Photograph the nut shape separately
Many replacement problems come from the nut shape, not the screw thread itself. Take a front view, side view, and angled top view of the nut so the supplier can see the flange, oil hole, mounting face, and nut length.
Flange direction must match the machine mount
The same screw diameter and lead may still fail if the flange direction is different. The photo should show which side of the nut has the flange, nut direction, whether the mounting face points toward the motor side, and whether dust protection or a special boss exists.
Mounting hole positions need a square photo
Photograph mounting hole positions perpendicular to the flange face and keep all holes in frame. Hole distance, hole diameter, counterbore, or threaded hole positions should be clear. If center height can be measured, state the center height and reference surface.
Use photos with a ruler or caliper
Use photos with a ruler or caliper for hole distance, outer diameter, flange thickness, and nut length. Do not cover the hole edge or mounting face, and keep caliper readings readable so the supplier does not estimate by photo scale.
Nut photo RFQ checklist
- Front view, side view, angled top view of the nut, plus one full screw photo.
- Flange direction, mounting face direction, oil hole position, and dust protection.
- Mounting hole positions, hole distance, hole diameter, counterbore, or threaded hole details.
- Center height, nut length, flange thickness, and nut housing space in the machine.

Turn this guide into an RFQ
When the specification direction is clear, send the details below together with quantity, lead time, and packing requirements.
Include these details
- Old-part overall length, thread length, diameter, lead, and nut style.
- Full old-part photos, both end details, nut flange, and mounting-hole photos.
- Machine use, whether it is a like-for-like replacement, quantity, and lead time.

Why a Replacement Ball Screw Should Not Be Quoted Only by Overall Length
Overall length is only one dimension. Thread length, end machining, and installation positions decide whether the replacement fits.
