Product Name

Hex Head Flange Bolt DIN 6921

Details Information

Introduction

Flanged bolts, also known as frame bolts, have a wide circular flange at the base of the bolt head. 

Compliant with both GB5787 (Chinese standard) and DIN 6921 (German standard), these stainless steel hex head flange bolts integrate high performance and universal compatibility, designed for reliable fastening across industrial, mechanical, automotive, and construction scenarios. Crafted from premium stainless steel (A2/304, A4/316 optional), they deliver exceptional corrosion resistance, rust protection, and mechanical strength—ideal for indoor, outdoor, and mild corrosive environments such as coastal areas, humid workshops, or chemical-exposed equipment.

 Features 

This flange provides a larger bearing surface, which distributes the load over a wider area and reduces the risk of the bolt head damaging the material it is secured to. 

 Applications 

Flanged bolts are commonly used in automotive and construction applications, where the wide bearing surface is essential for strength and stability.
