مسامير تثبيت 5/16 × 2-5/8 بوصة | مقساة | فولاذ سبائكي (100 / عبوة)

Needed these to replace worn pins on a precision fixture, and the hardened alloy steel feels substantially tougher than the standard ones I used before. Each pin measured exactly 5/16" diameter with consistent length, so no time wasted sorting bad ones.

Slid right into place on my jig with zero binding—the alloy steel is definitely harder than the cheap zinc ones I've tried. These pins are holding a cabinet alignment perfectly after a week of use.

Used these to pin some heavy framing together, and the 5/16" diameter gave a really solid, tight fit. The hardened steel held up without bending when I hammered them in. A hundred in the pack was just right for the project.
