Screws manufacturers in India

Types of Screws Available

1. Hex Screws

Hex screws are among the most widely used fasteners in industrial and structural applications. These screws have a hexagonal head that makes them easy to tighten using a wrench or socket tool. They offer a strong grip and high load-carrying capacity, making them suitable for heavy-duty applications. Because of their strength and stability, hex screws are commonly used in machines, engines, steel structures, and equipment installations.

2. Nylon Screws

Nylon screws are lightweight, non-metallic fasteners ideal for environments where insulation and corrosion resistance are important. These screws do not rust and do not react with chemicals, which makes them suitable for sensitive or corrosive conditions. Their excellent electrical insulation properties, durability, and light weight make them a popular choice for electronics, telecom devices, laboratory equipment, and chemical environments.

3. Self-Tapping Screws

Self-Tapping Screws are designed to create their own threads during installation, allowing them to be used directly in materials such as metal, wood, or plastic without pre-tapping. They provide easy and fast installation and offer a strong grip even in thin materials. Their ability to be reused and their reliable hold make them widely used in sheet metal work, household appliances, furniture manufacturing, and automotive components.

Screw Specifications

Below are common specifications followed for industrial screws:

  • Standards – DIN, ISO, ASTM, BS, JIS
  • Sizes – M2 to M36 (metric) / 3/16” to 2” (inch series)
  • Lengths – 6 mm to 200 mm
  • Thread Types – Full thread, half thread, coarse thread, fine thread
  • Head Types – Hex head, pan head, flat head, round head, countersunk
  • Drive Types – Hex, Phillips, Torx, slot drive
  • Finishes/Coatings – Zinc plated, hot dip galvanized, black oxide, nickel plated, natural nylon

These specifications help users select the right screw based on load, environment, and installation method.

Why Choosing the Right Screw Matters

Selecting the correct screw is important for safety, performance, and long-term reliability. The wrong type of screw can weaken the structure, loosen over time, or fail under stress. Factors like material grade, length, thread type, and coating make a big difference in the final result.

A qualified screw manufacturer ensures that each screw is designed for a specific purpose and tested for quality. Proper manufacturing and controlled production help deliver screws that fit accurately and perform well even in demanding conditions.

Materials and Quality Standards

Modern screws are made using stainless steel, alloy steel, carbon steel, and nylon. Stainless steel screws offer excellent corrosion resistance, while alloy and carbon steel screws provide higher mechanical strength. Nylon screws are preferred in electrical and chemical environments.

A dependable screw supplier ensures strict testing for:

  • Dimensional Accuracy – Ensures precise fitting and reliable assembly.
  • Thread Quality – Provides smooth engagement and prevents stripping during installation.
  • Tensile Strength – Supports high load-bearing and mechanical stress conditions.
  • Corrosion Resistance – Protects against rust and environmental wear in harsh settings.

This guarantees stable performance and a long service life.

Conclusion

Screws play a critical role in connecting parts, building structures, and ensuring safe and efficient operations across various industries. Choosing the right fastener is essential for achieving strength, safety, and long-term reliability. Working with a trusted Screw Supplier in India ensures access to high-quality, precision-engineered screws designed to meet specific performance needs. Whether you're involved in manufacturing, construction, or equipment assembly, investing in reliable fasteners is a key step toward ensuring durability and secure installations.
