Depending on the type of project you are working on, you may come across a need for a custom bolt of screw. There are many different types of custom fasteners including micro fasteners or undersized screws and shoulder bolts.
There are also options in thread lockers. The two primary types of thread lockers are inert thread lockers and reactive thread lockers. An inert thread locker is resistant to vibration and shock, which is often essential to the finished product.
Miniature screws are exactly what their name suggests and are needed in small projects and tight spaces. They can be custom made to fit the size of the project with the correct specifications.
A custom shoulder bolt is generally made for a specialized purpose. They are seen most often in automotive and mechanical projects. What makes a shoulder bolt unique from other bolts is that the threads do not go all the way to the head. They stop a specific distance from the head leaving a smooth-sided shaft between the threads and the head of the bolt. The shaft is typically large in diameter than the threads, which creates a stop or pivot point on the bolt.
When ordering a custom shoulder bolt, you need to know the length needed, the diameter of the threaded part, the diameter or multiple diameters of the smooth shaft, and the distance needed between the head and the threads. These are all very specific specifications in order to get exactly what you need.
This level of precision is common in mechanical and automotive products, which typically have multiple moving parts, which must move succinctly at all times. These types of custom bolts are typically designed by engineers, who understand how to design what is needed based on the project.
When ordering custom fasteners, it is important to work ahead since the manufacturer needs time for the production of all custom products. These are not last minute items. Additionally with the work needed to design a custom fastener, if the need is discovered after the project has started, everything will be delayed. There is simply no way around that.
The best approach is to plan well in advance. Taking an organized and proactive approach will ensure the project is completed in a timely manner. Once the first project is complete, subsequent ones utilizing the same parts will go quicker as the mold will already be made.
