براغي ضبط رأس مقبس نقطة كلب نصفية 1/4-28 × 3/8 بوصة | فولاذ سبائكي (250 / عبوة)

The half dog point grabbed perfectly on my jig fixture, and the alloy steel feels tough enough for repeated adjustments. These set screws fit my 1/4-28 taps without any binding, and the hex drive held up well under high torque. Exactly what I needed for a reliable lock in tight spots on the workbenc

The hex socket drive made torquing these into a tight spot a breeze, and the half dog point seated perfectly every time. Alloy steel feels solid for the price, and the 250 count will last me a while. Exactly what I needed.

Used a few of these to secure a shaft alignment jig, and the hex socket made tightening in a cramped spot much easier than a standard set screw. The alloy steel feels sturdy enough for repeated adjustments. Only wish the package had a small quantity option.
