Customer Reviews (4.8 / 5 · 5 reviews)

Ava R. ★★★★★

The low head profile on these is a lifesaver for tight clearance spots on my jig setup — they sit flush where standard caps won’t. Threads cut clean into the alloy steel without binding, and 200 pieces means I’m set for a long while. Solid purchase for the price.

Michael Y. ★★★★★

Needed a batch of low-profile fasteners for a jig build, and these 40mm screws fit perfectly in tight spots where a standard cap head wouldn't clear. The partially threaded shank gives just enough grip without wasting thread engagement. Came well packed and the hex drive hasn't stripped on me yet.

Sofia ★★★★★

The partially threaded design made these perfect for clamping my jig without bottoming out. All 200 screws were consistent in thread quality and finish.
