What sets it apart? The extra-thick flange boosts load-bearing capacity, distributing clamping force evenly across the workpiece to reduce stress concentration and prevent material damage. Paired with a fully closed end, it creates a tight, sealed barrier that keeps out moisture, dust, and debris – critical for protecting internal threads from corrosion and ensuring long-term functionality, even in harsh outdoor or wet conditions.
Crafted from premium stainless steel (available in 304/316 grades), it boasts exceptional rust resistance, chemical durability, and temperature tolerance, making it ideal for automotive components, marine equipment, construction machinery, electrical enclosures, and other applications requiring longevity in challenging settings.he extra-thick flange boosts load-bearing capacity, distributing clamping force evenly across the workpiece to reduce stress concentration and prevent material damage.
