The precision-ground shoulder on these screws is perfectly smooth, making them ideal for a custom axle I built. They were exactly the right length, and the alloy steel feels really solid in my hand.

The hex socket drive seated my Allen key perfectly, and the precision-ground shoulder slid into the bearing without any wobble. Used them as pivot pins on a jig I’m building, and they’ve held up through a week of heavy use without a hint of wear.

The shoulder is dead-on the 0.75" spec I needed for a shaft pivot, and the hex drive seated perfectly without any wobble. These alloy steel screws feel dense and solid, definitely up to the job.
