M12 x 200mm Bright Zinc Plated Cup Square Hex Bolt

Summary

The M12 x 200mm Cup Square Hex Bolt is a BZP (bright zinc plated) coach bolt designed for heavy-duty timber and structural connections. Its distinctive domed cup head and square shank section beneath grip the timber and resist rotation during tightening, making it ideal for joinery, fencing, and general construction applications. The bright zinc plating provides corrosion resistance suitable for indoor and sheltered outdoor use.
