These pins are exactly the right hardness for aligning steel components without bending. The consistent diameter made setting up my milling jig much easier than with cheaper hardware. A solid value for the quantity you get.

I’ve used a lot of dowel pins for jig work, and these alloy steel ones hold their tolerance even after repeated assembly and disassembly. Having a full pack of 100 means I didn’t have to stock up again for months, which is a real time-saver on the shop floor.

The alignment on these pins is spot-on—no wobble or play when fitting parts together. The alloy steel feels dense and precisely machined, which gave me confidence during assembly. Exactly what I needed for mounting a jig.
