Customer Reviews (4.8 / 5 · 5 reviews)

Violet ★★★★★

Needed a heavy-duty bolt for a press fixture and these 12.9 grade screws handled the torque without any sign of stripping. The black oxide finish looks clean and seems like it will resist oil stains well.

Timothy ★★★★★

Used these for a tooling fixture in our shop, and the partially threaded design made assembly much cleaner. The black oxide finish held up well against minor coolant splashes during use.

Richard K. ★★★★★

Put these on a custom jig for a milling fixture, and the 12.9 grade alloy steel feels rock solid under torque. Torqued them to spec without any stripping or galling, which is exactly what I needed for repetitive assembly work.
