قواعد موازية رقيقة، 3" طول، 4 أزواج (أساسيات)

I needed a precise setup for a drilling job on my mill, and the 3" length let me space out a thin workpiece perfectly. The alloy steel finish feels solid and hasn't shown any wear after several uses. Good value for a set of four common sizes.

These parallels are dead-nuts accurate right out of the box — I checked each pair with a micrometer and they're all within a tenth. The 3-inch length is perfect for holding small workpieces in the vise for drilling and light milling.

Machined my first steel block on the mill today and these parallels slid right into the vise without any binding. The 3" length is perfect for holding small parts securely.
