David ★★★★★

The pin-in socket drive is a nice touch — it keeps the wrench from slipping off when I’m working in tight spots. Used a handful for a tooling fixture and they seated cleanly without any wobble. Solid buy for the price.

Zoe ★★★★★

Finally found the exact pin-in socket screws I needed for a custom jig, and these 18/8 stainless ones are exactly as described. The #8-18 size fits my tooling perfectly and the tamper-resistant drive is a nice bonus for security. Very happy with the quality for the price.

Jason ★★★★☆

Installed these on a precision jig and the 18/8 stainless gives great corrosion resistance for a shop environment. Only minor thing is I wish the package included a couple extra for my inevitable fumbles.
