About Machine screw

A machine screw is a precision-engineered fastener designed for securely joining metal components or fastening parts in pre-threaded holes. Known for its uniform threading and reliable performance, it is widely used in mechanical, electrical, and industrial applications where strong and stable fastening is required.

Manufactured from high-quality materials such as stainless steel, carbon steel, or alloy steel, machine screws offer excellent strength, corrosion resistance, and long-lasting durability. They are available in a variety of head types (pan, flat, round, hex, etc.), drive types (Phillips, slotted, Allen/hex), and thread sizes, making them suitable for diverse assembly requirements.

Machine screws are designed to be used with threaded holes or nuts, ensuring tight, vibration-resistant fastening and easy installation or removal when needed.

Exceptional Durability and Strength

Featuring a galvanized, zinc-plated finish and made from high-quality mild steel, this machine screw is designed for superior corrosion resistance and robustness. Its Grade 4.8 classification and minimum tensile strength of 420 MPa ensure reliable fastening performance across various demanding environments.

Adherence to International Standards

Manufactured as per DIN 7985 specifications, each machine screw is precision-engineered for consistency in dimensions, threading, and mechanical properties. The M4 x 16 mm size caters to a spectrum of uses in both industrial and commercial settings, providing peace of mind for engineers and technicians alike.
