Customer Reviews (4.6 / 5 · 5 reviews)

Robert B. ★★★★★

Installed these on a custom fixture I’m building, and the fully threaded length gave me exactly the grip I needed. The 316 stainless feels solid and corrosion-resistant, perfect for marine-adjacent shop use. Fast shipping and clean threading.

Kevin P. ★★★★★

The hex socket drive seated perfectly on my wrench without any wobble, and the 316 stainless finish feels genuinely marine-grade. These are holding up great on my jig assembly after a full week of heavy use.

Andrew ★★★★★

Used these for a tooling fixture on my lathe and the hex socket drive made tightening a breeze. The 316 stainless feels solid and I'm glad they're fully threaded for a secure hold in hard materials.
