Stainless Steel Flange Bolts

Stainless Steel Flange Bolts are hexagon flanged head bolts, serrated under the bolt head. To increase the clamping area without damaging the workpiece, we also produce the stainless steel flanged bolts without serration.

Stainless Steel Flange Bolts With Nuts

SS flange bolts are installed with stainless steel flange nuts, for different work objects, ss bolts with serration are used in conjunction with ss nuts with serration. if the requirements of the protection of the surface of the workpiece, it is necessary to flat plate flange bolt and flat plate flange nuts, they are all without serration.

The quantity of the serration under the flanged head is up to the manufacturer’s design and production. the normal quantity of serrations is 24. For different locking requirements, we can increase or decrease the number of serrations according to the customer requirements.

Superior Quality with Our Stainless Steel Flange Bolts

SS flange bolts flanged head design, in the production process of cold forming, than other types of stainless steel bolts, the amount of deformation is much larger, so leading to the edge of the head will produce fine cracks.

To solve the problem of cracking, the use of raw materials from approved factories is the only way for a solution. of course, for customized stainless steel flange bolts, we will order the raw material with slightly higher copper content to make the material softer without affecting its mechanical properties.

Material Excellence

Our Stainless Steel Flange Bolts are made from high-quality stainless steel, characterized by its high chromium content, ensuring exceptional corrosion resistance. The precise composition of the alloy used in our bolts guarantees not only durability but also resistance to extreme temperatures and chemical exposure.

Design and Manufacturing

Each bolt features a unique flange design, which provides a larger bearing surface, distributing the load over a wider area. This design is particularly beneficial in applications where there is a risk of loosening due to vibration. The manufacturing process adheres to strict quality standards, ensuring consistency and reliability in every bolt.

Quality Assurance

Every Stainless Steel Flange Bolt is rigorously tested for strength, durability, and corrosion resistance, ensuring they meet the highest industry standards.

Versatile Applications of Stainless Steel Flange Bolts

These bolts are ideal for securing pipelines, flanges, and machinery in industrial settings, especially in chemical, marine, and outdoor environments where corrosion resistance is crucial. Their strength and durability also make them suitable for construction and architectural applications.

We understand that different industries have unique requirements. Our team is equipped to provide custom fastener solutions, tailoring the chemical composition and mechanical properties of our SS Flange Bolts to meet specific needs. Whether it’s a non-standard size or a specialized application, we can develop a feasible production plan for your unique requirements.
