مسامير آلة سداسية مقاس 1/2-13 × 2-1/2 بوصة | فولاذ مطلي بالزنك | ملولبة جزئياً (100 / عبوة)

The hex heads grabbed my socket perfectly, and the zinc finish looks clean against the steel plate I'm bolting down. I was glad to see the grip length matched the 1/2" material thickness exactly.

The partially threaded shank made alignment so much easier when fastening steel brackets together. The zinc plating looks clean and uniform across all 100 bolts, which is exactly what I needed for outdoor equipment.

I needed bolts with a clean, unthreaded section for a tight assembly, and these 2.5-inch ones fit perfectly through the clearance hole. The partial threading gives just the right grip length, and the plating seems solid with no rough edges.
