Door lock bolts have a history as a one-way type of security measure used to keep people out of a house, or any other home, when the lock is in working order. They are also known as chain locks, tie bolts, and padlocks. They are available in many sizes, shapes, and colors for a variety of purposes.
A standard bolt has a lock at one end and a keypad that is one way. The lock is tightened by pulling down on the keypad and if there is no way to get it undone then the bolt is in place and the key is unable to operate. That's when someone tries to get into the house or apartment by breaking in, which defeats the purpose of having a bolt in the first place.
For many years, bolt locks were made out of steel but today's steel and aluminum locks are made from an alloy called Chromium Vanadium. This material provides better strength than steel but is less expensive to manufacture. It is a corrosion resistant material and will last well into the future.
Brackets are used to hold the bolts in place. There are different kinds of brackets, such as tension or clevis, cutouts or tabs, and hole pegs. The grooves and slots can be made smooth so that they do not get dirty or eroded but also will not allow the bolt to move from one position to another, which makes them more secure.
Nowadays, steel door lock bolts come in three types, staggered, load pinched, and interlock bars. All three are now available in many different shapes, colors, and sizes. Staggered is the traditional style and allows two-way operation. Load pinched allows a greater amount of movement for a tighter lock.
Clevis locks on the other hand can come in any number of shapes, including trapezoid, octagon, and quadrilateral. The list continues with interlock bars and pegs. They can also be made from different materials, which could include cast iron, aluminum, steel, and glass.
Today, there are many different types of door lock bolts. They are made to fit standard bolt patterns but these variations are usually temporary. Manufacturers often offer a lifetime warranty on the products they sell so you don't have to worry about buying a cheap bolt when the lock bolt you want isn't available.
When buying a bolt for your home, make sure that it is one of the types listed above. Then get the best one for your application. Make sure that it fits snugly against the bolt post or a real good measure of the dimension that the bolt would need to fit into.
Another thing to keep in mind is that bolts are one way locks and that means that they can only be opened one way and that way is locked open. So, it is crucial that the bolt you buy has a keypad that is one way so that it is difficult to open without unlocking. Of course, your key will allow you to open it a certain way, but you should be able to undo the bolt and make a new one with one side that is facing out or in. This is important because there can be a danger that someone may try to use the bolt again to get into the house.
When buying bolts make sure that the locking mechanism has a key that is strong enough to allow it to be used in an emergency. You might not have a key of your own, but have you ever considered paying someone to make one for you? If so, that's probably a good idea, because there are many places that offer this service.
Bolts are made to use with a lock that has a keypad that is one way, and that keyway must be strong enough to allow the bolt to be operated with both ends open. Once the bolt is properly secured, that keyway will be unlocked again so that you can get in and out of the house. with ease.
