Harper ★★★★★

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.

Brian U. ★★★★★

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.

Evelyn ★★★★★

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.
