Reply To: How to undo torque bolt

#503268

Torque bolt being the rear linkage bolts sensitive to force, measured in NM. That’s what all the shops and riders around me call it, so that’s what I say. If you know a different word for it, I’d be interested in hearing it

As I use many forms of fasteners daily, I had to ask. Every bolt I have ever used has a torque rating and therefore was confused by the terminology.

There is a term known as torque to yield. That type of bolt will be immediately replaced with a standard grade 5 or 8 stud to eliminate the issue of failure. These are guaranteed to fail if not torqued to a specific value, then torqued in one or two 90° increments. These are said to not be reusable and are typically replaced.

Of the many full squish frames I have fabbed over the years, the suspension pivot bolts are pivot bolts, the rocker bolts are rocker bolts.

What ZipHead posted should get you back on track, lest the bolts were loaded with locktite or similar. That may require some heat to do the deed.

Good luck, gitter dun!
