Specification

Precision Socket Head Shoulder Screws also as known as shoulder screws or tripper bolts, are threaded fasteners that have a cylindrical head with a hexagon socket and a precision unthreaded shoulder. Socket Head Shoulder Bolts can withstand higher transverse loads and can be used for a variety of applications. allow for the rotation of pulleys, linkages, and other moving parts in engines and mechanical applications.

How to Choose the Shoulder Bolts

Locking will inevitably occur when using Precision Socket Head Shoulder Screws because the shoulder screw themselves have good anti-corrosion properties, but when their surface is damaged, a protective film will be formed on the metal surface of the shoulder screw to prevent The screws corroded again. When stainless steel fasteners are locked, the pressure and heat generated between the teeth will make this layer of protective film lose its effect, causing blockage between the threads, and the locking phenomenon will gradually occur. So in order to prevent or reduce this phenomenon from happening, what should we do?

1. Choose the right shoulder screws. Before using custom shoulder screws, you must first confirm that the mechanical properties of the screws meet your needs, such as the tensile properties of the screws and the guaranteed load of the nuts. Also, the size of the screw should be confirmed. It is better to expose two or so teeth after tightening.
2. It is also necessary to confirm whether the thread is a go-no-go gauge and keep it clean and free of debris between the threads, because debris may cause locking.
3. Lubricate the metric shoulder bolts before use, which can prevent the screw from locking.

How to Use Shoulder Bolts

1. When installing precision socket head shoulder screws, do not screw in too much force or too fast. Use a torque wrench or socket wrench as installation tools, but an adjustable wrench or an electric wrench cannot be used. Because it is easy to lock up when using an electric wrench.
2. When tightening, not only pay attention to the speed but also pay attention to the direction of the force. The nut must be screwed perpendicular to the axis of the screw, and it should not be crooked.
3. It will be better to add a washer to cooperate with it, so as to prevent the problem of over-tightening the lock.
