Customer Reviews (4.4 / 5 · 5 reviews)

Eli ★★★★★

Fit perfectly into my jig fixture, and the fully threaded length gave me plenty of grip for clamping. The zinc plating seems uniform and should hold up well in my shop.

Matthew ★★★★★

Used these for a jig build and the flat head sits perfectly flush without any wobble. The hex socket drive made installation quick with no stripping issues.

Thomas ★★★★★

Picked up a pack of these for a jig I'm building, and the hex socket drive makes installation in tight spots so much easier than a standard hex head. They seat flush and feel solid with no wobble. All 400 counted out perfectly, so I'm set for a while.
