Brian ★★★★★

I needed longer fasteners for a jig assembly and these 155mm M6 screws fit perfectly—the hex socket drive made install in tight spots a breeze with just a standard Allen key. Definitely glad I grabbed this pack.

Victoria ★★★★★

These bolts threaded into my fixture block without any binding. The black oxide finish gives them a nice, uniform look and seems durable. Exactly the length I needed for a deep assembly.

Miles Q. ★★★★★

Needed a long bolt for a custom jig I’m building, and these 155mm lengths with partial threading handled the deep clamp loads perfectly. The black oxide finish feels durable and hasn’t flaked off during assembly.
