Description
Product Overview
The Z QINGZHENG 7/16 Inch Steel Ball set delivers a comprehensive collection of 600 precision‑engineered stainless steel spheres, each measuring exactly 11.1125 mm (7/16 inch). Crafted from high‑grade carbon steel AISI 1015 and finished to a polished stainless steel surface, these balls provide exceptional hardness, corrosion resistance, and dimensional stability. The tight tolerance of each sphere ensures uniform weight distribution, which is critical for applications that demand consistent rotational dynamics, such as airsoft BBs, miniature bearings, and precision machining fixtures. With a total package weight of 7.41 lb and compact dimensions of 0.44 in per ball, the set balances ease of handling with robust performance. The product is packaged in a sturdy box measuring 6.06 × 4.57 × 3.54 in, protecting the spheres from contamination and mechanical damage during shipping and storage.
