Customer Reviews (5.0 / 5 · 5 reviews)

David Z. ★★★★★

These bolts fit perfectly in my mill's arbor, and the zinc coating looks like it'll hold up well in the shop. The grade 8 strength gives me confidence for heavy clamping loads.

Scarlett ★★★★★

Used a dozen of these to repair the frame on my press, and the zinc plating held up nicely against the shop grime. The partial threading made aligning with the nut much easier than fully threaded bolts I've used before.

Jason T. ★★★★★

The hex heads on these bolts gripped my socket perfectly without any rounding, and the zinc plating looks clean and even across all 150 pieces. Used them to rebuild a rotary table mount, and the partially threaded design gave me just the right amount of clamping force. Solid fasteners for the price.
