Richard B. ★★★★★

The partial threading on these 3/4-10s grabbed just right when I torqued them down for a heavy equipment frame—solid bite without any galling. Pack of 35 was more than enough for the job, and the plain A307 finish is exactly what I expect from domestic steel.

Steven C. ★★★★★

These bolts threaded in smooth and clean, the hex heads held up well to torque without stripping. They're a solid choice for mounting heavy equipment in my shop, and the 35-count package gave me enough extras for the next job.

Abigail ★★★★★

The partial threading on these hex cap screws makes them perfect for the mounting flange I was working on — they grab deep without bottoming out. Great grip and clean threads right out of the package.
