Hex Bolts

Reliable Hex Bolts Supplier for Industrial Applications Grade One Fasteners is a trusted Hex Bolts Manufacturer in India, supplying high-quality hex bolts for industrial, engineering, construction, oil and gas, petrochemical, power generation and infrastructure applications. Our hex bolts are manufactured and supplied in different sizes, materials, grades, thread types and surface finishes according to customer requirements. Hex bolts are among the most commonly used industrial fasteners because of their strong hexagonal head design and reliable clamping performance. They are used to join, assemble and secure machinery, structural components, flanges, equipment and various industrial systems. We supply stainless steel hex bolts, carbon steel hex bolts, alloy steel hex bolts and special alloy hex bolts for a wide range of applications. Depending on project requirements, hex bolts can be supplied in standard sizes or manufactured according to drawings and technical specifications. What Are Hex Bolts? Hex bolts are externally threaded fasteners with a six-sided hexagonal head. The hex head allows the bolt to be tightened or loosened using a wrench, spanner or socket. A typical hex bolt consists of: Hex bolts are generally used together with nuts and washers to create secure mechanical joints. The correct material, grade, size and coating are selected based on factors such as load, temperature, pressure, corrosion exposure and application environment. Hex Bolts Specifications Specification Available Options Product Hex Bolts Head Type Hexagonal Head Size Range Standard and customized sizes Diameter As per application requirement Length Standard and customized lengths Thread Type Metric, UNC, UNF, BSW, BSF and other thread forms Thread Configuration Full Thread / Partial Thread Manufacturing Forged / Machined as per requirement Standards DIN, ISO, ASTM, ASME, BS and customer specifications Material Stainless Steel, Carbon Steel, Alloy Steel and Special Alloys Finish Plain, Black, Zinc Plated, Hot Dip Galvanized, PTFE Coated and more Customization Available as per drawing and technical requirement Types of Hex Bolts Different types of hex bolts are supplied depending on their thread configuration, material and application requirements. Fully Threaded Hex Bolts Fully threaded hex bolts have threads running throughout the usable length of the bolt. These bolts are suitable for applications where maximum thread engagement is required. Partially Threaded Hex Bolts Partially threaded hex bolts have a smooth shank section between the head and threaded portion. They are commonly used in structural and engineering applications where shear strength and alignment are important. Stainless Steel Hex Bolts Stainless steel hex bolts are widely used where corrosion resistance is required. They are suitable for marine, chemical, food processing, pharmaceutical and industrial applications. Carbon Steel Hex Bolts Carbon steel hex bolts are commonly used for general industrial and structural applications. Material grade and protective coating can be selected according to the required strength and environmental conditions. Alloy Steel Hex Bolts Alloy steel hex bolts are used in demanding applications requiring higher mechanical strength and performance. High Strength Hex Bolts High-strength hex bolts are used in heavy-duty industrial and structural applications where the joint is subjected to high loads.
