Tensile Strength of Nuts and Bolts – What You Need to Know?

 

Introduction

The tensile strength of nuts and bolts is a crucial factor in ensuring the safety and durability of industrial, construction, and automotive applications. Understanding tensile strength helps buyers choose the right fasteners for high-load environments. As a leading nut and bolt supplier in Delhi, Udhhyog provides expert insights into tensile strength and its significance.

What is Tensile Strength?

  • Tensile strength is the maximum stress a bolt or nut can withstand before breaking or failing.

  • It is measured in megapascals (MPa) or Newton per square millimeter (N/mm²).

  • Essential for applications that require high-load resistance and structural integrity.

Tensile Strength Grades for Nuts & Bolts

1. Mild Steel (MS) Bolts – Grade 4.6 & 5.6

  • Tensile Strength: 400-600 MPa.

  • Best For: General-purpose applications, furniture, and light construction.

2. High-Tensile Bolts – Grade 8.8, 10.9 & 12.9

  • Tensile Strength: 800-1200 MPa.

  • Best For: Heavy-duty machinery, industrial structures, and automotive use.

3. Stainless Steel (SS) Bolts – A2-70 & A4-80

  • Tensile Strength: 700-800 MPa.

  • Best For: Corrosion-resistant applications, marine, and chemical industries.

4. Structural Bolts – ASTM A325 & A490

  • Tensile Strength: 900-1200 MPa.

  • Best For: Bridges, steel structures, and high-load construction projects.

How to Choose the Right Bolt Strength?

  • Assess Load Requirements – Higher loads require high-tensile bolts.

  • Consider Environmental Factors – Use stainless steel bolts for corrosion-prone areas.

  • Verify Industry Standards – Ensure compliance with ISO, ASTM, and BIS certifications.

  • Check Application Needs – Structural projects require specialized high-strength fasteners.
