BARREL NUT A/KEY 6MM X 12 STEEL N/PLATE

A barrel nut is a cylindrical internally threaded fastener used in conjunction with a bolt to create a strong, right-angle connection between two components. The threaded hole runs perpendicular to the barrel’s axis, allowing the bolt to pass through one piece and engage the nut from the side. Barrel nuts are commonly used in furniture, architectural joinery, and machinery assembly for secure, concealed joints.
