In general these stainless bolts are suitable for general structural applications where the best resistance to corrosion and staining is needed, such as most places on boats or other marine equipment. These stainless hex screws would commonly be used in and around boat engine bays, for boat trailers, dock equipment and many other general uses in and around your boat. In addition to these hexagon-head stainless steel set-screws, we also stock other head types so please look at our other items in our set-screw category before finalising your selection. Use these hex head bolts in conjunction with our washers, penny washers and regular or locking nuts depending on your sailing or other marine application. If in any doubt please do feel free to get touch with us for assistance.
