Save on shipping!

You can select smaller lengths and switch from freight to standard shipping and save!
How does selecting smaller lengths reduce shipping costs?
Reducing your order from an oversize item that requires expensive freight services to a smaller bundle makes it eligible for less expensive (and faster!) standard shipping services.

*Material tolerances will remain +/- 0.125".

Best shipping value:
Single Heat Lot Required
Why are heat lots important?
Heat lots ensure consistent metal properties, full traceability, and quality control, which are critical for precision and reliability in your projects.

By selecting "Single Heat Lot Required" option, we ensure all cut pieces are sourced from a single heat lot for consistency in material characteristics.

PRODUCT OVERVIEW

0.25" (Grade 1000) 1018 Carbon Steel balls are an economical reliable solution for anti-friction bearing applications due to their high hardness and wear resistance. 1018 Carbon Steel balls are case hardened to Rockwell C 60 therefore will have poor machinability. They are also highly responsive to magnets. This is a package of 250 Steel balls.
