Coil Bolts

How do I determine the appropriate length of a hex head coil bolt?

The length of the bolt should be such that it passes through the materials being fastened, leaving enough exposed thread for the attachment of a nut.

How to prevent hex head coil bolts from loosening over time?

To prevent loosening, use a locking mechanism such as a locking washer, lock nut or thread-locking adhesive.

What is the difference between fully threaded and partially threaded hex head coil bolts?

Fully threaded hex head coil bolts have threads that extend along the entire length of the bolt shaft. Partially threaded hex head coil bolts, on the other hand, have a section of unthreaded shaft near the head. The choice between fully threaded and partially threaded bolts depends on the specific application and the desired level of thread engagement.

How to use these bolts?

• Ensure that the materials (to fasten together) are clean, free of debris and properly aligned.
• Insert the threaded shaft of the bolt through the aligned holes in the objects you want to fasten. The length of the bolt should be sufficient to pass through the materials and allow for the attachment of a nut on the other end.
• Position the circular flange of the bolt against the surface of the material to be fastened.
• Place a washer (if not already pre-assembled) and then thread a nut onto the exposed end of the bolt.
• Use a wrench or socket to tighten the nut, applying rotational force to draw the bolt further into the material and create a secure connection.
• Continue tightening the nut until the desired level of tightness is achieved.
• After tightening, inspect the fastened objects to ensure they are securely held together.

Do these bolts follow the Metric or Imperial system?

These coil bolts follow the Imperial system of measurement.
