صواميل قفل 1/4-20 | فولاذ بزنك ثلاثي التكافؤ (5000 / عبوة)

Honestly, I wasn't expecting much from a box of jam nuts, but the trivalent zinc coating is flawless and uniform across every single piece. This 5000-count pack is a serious bulk buy, and the steel feels dense and solid. Fully stocked for years of projects now.

The trivalent zinc finish on these jam nuts looks clean and seems like it’ll resist rust well in my outdoor projects. I used a whole bag on a shelving build and every nut threaded smoothly onto the bolts without any jamming.

The hex head on these jam nuts grabs a wrench perfectly, and the zinc finish looks clean and uniform across all 5000 pieces. I've already used a few hundred on a trailer rebuild and they thread onto 1/4"-20 studs without any binding.
