended bolt snap. This double ended bolt snap are primarily used as a hook for diving or scuba diving as these are very good at taking loads. These double ended when made up of stainless steel are also durable and resistant to rust and dust. So Double ended bolt snap stainless steel is a better option.
Double End Threaded Stud Screw Bolt are kind of fastener that has approximate or mostly equal length of thread on its both ends. The basic application of this is in fasting and giving high strength to the structure.
These double ended bolts classify basically on the basis of diameters. A double ended bolt is stated as M4 Double ended bolt. These M4 are basically used for woodworking. The bolt that has diameter of 5mm (.1969 inches) is stated to be as M5 Double ended bolts. Double ended bolts that has diameter of 10mm are treated as one of the most heavy duty bolts. These are used for longer penetration and better fastening. These are said as M10 double ended bolt.
Some double ended bolts are not threaded and some are threaded. Bolts those are threaded on both of its ends are also classified on the basis of number of threads it has. The higher number of thread it has is higher the penetration and lock-in capacity will be there of that particular bolt. One should keep the number of threads while purchasing a double end threaded bolt.
