Stainless Steel Shoulder Bolts
304 Stainless Steel - Knurled Head
Grade 304 Stainless Steel and 18-8 Stainless Steel are the industry standard for stainless steel fasteners. This grade of stainless steel creates a corrosion resistant finish to fasteners, allowing for installation and assembly in harsh environments. For marine applications, 304/18-8 Stainless Steel is recommended for fresh water use, and if the fastener will be in a salt water environment it is recommended to upgrade to 316 Stainless Steel.
Shoulder Bolts (also known as shoulder screws and stripper bolts) are machine screws with a shoulder between the thread of the screw and the head of the part. Once installed, the non-threaded shoulder extends out of the surface of the application site, allowing the bolts to act as dowels, shafts for moving parts, axles or guides for sliding pieces of an assembly.
