Hex Head Flange Bolt, Black Oxide High Strength Flange Screw With Integrated Washer

Product Introduction

Hex flange bolt is an integrated fastener combining hex head and flange washer in one piece, eliminating manual gasket matching steps and greatly improving installation efficiency. Raw material is high-tensile carbon steel processed by cold forging, which maintains stable tensile and yield strength under heavy load. Black oxide surface treatment forms a dense protective layer to reduce metal friction wear and resist slight oxidation in dry indoor environments. The wide flange face disperses fastening pressure evenly on the workpiece surface, avoiding indentation or deformation of thin plates. The standard hex head matches all wrenches and electric tightening tools, suitable for automatic assembly lines.

Product Advantages

1. One-Piece Integrated Flange Washer: No extra gaskets, fast assembly, save labor cost.

2. High Strength Carbon Steel Raw Material: Strong bearing capacity, not easy to deform under heavy load.

3. Black Oxide Surface Treatment: Wear-resistant, scratch-resistant, basic anti-rust performance.

4. Large Flange Compression Surface: Uniform pressure distribution, anti-slip, anti-loosening and shock absorption.

5. Customizable Production: Custom thread diameter, total length and flange size per customer drawings.
