Customer Reviews (4.6 / 5 · 5 reviews)

Alexander ★★★★★

The hex socket drive made installation quick with a standard Allen wrench, and the stainless steel finish looks clean against the pulleys I mounted. These screws held tight on a small gear shaft without any stripping.

John ★★★★★

Used a few of these to secure a timing gear and they seated perfectly with no wobble. The stainless steel finish looks clean and hopefully won't rust in a workshop environment.

Claire ★★★★★

The cup point bit down on my pulley shaft exactly where I needed it, and the 18-8 stainless finish hasn't shown a hint of rust after a week in a damp garage. For a hundred pieces at this price, the socket drive seats cleanly without stripping, which is all I ask from set screws.
