براغي غطاء رأس سداسي M12-1.75 X 40mm | فولاذ فئة 8.8 عادي | ملولبة بالكامل (150 / عبوة)

Used these for a heavy-duty frame repair on a press and the fully threaded design gave me excellent grip throughout. The hex heads seated cleanly with a socket wrench, and all 150 pieces had consistent threads without any burs.

These bolts threaded smoothly into the frame holes without any binding, which saved me time on a big project. The hex head held the socket tightly even under heavy torque from my impact driver. Exactly the quality I expected for 8.8 steel, and the 40mm length was perfect for this assembly.

Used a few boxes of these for assembly line jigs and the full threading made all the difference for bite. The hex head drives cleanly even with a socket on a high-torque driver.
