Customer Reviews (4.6 / 5 · 5 reviews)

Harper ★★★★★

These slotted heads feel like they were cut cleanly, so my screwdriver actually bites without slipping. I used them to assemble a heavy workbench frame and the 4-inch length grabbed perfectly through thick lumber. Exactly the solid, no-frills fastener I needed for indoor shop projects.

Kevin ★★★★★

Finally, a machine screw that’s actually 4 inches long when it arrives, not a hair short. The flat head sits flush in my counterbore without any wobble, and the slotted drive bites cleanly with a standard screwdriver. Plain steel is perfect for my indoor jig since rust isn’t a concern here.

Chloe ★★★★★

Needed a few for a workbench project and these 5/16-18 x 4” slotted screws worked perfectly with a countersink bit. The plain steel finish is fine for indoor use and they threaded smoothly into my pre-drilled holes.
