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 hexagonal head bolt with an integrated washer-like flange under the head. The flange distributes the load evenly, reduces the need for a separate washer, and provides a secure fastening solution.
Available in SS 304 (A2) and SS 316 (A4), these bolts offer excellent strength, vibration resistance, and superior corrosion protection, making them ideal for automotive, machinery, construction, and marine applications.
