Connect these internally threaded shafts directly to threaded components, or use a fastener to secure. Thread these shafts into a tapped hole to support idler sprockets and pulleys in tensioning applications.

What can be threaded into a mixer shaft?

Attach threaded accessories, such as mixer propellers and fan blades, to the end of these shafts.

Do you need a hex nut for a threaded shaft?

Threaded Linear Motion Shafts Mount these externally threaded shafts into tapped holes rather than using a shaft support, or attach a hex nut, shaft collar, or other threaded accessory. Tapped Linear Motion Shafts Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed.

How do you fix a drive shaft on a Model T?

What is an example of a damaged thread?

Example 1 – Damaged threads on a the end of a tie-rod (such a hammer blow rolled the edge and the castle nut won’t start); this is a safe repair item. The threads on this steering bar have rolled edges, this can be repaired without affecting the performance.

When to replace damaged threads on a car?

If it is a high-load or critical part (steering, suspension, drivetrain), consider replacing the item over repair. Example 1 – Damaged threads on a the end of a tie-rod (such a hammer blow rolled the edge and the castle nut won’t start); this is a safe repair item.
