FLANGE BOLT
We offer a wide range of metal bolts and studs. What is the difference between screws and bolts? Bolts can be described as long shafts with a distinct head on one side. These are generally partially threaded. A fully threaded bolt is referred to as a screw.
FLANGE BOLT DIN-6921
📌 Overview
The Stainless Steel Flange Bolt – DIN 6921 is a high-performance fastening solution featuring an integrated washer flange beneath the hexagonal head, eliminating the need for a separate washer in many applications. The flange provides a larger bearing surface, distributes the clamping load evenly, and helps reduce the risk of surface damage and loosening under vibration.
Manufactured from SS304 (A2) and SS316 (A4) stainless steel, DIN 6921 flange bolts offer excellent corrosion resistance, high mechanical strength, and long service life, making them ideal for automotive, industrial, construction, marine, and structural applications.
