Zinc plated through bolts have a chamfered head to prevent damage to the thread during installation, and come with a special expansion clip to aid rapid installation. Our through bolts are an extremely versatile fixing for use in a wide range of anchoring applications into concrete.
NOTE: If no torque wrench is available, tighten the nut 3 to 4 full turns from finger tight.
