Makers Bolt black lag bolts are 100% solid 18-8 (304) Certified Stainless Steel providing premium protection against rust. Our lag screws are Black Oxidized here in the USA giving these hard to find fasteners a black coating. The coating not only provides a non-reflective look, it also provides increased corrosion and abrasion resistance. The Black Oxide is applied to military spec MIL-DTL-13924D Class 4. Unlike painted, powder coated, or zinced finishes, this finish will not chip, peel, or scratch off. These black lag bolts are perfect for exterior applications where high corrosion and rust resistance is required such as deck building or manufacturing assembly equipment. Lag screws are typically used for wood applications where a heavy-duty fastener is needed to join to pieces of wood or attach metal to wood. Pair these with our stainless-steel fasteners to distribute the load and protect the material under the head of the fasteners. Drill a pilot hole before installing the lag screws to prevent the head from breaking under torque. Our fasteners are not only made from certified 18-8 stainless steel, the specialty finish will give your project a unique touch.
