Customer Reviews (5.0 / 5 · 5 reviews)

Penelope ★★★★★

The shoulder on these is ground so smooth they slide perfectly into my bearing housings without any binding. Exactly what I needed for a custom jig pivot point.

Amelia P. ★★★★★

Needed some precise axles for a small machine build and these stainless steel shoulder screws fit the bill perfectly. The hex socket drive made installation quick with an Allen key, and the 3/8" shoulder gives a smooth, consistent bearing surface. A bit pricey per screw, but the quality is worth it

Henry M. ★★★★★

The shoulder on these screws is machined dead-on, so my axle spins without any wobble or binding. The 18/8 steel finish looks clean and should hold up fine against corrosion in my shop.
