Michigan’s Premier Swiss Screw Machine Shop

In the world of precision machining, few names carry the weight and reputation of H & R Screw and Machine Company. Located in the manufacturing heartland of Michigan, H & R Screw stands at the forefront of high-precision part production, leveraging the latest in Swiss screw machine technology to serve industries where accuracy, reliability, and speed are paramount.

With decades of experience and a commitment to continuous innovation, H & R Screw has carved out a niche as a leading Swiss screw machine shop—offering unparalleled quality in the fabrication of small, intricate components for industries ranging from medical and aerospace to automotive and electronics.

What Is a Swiss Screw Machine Shop?

To appreciate the capabilities of H & R Screw, it’s important to understand the power and precision of the machines they use. A Swiss screw machine, also known as a Swiss-type lathe, is a high-precision automatic lathe designed to produce small, complex, and cylindrical parts with exceptional accuracy. These machines use a sliding headstock and guide bushing system, which allows the workpiece to move axially while remaining close to the cutting tool—minimizing deflection and enabling the machining of tight tolerances often measured in microns.

This technology is ideal for the production of long, slender parts and is widely recognized for its ability to maintain tight tolerances and excellent surface finishes, even at high production volumes.

Precision Capabilities at Scale

At H & R Screw, the company’s array of multi-axis Swiss screw machines offers unmatched production flexibility and quality control. With up to 10-axis CNC Swiss lathes, the company can perform multiple operations—such as drilling, milling, turning, threading, and knurling—in a single setup. This reduces the need for secondary machining processes, which not only speeds up production but also enhances part consistency and cost-efficiency.

Their facility is optimized for high-volume production runs, capable of producing thousands to millions of components with remarkable precision. But it’s not just about volume—their machines are equally adept at crafting prototypes or low-volume orders for clients who require early-stage product development or customized components.

Serving Critical Industries

H & R Screw’s customer base spans some of the most demanding industries in the U.S. and abroad:

• Medical: Producing micro-sized surgical screws, dental implants, and catheter components that require the utmost precision and biocompatibility.

• Aerospace: Fabricating lightweight, high-strength connectors, fasteners, and instrument components that can endure the rigors of extreme altitude and temperature fluctuations.

• Automotive: Delivering precision fuel injection components, brake system parts, and sensor housings that meet tight regulatory and performance specifications.

• Electronics: Manufacturing intricate connectors, pins, and terminals that are essential for devices where reliability and miniaturization are key.

• Industrial and Hydraulic: Supplying threaded fittings, bushings, and couplings used in fluid and power transmission systems.

By serving these diverse sectors, H & R Screw has built a resilient business model grounded in versatility and customer responsiveness.
