Introduction

Screw Machine Products are the invisible heroes of modern manufacturing. From automobiles to medical devices, these small but critical components are produced in the millions, maintaining tight tolerances and consistent quality.

At AVF Decolletage, we specialize in high-volume screw machine production, combining traditional Swiss CAM machines with advanced Swiss CNC technology. This unique hybrid approach allows us to meet the growing global demand for precision, efficiency, and affordability.

In this article, we’ll explore what screw machine products are, how they’re made, and why they remain a cornerstone of precision manufacturing in the 21st century.

What Are Screw Machine Products?

Screw machine products refer to small, turned components produced on automatic lathes — originally called “screw machines.” These parts can include:

  • Fasteners and spacers

  • Bushings and shafts

  • Connector pins and sockets

  • Standoffs, nozzles, and vent plugs

The term “screw machine” doesn’t just refer to screws — it represents any precision-machined part made by automatic turning technology.

The Evolution of Screw Machine Manufacturing

Screw machine production has evolved dramatically over the past century.

  • CAM-Driven Swiss Machines (Bechler, Tornos): Perfect for large-volume, simple geometries.

  • Swiss CNC Machines (Tsugami, Star, Citizen): Best for complex parts requiring tight tolerances and multi-operation processes.

At AVF Decolletage, we operate over 350 Swiss-type lathes — both CAM and CNC — to achieve efficiency and precision at scale.

Why Screw Machine Products Matter

Screw machine products play a vital role in nearly every industry:

  • Electronics: Connector pins, sockets, and contact terminals.

  • Automotive: Nozzles, shafts, and sensor housings.

  • Aerospace: Lightweight fasteners and specialty fittings.

  • Medical: Precision miniature components for instruments.

These parts might be small, but they’re the backbone of countless assemblies, ensuring performance, safety, and reliability.
