Introducing Pro-Bolt Tapered Allen Head Stainless Steel Bolts, precision-crafted to deliver superior strength and corrosion resistance. Manufactured from high-quality 316 Stainless Steel, these bolts boast a mirror finish, requiring no polishing at all.
The exceptional properties of 316 Stainless Steel make it an ideal material for applications where durability is paramount. This alloy's unique composition, comprising iron, nickel, molybdenum, titanium, copper, carbon, and nitrogen, creates a strong, chemically stable oxide film that provides remarkable corrosion resistance. Under most conditions, this protective film self-repairs when sufficient oxygen is present.
In low-stress applications where durability is paramount, 316 stainless steel is an excellent choice. It boasts good oxidation resistance up to 870°C in intermittent service and 925°C in continuous service. However, it's recommended to avoid continuous use at temperatures between 425°C and 860°C.
When using these bolts, please refer to the torque values specified by your equipment manufacturer. For general fasteners, follow the listed torque values. It's crucial to apply antiseize or copper-based paste to the threads to prevent galling (the friction that causes two stainless steel components to bond together). If threadlock is used, a medium-grade paste is recommended.
For your convenience, we've included a guide for thread diameter and torque values:
The Allen Head Bolt length measurements are taken from below the head, and the number in brackets represents the thread length.
Please note that these bolts are sold individually.
