Customer Reviews (4.8 / 5 · 5 reviews)

Aurora ★★★★★

Used a few to replace a stripped bolt on a milling machine jig, and the partially threaded design made alignment much easier. The 18/8 stainless has held up well under moderate torque without any galling.

Carter ★★★★★

I needed bolts that could handle constant torque on a milling fixture, and these haven't stripped or corroded even after months of coolant exposure. The hex socket drive fits my Allen keys perfectly, no wobble.

Grace ★★★★★

Used a few of these to repair a jig at the shop and they threaded in clean without any galling. The partial thread on the 1-3/4" length gave just the right grip for a steel bracket. Solid American-made feel, no wobble once torqued down.
