High performance, corrosion-resistant 316 strong marine grade stainless steel is used to make these hex head nuts and bolts, also known as setscrews, full thread stainless steel bolts. Ideal for internal and external bolting where thread lengths cannot be determined and maximum adjustment may be required, as well as for fastening into threaded components where a full length thread, running the entire length of the bolt, is required, and for corrosion-prone applications or locations, such as coastal areas.
