Brass Machine Screws

Machine-Screws

We are one of the leading manufacturers and exporters of Brass Machine Screws from India. We have been supplying precision‑engineered Brass Machine Screws to the global market for over 29 years. Located in Jamnagar, Gujarat, our facility produces both cold‑forged and bar‑turned Brass fasteners in metric and imperial sizes. From standard DIN head styles to fully custom, non‑standard designs, we deliver countersunk, Philips, Pozidrive, truss, raised pan, round, cheese, socket‑head screws—and matching nuts, studs, standoffs, and pillars—tailored to your exact requirements.

Product Overview

Brass Machine Screws are threaded fasteners designed for mechanical assembly in equipment, enclosures, panels, and precision instruments. Made from high‑conductivity Brass alloys, they provide excellent corrosion resistance, electrical conductivity, and aesthetic appeal. Our screws meet international standards (DIN, ISO, BS, JIS) and can be supplied in small prototype quantities or large production runs with consistent tolerances.
