3/8-16 x 3" Flache Spitze Innensechskant-Gewindestiftschrauben | Legierter Stahl (100/St.)

I needed something longer than standard set screws for a jig setup, and the 3-inch length on these alloy steel ones worked perfectly in my threaded fixture. The hex socket drive handled the high-torque adjustment without stripping.

The flat point on these set screws grips the shaft firmly without marring it—exactly what I needed for a precise machine alignment. They threaded smoothly into the tapped hole and the hex socket held up fine under moderate torque. Good value for a bulk pack of this size.

I needed something with a hex socket for a confined spot, and these 3/8-16 x 3" screws fit the bill perfectly. The alloy steel feels sturdy, though the packaging was a bit tricky to open without spilling them.
