Stainless Steel Hex Bolts for Demanding Engineering Applications
Product Overview
An Stainless Steel Hex Bolt is an externally threaded fastener with a six-sided head, designed for secure bolted connections in demanding engineering applications. Stainless steel is selected when the fastening system requires suitable strength, toughness and mechanical performance.
These hex bolts can be supplied in different grades, diameters, lengths, thread configurations and finishes. However, the correct grade and configuration should always be selected according to the required load, temperature, service environment and applicable product specification.
Materials & Grades
Stainless steel is selected for applications where the fastener requires higher mechanical performance than a general-purpose fastening material can provide. Moreover, the exact stainless steel grade should be selected according to the applicable standard and service conditions.
Common Stainless Steel Fastener Options
304 Stainless Steel
A widely used austenitic stainless steel option for general industrial applications where corrosion resistance and durability are required.
316 Stainless Steel
Selected for applications requiring enhanced corrosion resistance, particularly in environments where chloride exposure may be present.
316L Stainless Steel
A low-carbon stainless steel option used where corrosion resistance and suitable fabrication characteristics are required.
410 Stainless Steel
A martensitic stainless steel option that can provide suitable strength and hardness for selected fastening applications.
420 Stainless Steel
A martensitic stainless steel grade used for applications requiring suitable hardness and mechanical performance.
Custom Grade Requirements
Other stainless steel grades can be discussed according to approved drawings, purchase specifications and applicable standards.
Fastener Specifications
Stainless Steel Hex Bolt dimensions, grades, threads and finishes can be selected according to the project drawing or purchase specification. Therefore, the final configuration should match the required load, service temperature and applicable standard.
For reference, ASTM fastener standards cover specifications and testing considerations for many types of fasteners.
