مسامير ماكينة سداسية 1/4-20 × 6 بوصة | فولاذ مطلي بالزنك | ملولبة جزئيًا (200/عبوة)

The partially threaded shank on these 1/4-20 bolts gave me just the right grip length for my metal framing project. All 200 pieces came well-organized and the zinc coating looks clean and uniform.

Used these for mounting a heavy steel bracket, and the zinc plating held up well against my wrench without any galling. The partially threaded shank gave me just the right grip length for a clean, tight fit.

The unthreaded grip section on these bolts grabbed the steel plates cleanly without any wobble, and the zinc coating hasn't chipped even after tightening them with a heavy wrench. Bag of 200 was more than enough to finish the whole frame job.
