Good Value

Solid screws for the price. One of the 3/8 bolts had a slightly burred head, but the rest were perfect. Would buy again.

Perfect for Marine Use

I used these on a boat fixture. No signs of corrosion after three months of exposure. Very satisfied with the stainless quality.

Excellent Thread Quality

Used these for a custom jig build. The threads engaged smoothly without any cross-threading issues. The 304 steel holds up well in my workshop environment.

Great Assortment

Having multiple sizes in one kit saved me a trip to the hardware store. The hex sockets are deep enough for standard keys.

Precise Measurements

I caliper checked the diameters and pitches. They match the SAE specs exactly. Great for precision assembly work.
