Frequently Asked Questions

Q: Are mounting screws included?
A: Yes! Each 6-inch hinge comes with a set of matching 316 stainless steel screws (approx. 1.38" / 35mm length), so you can install it right out of the box.

Q: What is this 6-inch size best used for?
A: Due to its longer strap and 4.5mm thickness, the 6-inch model provides excellent leverage. It is highly recommended for heavier applications like boat engine hatches, large dock gates, barn-style doors, and heavy utility trailer ramps.

Q: Is the 4.5mm thickness standard?
A: No, most standard hinges on the market are only 2mm or 3mm thick. Our 4.5mm cast design makes this a true "Heavy Duty" class hinge.
