Frequently Asked Questions
Flange bolts integrate a washer into the head, which increases the load-bearing surface area, improves vibration resistance, and eliminates the need for separate washers, thereby reducing assembly time and inventory costs.
For marine environments, we recommend Dacromet coating or Hot-Dip Galvanizing for heavy-duty protection. For extreme cases, Stainless Steel 316 or exotic alloys are the ideal choices.
Yes, they are specifically engineered for this. Their locking flange geometry and friction-optimized surfaces help maintain tension even under constant dynamic loading and thermal cycling.
Beyond high-grade alloy and stainless steels, we offer exotic materials such as Titanium and Inconel for applications requiring extreme heat resistance or chemical stability.
In steel frame buildings and bridge construction, flange bolts provide a more uniform distribution of clamping force across the joint, reducing the risk of material fatigue and surface crushing.
While the flange design inherently provides superior vibration resistance, additional locking compounds can still be used for ultra-critical aerospace or engine components depending on the engineering specifications.
