The substantial 180mm length is ideal for penetrating and joining thick double timbers, such as twin 75mm or 3-inch joists, leaving plenty of room for heavy-duty washers and the nut.
Featuring a robust 12mm thread diameter, these bolts provide massive tensile and shear strength, guaranteeing stability for heavy roofing, framing, and load-bearing structures.
Coated in a durable BZP finish that resists oxidation and rust, providing excellent longevity for indoor structural applications and sheltered outdoor projects.
Comes complete with 10 perfectly matched M12 nuts. This convenient project-pack size gives you enough hardware to tackle a substantial framing or landscaping job without running short.
This bolt has a square shoulder under a rounded head (Mushroom Head) which resists turning when the nut is tightened or removed. The bolt is driven into a hole the same size as the shank and then hammered the rest of the way, where the square shoulder locks firmly into place.
