Thomas ★★★★★

The hex head is a perfect fit for my socket set, and the 316 stainless steel feels incredibly solid compared to the cheaper hardware I've used before. These M6-1 x 40mm screws worked exactly as needed for a machinery assembly project I've been putting off.

Michael A. ★★★★★

Used these to replace some rusted bolts on a trailer gate, and the 316 stainless is holding up perfectly after weeks of rain. The hex head sat flush in my socket wrench without stripping, which was my main worry with cheaper fasteners. For a 200-pack, the quality feels solid and the partial threadin

Carter S. ★★★★★

Finally found M6 cap screws that don't strip with my hex wrench. The 316 stainless feels heavier and more corrosion-resistant than the cheaper ones I’ve used. Already used half the pack for a machinery guard, and they seat perfectly.
