براغي كتف M6 × 25 مم | رأس سوكيت | محرك سوكيت | ستانلس ستيل 18/8 (25 / عبوة)

These shoulder screws are holding up great as axle pins in my 3D printer's linear rail setup. The precision-ground shoulder made for a smooth, tight fit without any wobble.

Used a set as pivot pins for a small hinge mechanism, and the precision-ground shoulder made everything fit snug without any wobble. The hex drive seated the screws smoothly and the stainless finish cleaned up nicely.

The shoulder on these screws is machined perfectly smooth, which made them ideal for a small rotating axle I was building. I used them as bearing surfaces, and they spin with almost no friction.
